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 154 or "Cold-swap replacement"
on page 156.
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.
