WARNING: The RJ-45 ports are shielded RJ-45 data sockets. You cannot
use them as standard traditional telephone sockets, or to connect the
unit to a traditional PBX or public telephone network. Only connect RJ-45
data connectors, network telephony systems, or network telephones to
these sockets. You can connect either shielded or unshielded data cables
with shielded or unshielded jacks to these data sockets.
10BASE-T/
100BASE-TX/
1000BASE-T Ports
The 10BASE-T/100BASE-TX/1000BASE-T ports have RJ-45 connectors and
are configured as Auto MDIX (cross-over).
The default state for these ports is auto-negotiation enabled, where the
link’s speed, duplex, and flow control modes are automatically detected
to provide the highest available bandwidth with the link partner.
Switch 5500 Family — Front View
17
You can disable auto-negotiation. You can manually configure these
ports to 10 Mbps half duplex, 100 Mbps half duplex,
10 Mbps full duplex, or 100 Mbps full duplex. It is not possible to
manually configure a 1000 Mbps link because auto-negotiation is
mandatory in the 1000 Mbps standard. If you disable auto-negotiation,
Auto MDIX cannot function and the ports become fixed in MDIX
(cross-over) mode.
If you disable auto-negotiation on a 1000 Mbps port, the speed drops to
the highest available speed, which is 100 Mbps by default.
1000BASE-X SFP Ports
The 1000BASE-X SFP (Small Form Factor Pluggable) ports support fiber
Gigabit Ethernet short-wave (SX), long-wave (LX), long-haul (LH70), and
copper (T) SFP Transceivers in any combination. This offers you the
flexibility of using SFP transceivers to provide connectivity between the
Switch and remote 1000 Mbps workgroups, or to create a high capacity
aggregated link backbone connection.
The default state for these ports is auto-negotiation enabled, where the
speed, duplex and flow control modes are negotiated. As the speed and
duplex modes are fixed by the media type, only the flow control is
negotiated with the link partner. Alternatively, auto-negotiation can be
disabled (except 1000BASE-T where auto-negotiation is mandatory) and
the flow control setting can be manually configured.
You can also use these ports for stacking the 5500 SI and EI. For
information about stacking these switches, see the section entitled
“Guidelines For Interconnecting Units” on page 78.
100BASE-X SFP Ports
(Switch 5500-EI FX
only)
The Switch 5500-EI FX has 24 100BASE-X SFP ports. These are 100Mbps
ports that can use multi-mode fiber optic cables of up to 2km and
single-mode fiber optic cables of up to 10km.
You must manually configure duplex and flow control.
The Switch 5500-EI FX supports copper transceivers on the Gigabit SFP
ports only.
Console Port
The console port allows you to connect a terminal and perform remote or
local out-of-band management. As the console port on the Switch is an
RJ-45 port, you must connect an RJ-450 to DB9 converter cable to a
standard null modem cable in order to connect a terminal.

CHAPTER 1: INTRODUCING THE SWITCH 5500 FAMILY
Unit LED
LEDs
The Unit LED is a seven segment display visible on the front of the Switch.
The Unit LED indicates the unit number in a fabric, POST test ID, and
software upgrade information. In the unlikely event of a hardware fault
occurring, you can use the Unit LED to help diagnose the problem. For
information on using the Unit LED for problem solving, see “Solving
Problems Indicated by LEDs” on page 82.
Table 5 lists the LEDs visible on the front of the Switch, and how to read
their status according to color. For information on using the LEDs for
problem solving, see “Checking for Correct Operation of LEDs” on
page 43.

Connecting a
Redundant Power
Supply
The Switch 5500 Family has a -48V DC Redundant Power Supply socket.
WARNING: Only properly trained and qualified personnel should install
the Redundant Power Supply (RPS).
WARNING: Make sure to read these instructions in conjunction with the
RPS flyer and the safety and installation instructions supplied with your
RPS.
36
CHAPTER 2: INSTALLING THE SWITCH
WARNING: When powering any Switch 5500 from an RPS, make sure
that the unit is earthed (grounded) by either connecting the power cord
to the unit or by connecting the earth terminal on the rear of the unit to
a reliable electrical earth (or by connecting both). Ensure that the earth
connection is made before connecting the DC supply from the RPS.
3Com switches that support -48V DC RPS inputs, and are PoE enabled,
can only be powered by an RPS that complies with the isolation
requirements of IEEE-Std 802.3af. Non PoE enabled switches do not have
this restriction.
WARNING: Do not use a standard 'positive-earthed' -48V redundant
power system suitable for use with telecommunications equipment with
the 3Com Power-over-Ethernet (PoE) network switches. In order to meet
the IEEE 802.3af (PoE) specification, the -48V output must be isolated
from earth (ground) and meet the isolation requirements in that
specification.
WARNING: Any RPS must be approved as a SELV output in accordance
with IEC 60950-1/UL 60950-1/EN 60950-1.
WARNING: The characteristics of the Switch 5500 DC supply input are
provided in Appendix C on page 127.
You can power the Switch 5500 using three methods:
■
AC Mains only — this does not offer any power redundancy. If the
AC mains supply or the AC power supply fails, the switch powers off.
■
AC Mains and -48V DC (primary supply) — the internal AC supply
acts as the backup in the event of a DC power failure.
■
DC only — the switch does not need an AC supply and the resiliency
is provided by the DC supply. This is useful in environments where only
DC power is available.
The RPS provides three main benefits:
■
Power Redundancy — if a switch is powered from the mains supply
unit, a failure of the internal power supply causes the switch to fail.
You can avoid this by connecting both the AC and DC RPS supplies to
the switch. You can also add redundancy to the DC power by using
(N+1) DC power supplies to further increase the availability of the
system.
Connecting a Redundant Power Supply
37
■
Uninterruptable Power — the system allows easy connection and
maintenance of batteries to the RPS shelf to further increase the
availability of the system.
■
Additional Power to PoE Ports — the PoE switch’s internal AC
Power Supply provides enough power for most network applications.
You can use the RPS to supplement power (up to a maximum of
15.4W), including full backups of all PoE devices on the network.
Table 13 outlines the behavior of the switch when changes occur to the
power system, such as removing the AC mains cable when the RPS is
attached. The responses to the different power inputs are controlled by
the switch’s internal power supply and not by the RPS.

