WARNING: RJ-45 Ports. These are shielded RJ-45 data sockets. They
cannot be used 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.
Either shielded or unshielded data cables with shielded or unshielded
jacks can be connected to these data sockets.

CHAPTER 1: INTRODUCING THE SUPERSTACK 3 SWITCH 3870
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
speed, duplex and flow control modes of a link are automatically
detected to provide the highest available bandwidth with the link partner.
Alternatively, auto-negotiation can be disabled. These ports can be
manually configured 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 as auto-negotiation is mandatory in
the 1000 Mbps standard. If auto-negotiation is disabled, Auto MDIX
cannot function and the ports are fixed as MDIX (cross-over) mode.
If auto-negotiation is disabled on a 1000 Mbps port, the speed will drop
to the highest available speed. By default this is 100 Mbps.
Dual Personality SFP
Ports
The 4 Dual Personality SFP (Small Form Factor Pluggable) ports support
fiber Gigabit Ethernet short-wave (SX), long-wave (LX) and long-haul
(LH70) 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 SFP ports are capable of auto-negotiating flow control. 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 and the flow control setting can be manually configured.
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 will need to connect an RJ-45 to DB9 converter cable to a
standard null modem cable in order to connect a terminal.
The standard null modem cable is set to autobaud (up to a maximum of
19,200 baud), 8 data bits, no parity and 1 stop bit.

The Switch 3870 is suited for use in an internal wiring closet, a network
room, or telecommunications room, where it can be mounted in a
standard 19-inch equipment rack, or free-standing.
CAUTION: Ensure that the ventilation holes are not obstructed.
To ensure this product provides optimum performance, high speed fans
are used to provide ventilation. These fans have a high audible output
while running at full speed. The Switch 3870 is designed to reduce the
fan speed shortly after power on (if thermal conditions allow) which will
also reduce the fan noise generated.
When deciding where to position the Switch, ensure that:
■
Cabling is located away from:
■
sources of electrical noise such as radios, transmitters and
broadband amplifiers.

power lines and fluorescent lighting fixtures.
■
The Switch is accessible and cables can be connected easily.
■
Water or moisture cannot enter the case of the Switch.
■
Air flow is not restricted around the Switch or through the vents in the
side of the Switch. 3Com recommends that you provide a minimum of
25 mm (1 in.) clearance.
■
Air temperature around the Switch does not exceed 40 °C (104 °F).
If the Switch is installed in a 19-inch rack or closed assembly its local air
temperature may be greater than room ambient temperature.
Rack-mounting
■
The air is as free from dust as possible.
■
The Switch is situated away from sources of conductive (electrical)
dust, for example laser printers.
■
The unit is installed in a clean, air conditioned environment.
■
The AC supply used by the Switch is separate to that used by units
that generate high levels of AC noise, for example air conditioning
units.
■
No more than four Switch units are placed on top of one another, if
the units are free-standing.
The Switch 3870 is 1U high and will fit in most standard 19-inch racks.
CAUTION: Disconnect all cables from the Switch before continuing.
Remove all self adhesive pads from the underside of the Switch if they
have been fitted.
CAUTION: If you use a shelf or support ensure that it will not obstruct
the air flow through the side panels of the Switch.
To rack-mount your Switch:
1 Place the Switch the right way up on a hard flat surface, with the front
facing towards you.
2 Locate a securing bracket over the mounting holes on one side of the
Switch, as shown in Figure 4.

