Removing the WWN card and bezel
About this task
Two WWN cards located behind the WWN bezel. As you are facing the bezel on
the non-port-side of the device, WWN 1 is located on the left side, and WWN 2 is
on the right. When cards have been determined faulty and the replacement WWN
cards have been received, complete the following steps to remove the bezel and
faulty WWN cards.
Note: Unless the device is powered down and not operational, do not perform
these steps without first performing procedures under either “Hot-swap
replacement” on page 153 or “Cold-swap replacement” on page 154.
Procedure
1. Remove the two screws from the WWN bezel on the back of the device using a
Phillips screwdriver. Pull the bezel away from the chassis and set it aside. The
ends of both WWN card assemblies with pull tabs are now visible.
2. Unscrew the captive screw for the WWN card assembly using a Phillips
screwdriver until the assembly releases from chassis.
3. Grasp the pull tab for a WWN card assembly and gently pull to release the
assembly from backplane connector. Carefully slide the card assembly out from
the chassis slot. Use both hands to support the card assembly along its length
as you remove it from the slot.