CHAPTER 2: INSTALLING THE SWITCH
Specifying the
Redundant Power
System
3Com’s redundant power solution allows you to use any off-the-shelf
-48V DC RPS that meets the requirements defined in Appendix C on
page 127.
For an approved vendor list, more details about purchasing the 3Com
recommended RPS, and a full set of requirements go to:
http://www.3Com.com/RPS
The 3Com recommended RPS generates -48V DC power using power
supply units (or rectifiers). The outputs of the rectifier(s) are connected
together so that you can increase the total -48V power available by
adding rectifiers. For example, three 1500W rectifiers can provide up to
4500W. Hot removal or insertion of a rectifier does not affect the -48V
DC output voltage.
Table 14 shows an example of the total power available from several
1500W rectifiers.
A minimum of two rectifiers are required for each shelf to provide N+1
rectifier redundancy.

The unearthed -48V DC power distribution provides the mechanism to
connect to the Switch 5500. The distribution consists of several circuit
breakers and connection terminals for the positive (common) and
negative -48V outputs. Individually connect each Switch 5500 to a circuit
breaker terminal.
You can also connect a battery to battery terminals prior to the DC power
distribution to provide uninterrupted power and to be protected against
the loss of AC mains power.
Connecting a Redundant Power Supply
39
3Com’s RPS solution uses -48V DC power distribution. The RPS system
provides bulk -48V DC power that is separately distributed to a number
of network switches.
Each RPS consists of a shelf that can house from one to six rectifiers, a
Distribution Module, and a Management Module.
Connecting the
Switch to the
Redundant Power
System
When connecting the RPS to the switch, the circuit breaker and 2-core
cables need to be matched to the switch’s power rating. Table 15 shows
the recommended circuit breaker and cable rating for the Switch 5500.
The recommended cable length should not exceed three metres (9.84
feet).

Non PoE
6A C type
18 AWG (solid or stranded cable)

WARNING: Make sure to follow the RPS Manufacturers
recommendations when connecting the cable to the RPS.
WARNING: Ensure that the circuit breaker in the RPS is in the open (off)
position when connecting the cable to the RPS and the cable and
connector to the switch.
WARNING: You must ensure that the positive terminal on the switch is
connected to the positive (common) terminal of the RPS and that the
negative terminal on the switch is connected to the negative (circuit
breaker) terminal of the RPS.
Figure 17 shows how to connect the power supply to the RPS socket in
the back of the switch. Use the cable tie supplied with your switch to
support the cable in the back of the RPS connector as shown in Figure 17.

When the RPS is connected to the switch, you can move the circuit
breaker in the RPS to the closed (on) position and the switch will be
powered by the -48V DC power.
The -48V DC power takes priority over the AC mains and powers the
switch if it is connected.
Connecting the
Earthing Cable
Use the earthing cable that accompanies your switch if the length is
suitable. Alternatively use the earthing cable specification as defined in
Appendix C on page 127.
The earthing cable is only required if the switch is powered by the RPS
only.
The recommended cable length should not exceed three metres (9.84
feet).

The Switch 5500G-EI Power over Ethernet (PoE) units can supply power
to any IEEE 802.3af compliant device through any of its front panel ports
over a Category 5 or Category 5e Ethernet cable. The same cable
connects the device to the network.
The Switch 5500 units can supply power through the 10/100 ports only.
Power over Ethernet is a self-configuring protocol. When you plug a PoE
compliant device into one of the ports on the switch, the switch supplies
the power required to the device, providing that the total power budget
for the switch is not exceeded.
A PoE switch combines the functionality of a standard Ethernet switch
with a single power supply that can power multiple devices. Using a PoE
switch has the following advantages over an non-powered network.
■
Reduced Cabling — a PoE (802.3af) compliant device that has its
power supplied over its Ethernet cable does not require a separate
power supply. If, for example, you use the switch to connect a 3Com
11 Mbps Wireless LAN Access Point 8500 to the network, then only a
network cable is required to provide both power and network
connectivity.
■
Increased Reliability — a device powered by a PoE switch can take
advantage of the facilities available to the switch. You can fit the
switch with a redundant power supply or uninterruptible power
supply to increase its uptime.
The switch supports resistor detection according to IEEE 802.3af and
pre-standard detection methods.

using the web interface or the command line interface (CLI).
Installing and
Removing the
Power Module
Installing the Power
Module
The Switch 5500G Family Power Module is swappable. To install the
power module:
1 Wear an ESD wrist strip, and make that sure it is well grounded.
2 Verify that the Power Module is not installed upside-down (the module
should be installed according to the letters. If the module is installed
upside down, it will not be fully seated due the design of the chassis’
internal structure).
3 Use one hand to hold the handle on the front, and another to hold the
bottom. Slide it gently along the power slot. Push the module until it is
fully seated.
4 Use a Phillips screwdriver to fasten the screws at both sides of the
module.
Removing the Power
Module
To remove the Power Module:
1 Wear an ESD wrist strip, and make sure it is well grounded.
2 Disconnect all power to the switch.
3 Use a Phillips screwdriver to unscrew the screws on both sides of the
module.
4 Use one hand to hold the handle on the front, and another to hold the
top. Pull out the module stably towards you along the power slot until it
is completely apart from the chassis bottom.
Placing Units On Top of Each Other
43
CAUTION: When you use the Phillips screwdriver or power screwdriver to
fasten captive screws on both sides of the module, make sure the captive
force moment is not larger than 0.4 Nom.
Placing Units On
Top of Each Other
If the switch units are free-standing, you can stack up to eight units. If
you are mixing a variety of switches, make sure to place the smaller units
at the top.
If you are stacking switch units, apply the supplied self-adhesive rubber
feet to the underside of each switch. Stick one in the marked area at each
corner. Place the switch units on top of each other, ensuring that the feet
of the upper unit sit fully on the lower unit.
The Power-up
Sequence
Powering-up the
Switch 5500
The following sections describe how to prepare your Switch 5500 for
operation.
To power-up the switch:
1 Plug the power cord into the power socket at the back of the switch.
2 Plug the other end of the power cord into your power outlet.
The switch powers-up and runs through its Power On Self Test (POST),
which takes approximately one minute.
Checking for Correct
Operation of LEDs
During the POST, all ports on the switch are disabled and the LEDs blink in
a rapid sequence.
When the POST has completed, check the Unit Status to make sure that
your switch is operating correctly. Table 17 describes the possible LED
colors.
44
CHAPTER 2: INSTALLING THE SWITCH

The switch is not receiving power.
If you encounter a problem, see the section entitled “Solving Problems
Indicated by LEDs” on page 82 for a list of suggested solutions.
CAUTION: The switch has no ON/OFF switch; the only method of
connecting or disconnecting mains power is by connecting or
disconnecting the power cord.
Choosing the Correct
Cables
All of the ports on the switch are Auto-MDIX, that is, they have a
cross-over capability. These ports can automatically detect whether to
operate in MDI or MDIX mode. Therefore, you can make a connection to
one of the ports with a straight-through (MDI) or a cross-over (MDIX)
cable.
The Auto-MDIX feature only operates with auto-negotiation enabled.
If auto-negotiation is disabled, all the switch ports are configured as
MDIX (cross-over). If you want to make a connection to another MDIX
port, you need a cross-over cable. Many ports on workstations and
servers are configured as MDI (straight-through). If you want to make a
connection to an MDI port, you need to use a standard straight-through
cable. See Table 18.
3Com recommends that you use at least Category 5 twisted pair cable.
The maximum segment length for this type of cable is 100 m (328 ft.).