The Power-up Sequence
The Power-up
Sequence
Powering-up the
Switch 3870
23
The following sections describe how to get your Switch 3870
powered-up and ready for operation.
Use the following sequence of steps to power-up the Switch.
1 Plug the power cord into the power socket at the rear 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 1 minute.
Checking for Correct
Operation of LEDs
During the Power On Self Test, all ports on the Switch are disabled and
the LEDs light in a rapid sequence.
When the POST has completed, check the Unit Status to make sure that
your Switch is operating correctly. Table 7 shows possible colors for the
LED.
Table 7 Unit Status Colors
Color
State
Green
The Switch is powered-up and operating normally.
Yellow
The Switch has failed its Power On Self Test (POST).
Off
The Switch is not receiving power.
If there is evidence of a problem, see “Solving Problems Indicated by
LEDs” on page 46 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.
Connecting a
Redundant Power
Supply
You can connect a SuperStack 3 Advance Redundant Power System to
the Switch. This unit, which is also known as RPS, is designed to maintain
the power to your Switch if a power supply failure occurs.
For normal redundancy, the unit requires a Type 3 Power Module (part
number 3C16075)
DUA1745-0AAA03.book Page 24 Friday, April 8, 2005 12:34 PM
24
CHAPTER 2: INSTALLING THE SWITCH
For full redundancy, the unit requires two Type 3 Power Modules
combined using a Type 3 Y-Cable (part number 3C16077).
WARNING: If you are connecting the Switch to a Type 3 Power Module,
read the Safety Information section in the Type 3 Power Module User
Guide.
CAUTION: The Switch can only use a SuperStack Advance Redundant
Power System output.
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 cable
(MDIX).
The Auto-MDIX feature only operates when auto-negotiation is 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 8.
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.).

SFP Operation
25
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. If you do not,
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.
SFP Operation
The following sections describes how to insert an SFP transceiver into an
SFP port.
SFP transceivers are hot-insertable and hot-swappable. You can remove
them from and insert them into any SFP port without having to power
down the Switch.
Approved SFP
Transceivers
The following list of approved SFP transceivers is correct at the time of
publication.
■
3CSFP91 SFP (SX)
■
3CSFP92 SFP (LX)
■
3CSFP97 SFP (LH70)
To access the latest list of approved SFP transceivers for the Switch on the
3Com Corporation World Wide Web site, enter this URL into your
internet browser:
http://www.3com.com
Inserting an SFP
Transceiver
To be recognized as valid, the SFP transceiver must have the following
characteristics:
■
1000BASE-SX, 1000BASE-LX or 1000BASE-LH70:
■
1000BASE-SX SFP transceiver
Use this transceiver to connect the Switch directly to a multimode
fiber-optic cable.
■
1000BASE-LX SFP transceiver
DUA1745-0AAA03.book Page 26 Friday, April 8, 2005 12:34 PM

CHAPTER 2: INSTALLING THE SWITCH
Use this transceiver to connect the Switch directly to a single-mode
fiber-optic cable or to multimode fiber using a conditioned launch
cable.
■
1000BASE-LH70 SFP transceiver
Use this transceiver to connect the Switch directly to a single-mode
fiber-optic cable.
If the SFP transceiver is faulty, it will not operate within the Switch. See
“Solving Hardware Problems” on page 47.
3Com recommends that you only use SFPs supplied by 3Com. If the SFP
transceiver is invalid it will not be recognized by the Switch.
Use the following sequence of steps to activate the SFP ports:
1 The SFP transceiver is keyed and there is only one way in which it can be
installed correctly. It is not necessary to power-down your Switch.
2 Hold the transceiver so that the connector is toward you and the product
label is visible. Ensure the wire release lever is closed (in the upright
position).
3 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.
4 Remove the plastic protective cover if fitted.
CAUTION: The dual personality ports on the Switch 3870 enable you to
activate an RJ-45 port or an SFP port or a mixture of both (for example,on
the 24 Port Switch, you can activate the RJ-45 ports 21 and 22 and the
SFP ports 23 and 24 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 will take priority.

SETTING UP FOR MANAGEMENT
Your Switch can operate in its default state, that is, you can install it and
it will work straight away (plug-and-play). However, to make full use of
the features offered by the Switch, and to change and monitor the way it
works, you have to access the management software that resides on the
Switch. This is known as managing the Switch.
Managing the Switch can help you to improve the efficiency of the
Switch and therefore the overall performance of your network.
This chapter explains the initial set up of the Switch and the different
methods of accessing the management software to manage a Switch. It
covers the following topics:

CHAPTER 3: SETTING UP FOR MANAGEMENT
This section gives an overview of what you need to do to get your Switch
set up and ready for management when it is in its default state. The
whole setup process is summarized in Figure 6. Detailed procedural steps
are contained in the sections that follow. In brief, you need to:
■
Configure IP information manually for your Switch or view the
automatically configured IP information
■
Prepare for your chosen method of management

