Cabling and configuring the SAN Switch

The SAN Switch must be configured to ensure correct operation within a network and fabric.

For instructions about configuring the switch to operate in a fabric containing switches from

other vendors, refer to the

HP StorageWorks procedures user guide

for the Fabric OS version

running on your switch. For more information about the commands used in this procedure, refer

to the

HP StorageWorks command reference guide

for the Fabric OS version running on your

switch.

NOTE: All supporting Fabric OS documentation resides on the Software CD that shipped with

your switch.

Recommendations for cable management

Following is a list of HP recommendations for cable management:

• Plan for rack space required for cable management before installing the switch.

• The minimum bend radius for a 50 micron cable is 2 inches under full tensile load and 1.2

inches with no tensile load.

• Leave at least 3.28 ft. (1 m.) of slack for each port cable. This provides room to remove and

replace the switch, allows for inadvertent movement of the rack, and helps prevent the

cables from being bent to less than the minimum bend radius.

• If you are using ISL Trunking, consider grouping cables by trunking groups. The cables used

in trunking groups must meet specific requirements, as described in the

HP StorageWorks

features overview

, located on the Software CD that shipped with your switch.

• For easier maintenance, label the fiber optic cables and record the devices to which they

are connected.

• Keep LEDs visible by routing port cables and other cables away from the LEDs.

• Do not use tie wraps on fiber optic cables, because the wraps are easily overtightened and

can damage the optic fibers. HP recommends using Filcrow wraps.