CAUTION: If you want to install the switch using a Category 5E or
Category 6 cable, 3Com recommends that you briefly connect the cable
to a grounded port before connecting network equipment, otherwise the
cable’s Electrostatic Discharge (ESD) may damage the switch's port.
You can create a grounded port by connecting all wires at one end of a
UTP cable to an earth ground point, and the other end to a female RJ-45
connector located, for example, on a switch rack or patch panel. The
RJ-45 connector is now a grounded port.
WARNING: The Switch 5500G-EI supports Power over Ethernet on all
front ports. The Switch 5500 PWR supports Power over Ethernet on the
10/100 ports only. Use these ports for Ethernet wiring within the same
building only.
Choosing the Correct
Cables for the
1000BASE-X SFP Ports
The 1000BASE-SX SFP transceiver supports a direct connection to a
multi-mode fiber-optic cable. The 1000BASE-LX SFP transceiver supports
a direct connection to single-mode and multi-mode fiber-optic cables.
The 1000BASE-LH70 SFP transceiver supports a direct connection to a
single-mode fiber-optic cable. The 1000BASE-T SFP transceiver uses
Category 5 copper cabling with RJ-45 connectors and supports segment

SFP Operation
Inserting an SFP
Transceiver
49
To activate the SFP ports:
SFP transceivers are hot-insertable and hot-swappable. You can remove
them from and insert them into an appropriate SFP port without having
to power down the switch.
1 The SFP transceiver (shown in Figure 18) is keyed so that there is only one
way that you can install it correctly. Hold the transceiver so that the
connector is toward you and the product label is visible. Ensure that the
wire release lever is closed (in the upright position).
2 Gently slide the transceiver into the SFP port until it clicks. If the
transceiver does not click into place, remove it, turn it over and re-insert
it.
3 Remove the plastic protective cover, if fitted.
CAUTION: The dual personality ports on the Switch 5500G-EI enable you
to activate an RJ-45 port, an SFP port, or a mixture of both (for example,
on the 24 Port switch, you can activate the RJ-45 ports 23 and 24 and the
SFP ports 21 and 22 at the same time). If you try to activate the same dual
personality RJ-45 port and SFP port (for example, RJ-45 port 23 and SFP
port 23 at the same time), the SFP port takes priority.

SETTING UP FOR MANAGEMENT
To make full use of the features offered by your switch, and to change
and monitor the way it works, you use management software that
resides on the switch. Managing the switch can help you to improve its
efficiency and, therefore, the overall performance of your network.
This chapter explains the initial setup and the methods by which you can
access the management software to manage the switch. It includes the
following topics:

There are two main views in the CLI:
■
User View — this view displays when you first connect to the switch
and provides basic information about its operation and statistics. The
prompt for user view is <SW5500-XX> (where xx is either SI or EI).
■
System View — this view enables you to configure the system
parameters. To display this view, from user view enter system-view.
The prompt for system view is [SW5500-XX].

If you use SSH to administer your switch, and the network traffic is
intercepted, no passwords or configuration information are visible in the
data. To securely administer the switch using the Command Line Interface
you need a third party SSH client.
Each switch has an internal set of Web pages that allow you to manage
the switch using a Web browser remotely, over an IP network (see
Figure 23).

CAUTION: To protect your switch from unauthorized access, you must
change all three default passwords as soon as possible, even if you do not
intend to actively manage your switch. For more information on the
default user names and changing the default passwords, see “Changing
the Default Passwords” on page 73.
IP Configuration
You can use one of the following methods to provide IP information to
your switch. This step is essential if you wish to manage your switch over
the network.
Manual IP Configuration
When you configure the IP information, the switch retains that
information that you enter until you change it again.
You should use the Manual IP configuration method if:
■
you do not have a DHCP or BootP server on your network
■
you want to remove the risk of the IP address ever changing
■
your DHCP or BootP server does not allow you to allocate static IP
addresses. Static IP addresses are necessary to ensure that the switch is
always allocated the same IP information.
For most installations, 3Com recommends that you manually configure
the switch’s IP information. This makes management simpler and more
reliable since it does not depend on a DHCP or BootP server. It also
eliminates the risk of the IP address changing.
To manually enter the switch’s IP information, refer to the section entitled
“Manually Configuring the IP Information” section on page 61.
Automatic IP Configuration using DHCP
By default, the switch automatically attempts to acquire its IP address
from a DHCP server on the network. If you are using this method, make
sure your DHCP server assigns the switch a static IP address so that you
know what that IP address will be at all times.
If you do not know what the IP address is and it will be difficult to
manage your switch. Most DHCP servers allow static IP address
configurations. Refer to your DHCP server documentation for
instructions.
60
CHAPTER 3: SETTING UP FOR MANAGEMENT
For a detailed description of how automatic IP configuration operates,
refer to the “Switch 5500 Family Configuration Guide” available on
3Com’s Web Site at www.3com.com.
You should use the automatic IP configuration method if:
■
your network uses DHCP to allocate IP information
■
the switch is deployed on a different subnet. In this case, the switch
will automatically reconfigure itself with an appropriate IP address,
rather than you having to manually reconfigure the switch.
If the switch is not allocated with an automatic IP address, the IP
configuration will be blank or shown as ‘’’’.
If you use the automatic IP configuration method, you need to discover
the automatically allocated IP information before you can begin
management. Refer to the section entitled “Viewing Automatically
Configured IP Information” section on page 67.
Preparing for
Management
Once your switch’s initial set up is complete you can set up your chosen
management method as described in “Methods of Managing a Switch”
on page 56.
For detailed information about the specific Web interface operations,
command line interface commands, and problem solving, refer to the
“Switch 5500 Family Command Reference Guide” available on 3Com
Web Site at www.3com.com.
Manually Configuring the IP Information
Manually
Configuring the IP
Information
Connecting to the
Console Port
61
You can manually configure the switch’s IP information by:
■
Connecting a workstation using a console cable to the switch’s
console port. You can then manually enter IP information using the
command line interface (CLI).
■
Connecting a workstation using an Ethernet cable to a front panel
port of the switch. You can then manually enter IP information using
the web interface or the command line interface (CLI).
To set up your switch manually, you can connect to the console port, (this
example describes a local connection to the console port, rather than one
using a modem). You can do this while the switch is offline (before you
connect the switch to a network) or while the switch is online (connected
to a network).
Prerequisites
Before configuring your switch, make sure that you have:
■
A workstation with terminal emulation software installed, such as
Microsoft Hyperterminal. This software allows you to communicate
with the switch using the console port directly.
■
Documentation supplied with the terminal emulation software.
■
The console cable (RJ-45) supplied with your switch.
The cable’s pin-out diagrams are provided in “Pin-outs” on page 123.
■
An IP address
■
A subnet mask
■
A default gateway
■
A management VLAN ID, normally set to the default value (1)

