Replacing the WWN Card
The WWN card is located on the non-port side of the chassis, underneath the
WWN bezel.
Before replacing the WWN card, verify the necessity of the replacement with the
switch support personnel. The Core Switch 2/64 WWN card is highly reliable and
contains redundant components. In the unlikely event that the WWN card does
fail, the Core Switch 2/64 can continue operating due to the high availability
design until the WWN card is replaced, provided the Core Switch 2/64 does not
go through a power cycle.
If a replacement WWN card is ordered, replacement instructions are provided
with the new card.
For Fabric OS v4.0.2 and earlier, replacing the WWN card requires root access to
the Core Switch 2/64. In addition, all software license keys must be replaced when
a new WWN card is installed.

by screws, and the other is held onto the chassis by the pressure of the bezel against a
pad on the card face.