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 default
users and changing default passwords, see “Default Users and
Passwords” on page 43.
IP Configuration
You can use one of the following methods to allocate IP information to
your Switch (essential if you wish to manage your Switch across the
network).
Manual IP Configuration
You can choose to configure the IP information yourself. The Switch
remembers the information that you enter until you change it again or
set the configuration method to Automatic.
You should use the Manual IP configuration method if:
■
you do not have a DHCP server on your network, or
■
you want to remove the risk of the IP address ever changing, or
■
your DHCP 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 configure the Switch
IP information manually. This makes management simpler and more
reliable as it is not dependent on a DHCP server, and eliminates the risk of
the IP address changing.
If you wish to manually enter IP information for your Switch, work
through the “Manually Configuring IP Information” section on page 33.
Automatic IP Configuration
By default the Switch tries to configure itself with IP information without
requesting user intervention. It tries to obtain an IP address from a DHCP
server on the network.
It takes up to 5 minutes for your Switch to obtain an IP address after it
has been powered up.
When using automatic IP configuration it is important that the IP address
of the Switch is static, otherwise you will not know what the IP address is
and it will be difficult to manage. Most DHCP servers allow static IP
DUA1745-0AAA03.book Page 32 Friday, April 8, 2005 12:34 PM
32
CHAPTER 3: SETTING UP FOR MANAGEMENT
addresses to be configured so that you know what IP address will be
allocated to the Switch. Refer to the documentation that accompanies
your DHCP server.
For a detailed description of how automatic IP configuration operates,
please refer to the Implementation Guide on the CD-ROM that
accompanies your Switch or on the 3Com Web site.
You should use the automatic IP configuration method if:
■
your network uses DHCP to allocate IP information, or
■
flexibility is needed. If the Switch is re-deployed onto a different
subnet, it will automatically reconfigure itself with an appropriate IP
address, instead of you having to manually reconfigure the Switch.
If you use the automatic IP configuration method, you need to discover
the automatically allocated IP information before you can begin
management. Work through the “Viewing Automatically Configured IP
Information” section on page 36.
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 39.
For detailed information about the specific web interface operations and
command line interface commands and problem solving, refer to the
“Management Interface Reference Guide” on the CD-ROM that is
supplied with the Switch or on the 3Com Web site.

Manually Configuring IP Information
Manually
Configuring IP
Information
Connecting to the
Console Port
33
You can manually configure the Switch IP information in the following
way:
■
Connecting to the console port — connect a workstation using a
console cable to the console port of the Switch. You can then
manually enter IP information using the command line interface (CLI).
To set up your Switch manually you can alternatively make a connection
to the console port (this example describes a local connection to the
console port, rather than a remote one via a modem). You can do this
whilst the Switch is offline, that is, before you connect the Switch to a
network, or whilst the Switch is online, that is, connected to a network.
Pre-requisites
■
A workstation with terminal emulation software installed, such as
Microsoft Hyperterminal. This software allows you to communicate
with the Switch via the console port directly, or through a modem.
■
Documentation supplied with the terminal emulation software.
■
A suitable cable:
■
■
■
An RJ-45 to DB9 converter cable.
A standard null modem cable — if you are connecting directly to
the console port, or
A standard modem cable — if you are connecting to the console
port using a modem.
You can find pin-out diagrams for both cables in Appendix B on page 69.
■
You need to have the following so that you can manually set up the
Switch with IP information:
■
IP address
■
subnet mask
■
default gateway

prompts you to enter IP information.
4 Enter the IP address, subnet mask, and gateway IP address for the Switch.
The screen displays a summary of the information entered.
If using the gettingStarted command you will then be prompted to
enter system information, change passwords, and then given the option
to carry out advanced configuration.
The initial set up of your Switch is now complete and the Switch is ready
for you to set up your chosen management method. See “Methods of
Managing a Switch” on page 39.
If you do not intend to use the command line interface via the console
port to manage the Switch, you can logout, disconnect the serial cable
and close the terminal emulator software.

