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.

10BASE-T/

100BASE-TX Ports

The Switch 5500 has 24 or 48 auto-negotiating 10BASE-T/100BASE-TX ports configured as Auto MDIX (cross-over). These ports automatically provide the appropriate connection. Alternatively, you can manually set these ports to 10BASE-T half duplex, 10BASE-T full duplex, 100BASE-TX half duplex or 100BASE-TX full duplex. The maximum segment length is

100 m (328 ft) over Category 5 twisted pair cable.

1000BASE-X SFP Ports

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 which auto-neogtiation is mandatory) 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.

Unit LED

The Unit LED is a seven segment display visible on the front of the Switch.

The Unit LED can be used to indicate the unit number in a fabric, POST test ID and software upgrade information. In the unlikely event of a hardware fault occurring, the Unit LED may be used to help diagnose the problem. For information on using the Unit LED for problem solving, see

“Solving Problems Indicated by LEDs” on page 62

Connecting a Redundant Power Supply

Connecting a

Redundant Power

Supply

The Switch 5500 has an unearthed 48V DC Redundant Power Supply socket.

WARNING: The installation of the Redundant Power Supply (RPS) should only be carried out by properly trained and qualified personnel.

WARNING: These instructions must be read in conjunction with the RPS flyer and the safety and installation instructions supplied with your RPS.

WARNING: When powering any Switch 5500 from an RPS, the unit must be earthed (grounded). This can be achieved 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. You must ensure that the earth connection is made before connecting the DC supply from the RPS.

WARNING: Any RPS must be approved as an unearthed 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 given in

Appendix C

on

page 105

.

The Switch 5500 can be powered in three different ways:

■

AC Mains only — does not offer any power redundancy. If the AC mains supply or the AC power supply fail, the Switch will power off.

■

■

AC Mains and Unearthed 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 an environment where only DC power is available.

The RPS provides two main benefits to the customer:

■

■

Power Redundancy — if a Switch is powered from the mains supply unit, a failure of the internal power supply will cause the Switch to fail.

This can be overcome by connecting both the AC and DC RPS supplies to the Switch. Additional redundancy can also be added to the DC power by using (N+1) DC power supplies to further increase the availability of the system.

Uninterruptible Power — the system allows easy connection and maintenance of batteries to the RPS shelf to further increase the availability of the system.

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 which can house from one to six rectifiers, a

Distribution Module and a Management Module.

The RPS generates 48V DC power using power supply units (or rectifiers).

The outputs of the rectifier(s) are connected together so that the total

48V power available can be increased by adding additional rectifiers. For example, three 1500W rectifiers can provide up to 4500W. Hot removal or insertion of a rectifier will not affect the 48V DC output voltage.

Table 7 shows an example of the total power available from a number of

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 a number of circuit breakers and connection terminals for the positive (common) and negative 48V outputs. Each Switch 5500 must be individually connected to a circuit breaker terminal.

A battery can also be connected to battery terminals prior to the DC power distribution to provide uninterrupted power in order to protect against the loss of AC mains power.

Placing Units On

Top of Each Other

If the Switch units are free-standing, up to eight units can be placed one on top of the other. If you are mixing a variety of SuperStack ® units, the smaller units must be positioned at the top.

If you are placing Switch units one on top of the other, you must use the self-adhesive rubber feet supplied. Apply the feet to the underside of each Switch, sticking 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

The following sections describe how to get your Switch 5500 powered-up and ready for operation.

Powering-up the

Switch 5500

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 one minute.

Checking for Correct

Operation of LEDs

During the Power On Self Test, all ports on the Switch are disabled and the LEDs light. The PWR LED will flash green during the POST.

When the POST has completed, check the PWR LED to make sure that

your Switch is operating correctly. Table 10

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.

SFP Operation

The following section 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.

You will need to install an SFP transceiver if you wish to create an XRN

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.

Removing an SFP

Transceiver

If you wish to remove the transceiver (it is not necessary to power-down your Switch):

1 Disconnect the cable from the transceiver.

2 Move the wire release lever downwards until it is pointing toward you.

3 Pull the wire release lever toward you to release the catch mechanism; the transceiver will then easily slide out.

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 11 .

on

page 48

.

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

When you configure the IP information, the Switch remembers the 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, or

■

■ you want to remove the risk of the IP address ever changing, or 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 configure the Switch

IP information manually. This makes management simpler and more reliable as it is not dependent on a DHCP or BootP server, and eliminates the risk of the IP address changing.

To manually enter IP information for your Switch, work through the

“Manually Configuring IP Information” section on page 35 .

Automatic IP Configuration via DHCP

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.

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 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 Configuration Guide on the CD-ROM that accompanies your Switch or 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 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 the Switch is not allocated with an automatic IP addresss, 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. Work through the “Viewing Automatically Configured IP

Information” section on page 41 .

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 30

.

For detailed information about the specific web interface operations and command line interface commands and problem solving, refer to the

“SuperStack 4 Switch Command Reference Guide” on the CD-ROM that is supplied with the Switch or on the 3Com Web site.