To set up your switch manually you can, alternatively, make a connection
to a front panel port. To do this you need an IP address. Refer to
“Viewing Automatically Configured IP Information” on page 67 for more
information.
The procedure described in this section assumes the unit is powered up in
standalone mode.
Prerequisites
Before configuring your switch, make sure that you have:
■
A workstation running a suitable operating system. Refer to
“Choosing a Browser” on page 71.
■
A Network Interface Card (NIC).
■
A Category 5 twisted pair Ethernet cable with RJ-45 connectors at
both ends.
■
A suitable Web browser. Refer to “Choosing a Browser”on page 71.
■
The switch’s IP address.
■
An IP address
■
A subnet mask
■
A default gateway
■
A management VLAN ID, normally set to the default value (1)
Connecting the Workstation to the Switch

a Attach an RJ-45 connector at one end of the Ethernet cable to the
Network Interface Card (NIC) in the workstation.
b Connect the RJ-45 connector at the other end of the cable to one of
the front panel ports on the switch.
Do not interconnect the switch to any other unconfigured switch.
Setting Up the Switch with IP Information
You can set up the switch with IP information using the Web interface or
the command line interface (CLI) using telnet.
Using the Web Interface
1 Power-up the switch. This takes approximately one minute.
2 Open a suitable Web browser and enter your switch’s IP address in the
Address field.
If there is no response, wait for one minute then re-enter the IP address.
If your browser displays an option to install simplified Chinese characters,
click Cancel to continue (do not install these characters).
3 At the Username prompt, enter admin as your user name and press
Return. At the password prompt press Return again. The switch’s Device
View displays.
4 To enter basic setup information for the switch, select Administration > IP
Setup and follow the wizard screens to enter the IP address and subnet
mask that you want the switch to use when it is connected to the
network. The final page displays a summary of the information entered.
5 Select Save Configuration to save the configuration to your switch.
You can now set up your switch management method. See “Methods of
Managing a Switch” on page 56 to determine which method is best for
you.

CHAPTER 3: SETTING UP FOR MANAGEMENT
Using the Command Line Interface through Telnet
1 To start a Telnet session to the unit, from Microsoft Windows, click Start >
Run. In the Open field type Telnet xxx.xxx.xxx.xxx (where
xxx.xxx.xxx.xxx is the switch’s IP address) and click OK.
2 Press Enter to open a login prompt.
If the login prompt does not begin immediately, press Return a few times
until it starts.
3 At the Username prompt, enter admin as your user name and press
Return. At the password prompt press Return again. If you have logged
on correctly, <5500G-EI> or <5500-xx> is displayed (where xx is either
SI or EI) as shown in the example in Figure 29.
Figure 29 User View Login using Telnet
4 Enter the system-view command and press Enter.
5 Enter interface vlan 1 and press Enter.
6 Enter the IP address and subnet mask for the switch as follows:
ip address xxx.xxx.xxx.xxx mmm.mmm.mmm.mmm
(where xxx.xxx.xxx.xxx is the IP address and mmm.mmm.mmm.mmm is
the subnet mask of the switch)
7 Enter the default gateway for the switch:
ip route-static 0.0.0.0 0.0.0.0 xxx.xxx.xxx.xxx
(where xxx.xxx.xxx.xxx is the IP address of the default gateway)
8 From the User View, enter the save command to save the configuration
to your switch because the configuration is not saved automatically when
you power down the switch.
Viewing Automatically Configured IP Information
67
You can now set up your switch management method. See “Methods of
Managing a Switch” on page 56 to determine which method is best for
you.
Viewing
Automatically
Configured IP
Information
Using 3Com Network
Director
If you allow the switch to automatically configure its own IP information,
you need to discover and view the IP information before you can begin to
manage the switch. You can discover the IP information in two ways:
■
Using 3Com Network Director to auto-discover the switch and display
the automatically allocated IP information assigned to the switch.
■
Connect a workstation using a console cable to the switch’s console
port. You can then view the IP information automatically assigned to
the switch using the command line interface (CLI).
To use the 3Com Network Director application (available from the 3Com
Web site) to discover the automatically allocated IP information:
1 Connect your switch to the network.
2 Power-up the switch and wait for two minutes.
3 Launch 3Com Network Director and run the Auto-discovery wizard.
3Com Network Director automatically discovers the new switch and
displays the IP information allocated to the switch.
Most DHCP and BootP servers allow you to configure static IP addresses
so that you know what IP address is given to the switch. Refer to the
documentation that accompanies your DHCP or BootP server for
instructions.
If your network does not have a DHCP or BootP server, the workstation
running 3Com Network Director must be on the same subnet as the
switch because Auto-IP addresses are non-routable.
Connecting to the
Console Port
You can view the automatically configured IP information using the
command line interface (CLI) through a connection to the console port.
This example describes a local connection to the console port rather than
a remote connection using a modem. For further information on
connecting to the console port see “Connecting the Workstation to the
Switch”on page 62.
68
CHAPTER 3: SETTING UP FOR MANAGEMENT
Viewing IP Information via the Console Port
To view the automatically-allocated IP information using the command
line interface:
1 Connect your switch to the network using the Ethernet cable. As soon as
a network connection is made the switch begins the automatic IP
configuration process.
The automatic IP configuration process usually completes within one
minute.
2 The command line interface login sequence begins as soon as the switch
detects a connection to its console port.
If the login prompt does not begin immediately, press Return a few times
until it starts.
3 At the username prompt, type admin and press Return. Press Return
again at the password prompt. If you have logged on correctly,
<500G-EI> or <5500-xx> is displayed (where xx is either SI or EI) as
shown in the example in Figure 30.
Figure 30 User View Login
4 Enter display ip interface br to view a summary of allocated IP
addresses.
You can now set up your switch management method. See “Methods of
Managing a Switch” on page 56 to determine which method is best for
you.
If you do not intend to use the command line interface through the
console port to manage the switch, you can logout, disconnect the serial
cable, and close the terminal emulator software.

