Time and items required for removal and installation
The removal or installation procedure for each blade takes less than 10 minutes. Removing and restoring
transceivers and cables may take longer depending on how many must be changed. The following items
are required for the blade and filler panel replacement:
v Electrostatic discharge (ESD) grounding strap
v Workstation computer
v Replacement blade or filler panel
v #1 Phillips screwdriver
v SFP, SFP+, or SFP28 transceivers (as needed)
v Optical and copper cables (as needed)
Note: For information about the transceivers that are qualified for this device, refer to “Installing
Transceivers and Cables” on page 65.
Removing a blade
Before you begin
v Before removing any cables from a blade, note the cable order (identify each cable by its physical
port).
v It is a good practice to create a table of cable to port mapping for reference.
v If multiple blades are being replaced, replace one blade at a time.
About this task
Use the following steps to remove a port or extension blade from the unit while system power is on. This
procedure is applicable for all the port and extension blades supported on the device.
Procedure
1. Remove the chassis door.
2. Check the blade power and status LEDs and port status LEDs on the front of each blade to identify
any possible problems.
3. Before replacing a blade, establish a Telnet or console connection to determine a failure and verify
operation after replacement. Use the
switchShow and slotShow commands to view the status of the
blades.
4. Check for adequate cable slack. Ensure there is plenty of cable slack to remove a blade without cable
obstruction.
5.
Ensure that the part number on the unit being replaced matches the replacement part number. The
chassisShow
command displays information about the blades, including part numbers
(xx-xxxxxxx-xx), serial numbers, and additional status.
6. Ensure that traffic is not flowing through the blade (port status LED should be off) prior to
disconnecting cables.
7. Disconnect all cables and remove transceivers from the blade.
8. If removing an extension blade, perform the following steps:
a. Delete all fciptunnel configurations using the portcfg fciptunnel slot/vePort delete command.
b. Delete all IP Routes defined on the blade to be removed using the portcfg iproute delete
command.
c. Delete all IP interfaces (IPIFs) defined on the blade using the portcfg ipif slot/geX delete
command.
d. If logical switches are used on the switch, move all blade ports back to the default logical switch.
Refer to the
lscfg
command in the Fabric OS Command Reference for details.
