Replacing an interface module

CAUTION

It is recommended that modules be disabled through the CLI before removal from the chassis. If

the operator wishes to remove the module without first disabling the module, the Enhanced Hot

Swap capability in software Release 03.2.00 and later supports this procedure for the FSX 800

and FSX 1600 chassis. Enhanced Hot Swap (that is, no CLI disable) should be performed during

a maintenance window. On rare occasions, an Enhanced Hot Swap may result in a software

reload of the system. The likelihood of this event is very low.

It is important to wait a minimum of 10 seconds between the removal and insertion of a line

module. Re-insertion of a line module less than 10 seconds after the removal of a line module

may result in the line module not being properly recognized.

Removing an interface module

To remove an interface module, first perform the steps in section “Before removing an interface

module” on page 112, then complete the following steps.

1. Put on the ESD wrist strap and ground yourself by inserting the plug into the ESD connector

located in the lower right corner of the chassis front.

2. Use the #2 Phillips-head or flathead screwdriver to loosen the two screws on the ends of the

module.

3. Pull the card ejectors towards you, and away from the module front panel. This action unseats

the module from the backplane.

4. Pull the module out of the chassis, and place in an anti-static bag for storage if desired.

5. If you plan to replace the removed module with a different type of module, you must first

remove the module configuration. To do so, enter the no module <slotnum> command at the

global CONFIG level of the CLI, then save the configuration to flash memory. For example,

Brocade(config)# no module 4

Brocade(config)# exit

Brocade# write mem

NOTE

If you attempt to insert a module of a different type without first removing the previous module

configuration, the system will display an error message.

6. Install a new module in the slot. For information about performing this task, refer to “Installing

a new interface module”.

CAUTION

If you do not install a module in a slot, you must keep the slot panel in place. If you run the

chassis with an uncovered slot, the system will overheat.
