Replacing the cable guides (pillars)

You can use cable guides (pillars) to organize the port cables into logical groups, such as port
quads (sets of four neighboring ports). The cable pillars do not attach to the chassis.
The cable pillars also serve to keep the cables evenly spaced and hold them away from the
16-port card to prevent them from bending to less than the minimum bend radius.
CAUTION:
of the port side of the chassis. Arrange the cables so that the minimum bend radius is not
exceeded; for a 50-micron cable, the minimum bend radius is 2 inches under full tensile load
and 1.2 inches with no tensile load. Tie wraps are not recommended for optical cables
because they are easily overtightened and can break the optical cables.
To replace the cable pillars, orient them horizontally and insert the cables into the holes, using
a separate hole for each cable (see

Preliminary steps

Take the following steps before removing and replacing a 16-port card:
1. Check the LEDs.
The LEDs are located on the front panel of each 16-port card (see
"16-port
NOTE: The WWN bezel on the nonport side of the switch also displays a power and status
LED for each 16-port card.
2. Establish a telnet or console session.
Before replacing a 16-port card, establish a telnet or console connection to identify a
failure and verify operation after replacement. For information about how to check the
status of hardware components using the CLI, refer to the HP StorageWorks procedures
user guide for the Fabric OS version running on your switch.