Overview
CLI Management
through the Console
Port
69
This section describes how to set up command line interface
management using a local console port connection or over the network.
The switch provides a user interface so that you can configure and
manage the port data. There are two types of user interfaces, AUX and
VTY:
■
Use the AUX user interface to log into your switch through the
console port. A fabric can have up to eight AUX user interfaces.
■
Use the VTY user interface to Telnet to the switch. The switch can
have up to five VTY user interfaces.
To manage a switch using the command line interface through the local
console port connection, ensure that you have connected your
workstation to the console port as described in “Connecting to the
Console Port” on page 61.
You can now continue to manage and configure your switch using the
CLI through its console port.
CLI Management over
the Network
To manage a switch using the command line interface over a network
using Telnet:
1 Ensure that you have already set up the switch with IP information as
described in “Methods of Managing a Switch” on page 56.
2 Check that the IP protocol is correctly installed on your management
workstation. You can check this by trying to browse the World Wide
Web. If you can browse, the IP is installed correctly.
3 Check that you can communicate with the switch by entering a ping
command at the DOS prompt in the following format:
c:\ ping xxx.xxx.xxx.xxx
(where xxx.xxx.xxx.xxx is the switch’s IP address)
If you get an error message, check that your IP information has been
entered correctly and that the switch is powered up.
4 To open a Telnet session, from the DOS prompt, enter the IP address of
the switch that you wish to manage in the following format:
>telnet xxx.xxx.xxx.xxx
70
CHAPTER 3: SETTING UP FOR MANAGEMENT
(where xxx.xxx.xxx.xxx is the IP address of the switch)
If you are opening a Telnet session using third party software, you must
enter the IP address in the format suitable for that software.
5 At the Username prompt, enter admin as your user name and press
Return. At the password prompt press Return again. (or enter the
password if you have modified the default passwords).
If the login prompt does not display immediately, press Return a few
times until it starts.
6 If you have logged on correctly, the switch prompt display as
<5500G-EI> or <5500-xx> (where xx is either SI or EI, as shown in
Figure 27 on page 63).
Setting Up
Command Line
Interface
Management using
SSH
This section describes to can set up command line Interface management
using SSH over a network.
To manage a switch through the command line interface over a network
using SSH:
1 Ensure that you have set up the switch with IP information as described in
“Methods of Managing a Switch” on page 56.
2 Check that you have the IP protocol correctly installed on your
management workstation. You can check this by trying to browse the
World Wide Web. If you can browse, the IP is installed correctly.
3 Check that you can communicate with the switch by entering a ping
command at the DOS prompt in the following format:
c:\ ping xxx.xxx.xxx.xxx
(where xxx.xxx.xxx.xxx is the IP address of the switch)
If you get an error message, check that your IP information has been
entered correctly and that the switch is powered up.
The switch automatically generates a host key pair when it is powered up
for the first time, or after any reset to factory defaults. Host key
generation may take a while, during which time SSH connections to the
switch will be refused.
4 Install an SSH client application on the workstation from which you want
to use to access the switch.
3Com recommends the PuTTY, OpenSSH, and SSH Communications
Security Corp Secure Shell SSH clients.
Setting Up Web Interface Management
71
5 Open an SSH session and access the switch using the switch’s IP address
and port number.
The first time you connect to the switch, the client asks you to confirm
that the host key is correct for the device.
6 The switch and the SSH client authenticate each other and a secure
connection is established. Enter your username and password to access
the CLI commands.
For increased security, you should change the default password when
using SSH for the first time.
For further information on generating a host key on your switch and
transferring keys to the switch using TFTP server, refer to the
Configuration Guide.
Setting Up Web

For the browser to operate the Web interface correctly, make sure that
JavaScript™ and Cascading Style Sheets are enabled on your browser.
These features are enabled on a browser by default. You will only need to
enable them if you have changed your browser settings.
Web Management
Over the Network
To manage a switch using the Web interface over an IP network:
1 Check that you have the correct IP information configured on your
management workstation. You can check this by trying to browse the
World Wide Web. If you can browse, the IP is installed.
2 Check that you can communicate with the switch by entering a ping
command at the DOS prompt in the following format:
c:\ ping xxx.xxx.xxx.xxx
(where xxx.xxx.xxx.xxx is the IP address of the switch)
If you get an error message, check that your IP information has been
entered correctly and that the switch is powered up.
3 Open your Web browser and enter the switch’s IP address in the URL
locator, for example, in the following format:
http://xxx.xxx.xxx.xxx

Return. At the password prompt press Return again. (or enter the
password if you have modified the default passwords).
5 Click on the Device View button to display the web management options.
Setting Up SNMP
Management
Any network management application running the Simple Network
Management Protocol (SNMP) can manage a switch if the management
workstation is connected to the switch using a port on the management
VLAN. By default, the management VLAN is 1, and all ports on the
switch are in VLAN 1
You can use the 3Com Network Director, Device manager, EMC and the
OV integration kit (available from 3Com’s Web site) to provide SNMP
management for your switch. 3Com Network Director, Device manager,
EMS, and OV integration kit automatically loads the correct MIBs and
necessary files onto your workstation.
Prerequisites
The default read community string is public. To change this setting, in
System View, enter display snmp community.
Changing the Default Passwords
73
The default write community string is private. To change this setting,
in System View, enter display snmp community.
To manage your switch using an SNMP network management
application, you need to specify the same SNMP community strings for
the users defined on the switch and the management application.
You can do this using the command line interface system
management snmp community command. Refer to the command
line interface section of the “Switch 5500 Family Command Reference
Guide” for more information.
SNMP V3 is on as default. All commands are in the SNMP menu in System
View.
Changing the
Default Passwords
If you intend to manage the switch using the Web interface or the
command line interface, or to change the default passwords, you need to
log in with a valid user name and password. The switch has three default
user names, and each user name has a different password and access
level. These default users are listed in Table 22.
CAUTION: To protect your switch from unauthorized access, you should
change all three default passwords as soon as possible, even if you do not
intend to actively manage your switch.

