Guideline for Installing a Cross Bar Fabric Module
Note : We recommend that you follow this guideline while installing the cross bar fabric module.
Depending on the number of the crossbar fabric modules in the chassis configuration, the following slot
number should be assigned on the IBM c-type SAN Device :
Number of Crossbar Fabric Modules
2
3
4
5
6
Note :
In an IBM c-type chassis with the 24/10-Port SAN Extension Module, the chassis must have at least one
online crossbar fabric switching module in the slots 1 to 5 at any point of time
In an IBM c-type chassis with the 24/10-Port SAN Extension Module, if crossbar (xbar) fabric switching
modules 5 and 6 are online, and you want to power down or replace module 6 nondisruptively, you have
to power down/out-of-service xbar module 5 first, followed by power down/out-of-service and replace
the xbar module 6.
Installing a Crossbar Fabric Module
Before you begin
You must follow ESD protocols, including the following:
1. You must wear a grounded ESD wristband (or other personal grounding device) whenever you handle
the electronic modules outside the grounded chassis.
2. You must carry electronic modules by only their covered edges or handles. Do not touch their
electronic components.
3. Whenever a module is outside a grounded chassis, place it flat on an antistatic surface or in an
antistatic bag. Never lean the module on anything nor place anything else on top of the module nor
lean anything on the module.
• Verify that the chassis is grounded.
• Verify that you have the following tools and equipment:
a. ESD wrist strap (or other personal grounding device).
b. Number 1 Phillips torque screwdriver.
c. Manual torque screwdrivers are recommended. Be sure to never exceed the recommended
torque setting for the screw that you are working with.
• Ensure that sufficient quantity of Crossbar Fabric-3 Switching Modules (6 modules are supported in
a IBM SAN c-type Director switches) are available for replacing the current Crossbar Fabric Switching
Modules in the switch.
