• Secure the rack to ensure stability in case of unexpected movement, such as an earthquake. Cabling considerations Before installing the switch, plan for cable management based on the following HP recommendations: • Leave enough space to allow for the fact that 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 1 m (3.28 ft) 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 administrator 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. • Use velcro straps to secure and organize fiber optic cables. Do not use tie wraps on fiber optic cables, because wraps are easily overtightened and can damage the optical fibers. NOTE: 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. Items required for installation Obtain the following: • 8Gb SAN Switch installed and connected to a power source • Workstation with an installed terminal emulator, such as HyperTerminal • Unused IP address and corresponding subnet mask and gateway address • Serial cable (supplied with switch) • Ethernet cable • SFP transceivers and compatible cables, as required • Access to an FTP server to back up the switch configuration (optional) 28 Installing and configuring an 8Gb SAN Switch

Cabling considerations
Before installing the switch, plan for cable management based on the following HP recommendations:
•
Leave enough space to allow for the fact that 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 1 m (3.28 ft) 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 speci
fi
c requirements, as described in the
HP StorageWorks Fabric OS
administrator guide
.
•
For easier maintenance, label the
fi
ber 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.
•
Use velcro straps to secure and organize
fi
ber optic cables. Do not use tie wraps on
fi
ber optic
cables, because wraps are easily overtightened and can damage the optical
fi
bers.
NOTE:
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.