CREATING AN XRN STACKING
FABRIC
This chapter contains the information you need to create an XRN
Stacking Fabric. It covers the following topics:
How To
Interconnect Units
■
How To Interconnect Units
■
Guidelines For Interconnecting Units
■
Unit Numbering within the Fabric
Up to eight 3Com Switch 5500 units can be interconnected to create an
XRN Stacking Fabric and then treated as a single manageable unit with
one IP address.
You can interconnect your switches to create an XRN Fabric using a
standard 1000 Mbps Ethernet connection. Table 23 lists the different
variants of the Switch 5500 family, how they physically interconnect and
the level of XRN support offered by the Fabric.
It is not possible to create a Fabric by interconnecting a 3Com Switch
5500 with any other 3Com device (such as a 5500G-EI) or mix Enhanced
Image (EI) Switch 5500 units with Standard Image (SI) units.
This section assumes you have either set up your units for management
as detailed in Chapter 3 “Setting Up SNMP Management”or that you are
using a console cable connected to the console port to set up and
allocate IP addresses and so on.
For more information on creating an XRN Fabric, refer to the Installation
Guides that accompany the stacking cable (3C17262) and the resilient
stacking cable (3C17263).

Stacking Switch 5500 Units
1 Ensure that the switch units that you wish to interconnect have the latest
software agent installed. You can use the display version
command to check this.
2 Enable the ‘up port’ and the ‘down port’ on each switch (see Table 23) to
operate in Fabric mode using the following CLI command. From the
System View enter fabric-port gigabitethernet 1/0/51
enable, for example.
How To Interconnect Units
77
As with all Switch 5500 CLI commands, the format for entering a
command that is port specific is x/y/z, where x = unit number, y = module
number (in the case of the Switch 5500 this will always be 0), z = port
number.
3 Connect the Fabric-enabled ‘up’ port on one Switch 5500 unit to the
Fabric-enabled ‘down’ port on another Switch 5500 unit using the
appropriate connection method for your switch as detailed in Table 23.
4 To create a fully resilient Fabric: enable the spare Fabric ports on the
top-most and bottom-most units in the Fabric as described in the
previous steps. Then insert a cable into these two Fabric ports to create a
link between the top-most and bottom-most units in the Fabric, as shown
in Figure 31 on page 79.
This ensures that in the event of a unit failure within the Fabric, the Fabric
will continue working and no “Fabric split” will occur.
Save all configuration settings. From the User View, enter the save
command to save the configuration to your switch.
Stacking Switch 5500G-EI Units
1 Ensure that the switch units that you wish to interconnect have the latest
software agent installed. You can use the display version
command to check this.
2 Connect the stacking cable ‘up’ port on one Switch 5500G-EI unit to the
stacking cable ‘down’ port on another Switch 5500G-EI unit using a
stacking cable (3C17262) or a resilient stacking cable (3C17263).
Note the color code on the stacking cable connectors should match the
color code on the stacking ports, that is, blue for the ‘up’ port that is
connecting to the physically higher unit, and yellow for the ‘down’ port
that is connecting to the physically lower unit.
3 To create a fully resilient Fabric: using the ‘up’ stacking cable port on the
top-most and the ‘down’ stacking cable port on the bottom-most units
insert a stacking cable to create a link between the top-most and
bottom-most units in the Fabric, as shown in Figure 31 on page 79.
This ensures that in the event of a unit failure within the Fabric, the Fabric
will continue working and no “Fabric split” will occur.
4 Save all configuration settings. From the User View, enter the save
command to save the configuration to your switch.
78
CHAPTER 4: CREATING AN XRN STACKING FABRIC
Guidelines For
Interconnecting
Units
This section offers some guidelines for creating a Fabric. Using these
guidelines will help prevent problems arising when setting up your Fabric.
■
The maximum number of switch units that can be interconnected is
eight.
■
It is not possible to create a Fabric by interconnecting a 3Com Switch
5500 with any other 3Com device (such as a 5500G-EI) or mix
Enhanced Image (EI) Switch 5500 units with Standard Image (SI) units.
■
3Com strongly recommends that you upgrade all switches to be
interconnected to the latest software agent.
■
3Com recommends that you remove the configuration file from a
switch unit that has previously been used elsewhere in your network
before you interconnect to an existing unit. If you do not do this,
problems may be caused by conflicting switch configurations. Use the
dir command from the User View to display the configuration files
stored on the switch and locate the [filename].cfg file. Do NOT
under any circumstances remove the 3comoscfg.def file (this is the
default configuration file).
For a detailed description of how XRN Technology operates and
implementation guidelines, refer to the “Switch 5500 Family
Configuration Guide” available on the 3Com Web Site at
www.3com.com.
Unit Numbering
within the Fabric
When a Fabric is created using the Switch 5500 the unit numbering can
be determined in two ways.
■
You can manually assign unit IDs 1 to 8 to specific units using the
change[self-unit, unit-id] to [1-8,
auto-numbering] command from the System View. If you
manually assign unit IDs to a switch via the change command the IDs
will be retained after a power cycle.
If you add a unit to a Fabric that has previously been manually
configured with a unit ID and this conflicts with an ID already within
the Fabric, then the switch with the lowest MAC address assumes the
ID in question and the other unit will automatically renumber.
3Com recommends that you manually assign the unit IDs within the
Fabric if you wish to have predictability of knowing which units have
which IDs at all times.
Unit Numbering within the Fabric
■
79
Fabric topology is ‘discovered’ and the units auto-number their IDs.
Adding and removing units from the Fabric does not cause any
renumbering to occur and the Fabric will continue to work normally.
Renumbering only occurs when the Fabric is next power cycled if the
units are configured to auto-number.
The unit LEDs will display the unit number in the Fabric, from 1 to 8.