Manually Configuring IP Information

35

Manually

Configuring IP

Information

You can manually configure the Switch IP information in the following ways:

■

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).

■

Connecting to a front panel port — connect 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).

Connecting to the

Console Port

To set up your Switch manually you can make a connection to the console port, (this example describes a local connection to the console port, rather than 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.

■

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).

Using 3Com Network

Director

You can use the 3Com Network Director application (available from the

3Com website) 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 will auto-discover the new Switch and display the IP information that has been automatically allocated to the Switch.

Most DHCP and BootP 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 or BootP server.

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

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.) For further information on

connecting via the console port see “Connecting the Workstation to the

Switch” on page 36

.

Viewing IP Information via the Console Port

You are now ready 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.

Setting Up

Command Line

Interface

Management

This section describes how you can set up command line interface management using a local console port connection or over the network.

User Interface

Overview

User interface configuration is provided by the Switch to configure and manage the port data. There are two types of user interfaces:

AUX User Interface — used to log in to your Switch via the console port.

A fabric can have up to eight AUX user interfaces.

VTY User Interface — used to Telnet to the Switch. The Switch can have up to five VTY user interfaces.

CLI Management via the Console Port

To manage a Switch using the command line interface via the local console port connection:

1 Ensure you have connected your workstation to the console port correctly

as described in “Connecting to the Console Port”

on

page 35 .

2 Your Switch is now ready to continue being managed and/or configured through the CLI via its console port.

CLI Management over the Network

To manage a Switch using the command line interface over a network using Telnet:

1 Ensure you have already set up the Switch with IP information as described in

“Methods of Managing a Switch” on page 30 .

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 protocol is installed.

3 Check 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


If you get an error message, check that your IP information has been entered correctly and the Switch is powered up.

4 To open a Telnet session via the DOS prompt, enter the IP address of the

Switch that you wish to manage in the following format:

>telnet xxx.xxx.xxx.xxx


Setting Up Command Line Interface Management using SSH

How To Interconnect Units

Guidelines For Interconnecting Units

■

Unit Numbering within the Fabric

The procedure for creating a Fabric with the Switch 5500-SI units is the same procedure as that for creating a Fabric with the Switch 5500-EI units.

How To

Interconnect Units

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 14 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 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 for Management”

or that you are using a console cable connected to the console port to set up and allocate IP addresses and so on.

3Com recommends that you do not physically connect the cables on your

Fabric ports until you have carried out the initial configuration of the

Fabric ports as detailed below.

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 14

) to operate in Fabric mode using the following CLI command. From the

System View enter fabric-port gigabitethernet 1/0/51

enable

, for example.

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 14

.

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 17

on

page 60 .

This ensures that in the event of a unit failure within the Fabric, the Fabric will continue working and no “Fabric split” will occur.

5 Save all configuration settings. From the User View, enter the save command to save the configuration to your Switch.


Guidelines For Interconnecting Units

59

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 5500G Switch units) 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).

■

When a port is operating in XRN Fabric mode it will no longer be configurable in the normal way, that is, you cannot control port features such as auto-negotiation, VLANs, static addresses, STP,

Aggregated Links, Resilient Links, and so on. However, it is possible to specify the Fabric VLAN.

For a detailed description of how XRN Technology operates and implementation guidelines, please refer to the Configuration Guide on the CD-ROM that accompanies your Switch.

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.

■

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.

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.


Solving Hardware Problems

63

Auto-negotiation problems will occur with 10BASE-T or 100BASE-T where auto-negotiation is disabled and incorrect cables are being used

(cross-over or straight)

Auto-negotiation problems will occur with fiber if:

■

■

The Receiver (RX) and Transceiver (TX) cable connectors are swapped

Fibers are broken

■

Auto-negotiation differs at either end (a link appears at the ‘fixed’ end and not at the auto-negotiation end)

Solving Hardware

Problems

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.

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

.

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 31 .

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.

If you experience communication problems with the Switch, ensure that:

■

The Switch IP address and Management VLAN ID has been configured.


Solving Communication Problems

65

■

■

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

Problems

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.

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.

Upgrading from the

Command Line

Interface

This section describes how to upgrade files to your Switch from the

Command Line Interface (CLI).

Introduction

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:

Directory of unit1>flash:/

0 -rw714784 Apr 02 2005 01:36:16 s4h03_01_00.zip

1 -rw11043 Apr 02 2005 01:37:17 3ComOScfg.def

15367 KB total (10215 KB free)

2 You can check the contents of the flash for the remaining units in the fabric by entering:

dir unit2>flash: dir unit3>flash: dir unit4>flash: dir unit5>flash: dir unit6>flash: dir unit7>flash:

The file list should contain one of each file type (.zip, .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


Upgrading from the Command Line Interface

69

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.

The following steps enable you to backup each Switch in the fabric:

1 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 To back up the active configuration file on each Switch in the fabric, enter:

copy unit1>flash:/3ComOScfg.cfg unit1>flash:/030100cfg.cfg


3 To back up the Web user interface file on each Switch in the fabric, enter:

copy unit1>flash:/s4h03_01_00.zip unit1>flash:/030100http.zip
