Cabling considerations, Items required for installation

Page 34 highlights

• Ground all equipment in the cabinet through a reliable branch circuit connection, and maintain ground at all times. Do not rely on a secondary connection to a branch circuit, such as a power strip. • Ensure that airflow and temperature requirements are met on an ongoing basis, particularly if the switch is installed in a closed or multirack assembly. • Verify that the additional weight of the switch does not exceed the cabinet's weight limits. • 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 meter (3.28 feet) 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: • 8-Gb 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 NOTE: For FCoE Converged Network Switches, both HP-branded FC SFPs and CEE 10-GbE SFPs are required. FC SFP+ transceivers are required for 8-Gb/s performance; copper cables must be HP-branded. • Access to an FTP server to back up the switch configuration (optional) 34 Installing and configuring an 8-Gb SAN Switch

Ground all equipment in the cabinet through a reliable branch circuit connection, and maintain
ground at all times. Do not rely on a secondary connection to a branch circuit, such as a power
strip.
Ensure that airflow and temperature requirements are met on an ongoing basis, particularly if the
switch is installed in a closed or multirack assembly.
Verify that the additional weight of the switch does not exceed the cabinet
s weight limits.
Secure the rack to ensure stability in case of unexpected movement, such as an earthquake.

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

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

For easier maintenance, label the fiber optic cables, and record the devices to which they are
connected.