CHAPTER 3: SETTING UP FOR MANAGEMENT
Viewing
Automatically
Configured IP
Information
Using 3Com Network
Supervisor
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 Supervisor — this application will auto-discover
the Switch and display the automatically allocated IP information
assigned to the Switch.
■
Connecting to the Console Port — connect a workstation using a
console cable to the console port of the Switch. You can then view the
IP information automatically assigned to the Switch using the
command line interface (CLI).
You can use the 3Com Network Supervisor application provided on the
CD-ROM that accompanies your Switch 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 Supervisor and run the Auto-discovery wizard.
3Com Network Supervisor will auto-discover the new Switch and display
the IP information that has been automatically allocated to the Switch.
Most DHCP servers allow static IP addresses to be configured so that you
know what IP address the Switch will be given. Refer to the
documentation that accompanies your DHCP server.
If your network does not have a DHCP server, the workstation running
3Com Network Supervisor must be on the same subnet as the Switch,
because Auto-IP addresses are non-routable.
Connecting to the
Console Port
Alternatively, you can view the automatically configured IP information
via 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 one via a modem.)
Pre-requisites
■
A workstation with terminal emulation software installed, such as
Microsoft Hyperterminal. This software allows you to communicate
with the Switch via the console port directly, or through a modem.

For Technical Support information, see Appendix D.
DUA1745-0AAA03.book Page 46 Friday, April 8, 2005 12:34 PM
46
CHAPTER 4: 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 Unit 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.
The Unit LED will not light if the Switch 3870 is a standalone unit. If the
Switch 3870 is part of a stack, the Unit ID will be shown.
The Power/Self Test 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. 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 Power/Self Test LED lights yellow for about ten
seconds after which it starts flashing green.
On powering-up, the Power/Self Test LED remains yellow
This indicates one of the following:
■
A port has failed and has been automatically disabled. You can verify
this by checking that the Port Status LED is flashing Green/Yellow
(fast). This could be due to a loop back failure. If a port fails the Switch
passes its Power On Self Test and continues to operate normally.
DUA1745-0AAA03.book Page 47 Friday, April 8, 2005 12:34 PM
Solving Hardware Problems
47
■
An internal fan has malfunctioned. If a fan has stopped spinning,
power off the unit and check the air vents for obstructions. If this
situation occurs, the Fault LED will light red.
■
The internal PSU has failed and power is being supplied by an external
Redundant Power Supply (RPS). Although the Switch has a fault it will
continue to operate normally.
On Powering up, the Power/Self Test LED lights yellow for about ten
seconds after which it starts flashing green. This is normal and does not
indicate any of the above conditions.
A Port Status LED is flashing green/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 Status LED for the port 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.
Auto-negotiation problems will occur with 10BASE-T, 100BASE-TX or
1000BASE-T where auto-negotiation is disabled and incorrect cables
are being used (cross-over or straight).
Solving Hardware
Problems
In the rare event of your Switch unit experiencing a hardware failure,
refer to the list of suggested solutions below.
An expansion module is installed and the unit will not power up
Ensure that the expansion module is fully seated in the slot and the
connectors are engaged so that the securing screws can be tightened.
DUA1745-0AAA03.book Page 48 Friday, April 8, 2005 12:34 PM
48
CHAPTER 4: PROBLEM SOLVING
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.
Should one or more fans fail within the Switch, a warning message will
be generated in the following ways:
■
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 system summary 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. The device mimic will also
display red flashing fan icons.
For further information about RMON, refer to “Chapter 7: Status
Monitoring and Statistics” in the Switch Implementation Guide supplied
in PDF format on the CD-ROM that accompanies the Switch.
If a fan failure warning message is generated:
1 Power off the unit.
2 Check that the air vents are not obstructed.
3 Power cycle the unit. To do this, remove and reconnect the AC mains
supply.
4 If a fan fail trap is still received, return the unit.
Unit fails or SNMP thermal shutdown trap is received
1 Power cycle the unit. To do this, remove and reconnect the AC mains
supply.
2 Check the command line interface (system summary 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.
DUA1745-0AAA03.book Page 49 Friday, April 8, 2005 12:34 PM
Solving Communication Problems
■
49
The ambient temperatures and environmental conditions meet those
specified in Appendix C.
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 SFP Transceivers” on page 25.
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 has been configured.
■
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 (for example 3Com Network Supervisor).
The following is an 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
DUA1745-0AAA03.book Page 50 Friday, April 8, 2005 12:34 PM
50
CHAPTER 4: PROBLEM SOLVING
■
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
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.