Guide on the CD-ROM that accompanies your switch.
For Technical Support information, see Appendix D.
82
CHAPTER 5: PROBLEM SOLVING
Solving Problems
Indicated by LEDs
If the LEDs on the switch indicate a problem, refer to the list of suggested
solutions below.
The PWR LED does not light
Check that the power cable is firmly connected to the switch and to the
supply outlet. If the connection is secure and there is still no power, you
may have a faulty power cord or an internal fault. Firstly, check the power
cord by:
■
testing it in another device.
■
connecting a working power cord to the ‘problem’ device then
contact your supplier for advice.
On powering-up, the PWR LED lights Red
The switch unit has failed its Power On Self Test (POST) because of an
internal problem. The fault type will be indicated on the unit LEDs.
Contact your supplier for advice.
On powering-up, the PWR LED is flashing yellow
A port has failed and has been automatically disabled. You can verify this
by checking that the Port LED is quickly flashing Yellow. If a port fails, the
switch passes its Power On Self Test and continues to operate normally.
A Port LED is flashing yellow
The port has failed and has been automatically disabled. The switch
passes its Power On Self Test and continues to operate normally, even if
one or more ports are disabled.
A link is connected and yet the Port LED does not light
Check that:
■
The switch and the device at the other end of the link (or cable) are
connected securely.
■
The devices at both ends of the link are powered-up
■
The quality of cable is satisfactory
■
Auto-negotiation settings are the same at both ends.

end and not at the auto-negotiation end)
In the rare event of your switch unit experiencing a hardware failure, refer
to the list of suggested solutions below.
A fan failure warning message is received
Your switch has a fan monitoring system that will generate fan failure
warning messages. Fan failure could potentially reduce the lifetime of the
switch. The monitoring system polls the fan status at periodic intervals
while the unit is powered up.
If one fan has failed in the switch, a warning message will be generated
in the following ways:
■
Unit LED — the seven segment display will show a green flashing ‘f’.
■
RMON Trap — if configured, an RMON trap is generated and sent to
the management workstation.
■
Command Line Interface — an indication of a general hardware
failure is provided through the Top level menu displayed when logging
on to the CLI. For more detailed information about the failure select
the display logbuffer command.
■
Web interface — an indication of fan failure is provided through the
Device Summary table for the specific unit. In addition all Summary
tables turn red to indicate the fan failure.
If a fan failure warning message is generated:
1 Power off the unit.
2 Check that the air vents are not obstructed.
84
CHAPTER 5: PROBLEM SOLVING
3 Power cycle the unit. To do this, remove and reconnect the AC mains
supply. If the unit has no AC main supply, remove and reconnect the DC
RPS supply.
4 If another fan failure warning message is generated via the Command
Line Interface or the Web interface, return the unit to 3Com.
Unit fails, no SNMP fan failure message is received
1 Power cycle the unit. To do this, remove and reconnect the AC mains
supply. If the unit has no AC mains supply, remove and reconnect the DC
RPS supply.
2 Check the command line interface (display logbuffer command)
to determine whether a thermal shutdown has occurred.
3 If no, return the unit:
If yes, check that:
■
The air vents are not obstructed.
■
The ambient temperatures and environmental conditions meet those
specified in Appendix C on page 127.
4 Power cycle the unit. If a further thermal shutdown occurs, and all
environmental conditions are satisfactory, return the unit to 3Com.
Error message indicating that the SFP transceiver is invalid
The switch has identified that the SFP does not meet the minimum
requirements for the switch and has disabled the port. To correct this
problem, completely remove the SFP and replace it with a 3Com
approved SFP. See “Approved 1000BASE-X SFP Transceivers” on page 47
and “Approved 100BASE-X SFP Transceivers” on page 48.
Error message indicating that the SFP transceiver is faulty
To correct this problem, completely remove the SFP and then reinsert it.
Alternatively, insert another identical SFP. If the problem persists, contact
3Com Technical Support.
Solving
Communication
Problems
If you experience communication problems with the switch, ensure that:
■
The switch IP address and management VLAN ID has been configured.
Solving Communication Problems
85
■
If the switch is separated from your management application by a
router, ensure that the default gateway IP address within the switch is
the same as the IP address of the router.
■
The switch’s IP address has been entered correctly in your network
management application (such as 3Com Network Director).
The following is a brief overview of IP addressing, and how to obtain a
registered IP address.
IP Addressing
To be managed correctly, each device on your network (for example a
switch or Hub) must have a unique IP address. IP addresses have the
format n.n.n.n where n is a decimal number between 0 and 255. An
example IP address is 192.168.100.8.
The IP address is split into two parts:
■
The first part (‘192.168.100’ in the example) identifies the network on
which the device resides
■
The second part (‘.8’ in the example) identifies the device within the
network
The natural subnet mask for this example is 255.255.255.0.
If your network has a connection to the external IP network, that is, you
access the Internet, you must apply for a registered IP address.
How do you obtain a registered IP Address?
The IP registration system ensures that every IP address used is unique; if
you do not have a registered IP address, you may be using an identical
address to someone else and your network will not operate correctly.
InterNIC Registration Services is the organization responsible for
supplying registered IP addresses. The following contact information is
correct at time of publication:
World Wide Web site: http://www.internic.net
If your IP network is internal to your organization only, that is, you do not
access the Internet, you may use any arbitrary IP address as long as it is
not being used by another device on your network. 3Com suggests you
86
CHAPTER 5: PROBLEM SOLVING
use addresses in the range 192.168.0.0 to 192.168.255.255 with a
subnet mask of 255.255.255.0.
These suggested IP addresses are part of a group of IP addresses that
have been set aside specially for use ‘in house’ only.
A device is connected to a Switch 5500-EI PWR or Switch 5500G-EI
but power is not being supplied
If power is not being supplied to a device connected to a Switch 5500
PWR, you should do the following checks:
■
Check that the device is compliant with the 802.3af standard ref. [18].
The 5500-EI PWR will supply power through the front panel ports to
802.3af compliant and many pre-standard devices.
■
Check that power budget for the switch has not been exceeded.
If the power budget has been exceeded, then by default, the powered
device connected to the Power over Ethernet port with the lowest
priority port will lose power. However, if all the devices connected to
the switch have equal priority levels, then the port with the highest
number will lose power.
By default, the switch will allow a device to receive power as long as
Power over Ethernet power supply has 18 watts spare in its power
budget. If this much power is not available, the device will not be
powered (unless it has a higher priority than existing powered ports)
and a PoE fault will be reported for that port. If enough power
subsequently becomes available, the port will be powered.
■
Check that the port has not had a power limit imposed on it.
The Switch 5500 PWR units do not provide PoE on the Gigabit SFP ports.
Solving Fabric
Formation
Problems
If you are having problems with correctly forming a fabric, first ensure
that Spanning Tree is enabled. If it is enabled, do the following:
1 Power off all units in the fabric.
2 Check all the cable connections in the fabric.
3 Check the ports have been enabled as fabric ports.
4 Power on all units in the fabric.

