Installing the SAN Switch Cabling and Configuring the SAN Switch 2/8V, 2/16V or 2/16N The SAN Switch 2/8V or 2/16V 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 Fabric OS Procedures 4.2x User Guide. For more information about the commands used in this procedure, refer to the HP StorageWorks Fabric OS 4.2.x Command Reference Guide. Recommendations for Cable Management The minimum bend radius for a 50 micron cable is 2 inches under full tensile load and 1.2 inches with no tensile load. Cables can be organized and managed in a variety of ways: for example, using cable channels on the sides of the cabinet or patch panels to minimize cable management. Following is a list of recommendations: ■ Plan for rack space required for cable management before installing the switch. ■ 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 Fabric OS Features 4.2.x User Guide. ■ 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. SAN Switch 2/8V, 2/16V and 2/16N Installation Guide 47

Recommendations for Cable Management
The minimum bend radius for a 50 micron cable is 2 inches under full tensile load
and 1.2 inches with no tensile load.
Cables can be organized and managed in a variety of ways: for example, using
cable channels on the sides of the cabinet or patch panels to minimize cable
management. Following is a list of recommendations:
■
Plan for rack space required for cable management before installing the
switch.
■
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 Fabric OS Features 4.2.x User Guide
.
■
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.