Bundled files with the extension NetMan.zip, can be used to upgrade
your switch using the 3Com Network Director Agent Update. Any
attempt to upgrade individual .web, .btm or .app files using 3Com
Network Director will fail. These files should be used to upgrade your
switch as described below.
Any attempt to upgrade the switch directly with xxxxxxxx.exe and
xxxxxxxxNetMan.zip will fail. The individual .web, .btm or .app
files should be used to upgrade your switch as described below.
Upgrading from the
Command Line
Interface
Introduction
This section describes how to upgrade files to your switch from the
Command Line Interface (CLI).
Before upgrading the software to your switch from the CLI, it is important
to check the contents of the flash to ensure that there is enough space to
download the new files.
The flash space needed for the new files is approximately 5.5 MB.
1 To check the contents of the flash, logon to your switch either via a telnet
connection or directly via the console to display the User View in the CLI
and enter the following:
dir unit1>flash:
A file list similar to the following is displayed:

fabric by entering:
dir
dir
dir
dir
dir
dir
unit2>flash:
unit3>flash:
unit4>flash:
unit5>flash:
unit6>flash:
unit7>flash:
The file list should contain one of each file type (.web, .def, .cfg
and .app).
3 Any additional files should be considered for deletion to allow maximum
space for downloading the new files. To delete a file from the list enter:
delete/unreserved unit1>flash:/filename
To delete files from the list for the remaining units in a fabric, replace
unit1 with unit2 (on the next line) and so on for each switch in the
fabric.
4 The /unreserved option will cause the file to be deleted from both the
flash and the recycle-bin. To check that deleted files have been removed
from the recycle-bin enter the following:
reset recycle-bin unit1>flash:/
If the recycle-bin is empty the following is displayed:
% File can’t be found “unitN>flash:/”
To check that deleted files have been removed from the recycle-bin for
the remaining units in a fabric, replace unit1 with unit2 and so on for
each switch in the fabric.
90
CHAPTER 6: UPGRADING SOFTWARE
The following steps enable you to backup each switch in the fabric:
1 The default configuration file must have the name 3ComOScfg.def.
This file is only used if there is no active configuration file (.cfg) in the
flash file system. The default configuration file is the same for every
Switch 5500 of the same type (i.e Switch 5500 28-port) and is different
to the file for a Switch 5500 of a different type (i.e Switch 5500 52-port).
A sample default configuration file is provided by factory default with the
switch and is not supplied in this upgrade.
Enter the following command:
more 3comoscfg.def
The display similar to the following shows on the first line of the file:
#28-port 3com version 3.1.4
This file is infrequently changed, so the version number may not match
the application software version number.
The default configuration file can be created by saving the configuration
and renaming the xxx.cfg file as 3ComOScfg.def.
To back up the default configuration file on each switch in the fabric,
enter:
copy unit1>flash:/3ComOScfg.def
unit1>flash:/030100cfg.def
Replace unit1 with unit2 and so on for each switch in the fabric.
2 The active configuration file can been given any name, provided it ends in
the extension .cfg. 3Com recommends that each fabric is given a
unique configuration file name so that when the file is saved to an
external TFTP server, it is clear which fabric the file belongs to.
To back up the active configuration file on each switch in the fabric,
enter:
copy unit1>flash:/3ComOScfg.cfg
unit1>flash:/030100cfg.cfg
Replace unit1 with unit2 and so on for each switch in the fabric.
3Com recommends that you save the active configuration file for each
switch in the fabric is also saved to an external storage device. To save the
active configuration file to a TFTP server in User View enter:
tftp aaa.aaa.aaa.aaa put unit1>flash:/3ComOScfg.cfg
3ComOScfg_1.cfg
Upgrading from the Command Line Interface
91
(where aaa.aaa.aaa.aaa is the IP address of the TFTP server)
Replace unit1 with unit2 and _1.cfg with _2.cfg and so on for
each switch in the fabric.
3 The Web user interface file and the application file must be the same on
all switches in the fabric. It is not necessary to backup these files because
they will have a new version number.
TFTP
To upgrade software to your switch via TFTP do the following:
1 To download the application file, enter:
tftp aaa.aaa.aaa.aaa get s4a03_01_04s56.app
(where aaa.aaa.aaa.aaa is the IP address of the TFTP server)
s4a indicates the switch filename, see Table 24 for further details:

2 To download the Web user interface file, enter:
tftp aaa.aaa.aaa.aaa get s4h01_04.web
3 To download the default configuration file, enter
tftp aaa.aaa.aaa.aaa get 3ComOScfg.def
4 To download the bootrom file, enter:
tftp aaa.aaa.aaa.aaa get s4e01_04.btm
The bootrom firmware may not require upgrading for every software
upgrade. To display the bootrom firmware version in any view enter:
display version
The following should be displayed:
Bootrom version is 1.04
92
CHAPTER 6: UPGRADING SOFTWARE
The number 1.04 will match the version number in the bootrom file,
which is 01_04. If the version number of the file matches the displayed
version, there is no need to download the bootrom (.btm) file.
File Distribution
The following commands enable you to distribute your downloaded files
to the remaining switches in the fabric:
1 To copy the new software file to each switch in the fabric, enter the
following from User View:
copy unit1>flash:/s4a03_01_04s56.app unit2>flash:/
Replace unit2 with unit3 and so on for each switch in the fabric.
2 To copy the new default configuration file to each switch in the fabric,
enter:
copy unit1>flash:/3ComOScfg.def unit2>flash:/
Replace unit2 with unit3 and so on for each switch in the fabric.
3 To copy the new Web user interface file to each switch in the fabric,
enter:
copy unit1>flash:/s4e01_04.web unit2>flash:/
Replace unit2 with unit3 and so on for each switch in the fabric.
4 To copy the new Bootrom firmware file to each switch in the fabric, enter:
copy unit1>flash:/s4e01_04.btm unit2>flash:/
Replace unit2 with unit3 and so on for each switch in the fabric.
Command Line Interface Switch Setup
1 To set the switch to boot from the new software you have downloaded,
enter the following:
boot boot-loader unit1>flash:/s4a03_01_04s56.app
To set the remaining switches in the fabric to boot from the new
software, replace unit1 with unit2 and so on for each switch in the
fabric.
2 To set the switch to load the new bootrom firmware, enter:
boot bootrom unit1>flash:/s4e01_04.btm
Upgrading from the Command Line Interface
93
To set the remaining switches in the fabric to load the new bootrom
firmware, replace unit1 with unit2 and so on for each switch in the
fabric.
3 You will now need to reboot the fabric for the changes to take effect. The
switch will upgrade the bootrom firmware and boot from the specified
software .app file.
The files that you have saved in the backup phase should be deleted once
the upgrade has completed successfully.
