Site preparation and installation requirements

The following conditions are required to ensure correct installation and operation of the switch.

Attention: Follow ESD precautions whenever handling the switch or components. See ESD precautions.

Electrical requirements

For successful installation and operation of the switch, ensure that the following electrical requirements are met:

  • The primary outlet is correctly wired, protected by a circuit breaker, and grounded in accordance with local electrical codes.
  • It is best practice that each power supply obtain its power from a different protected and wired source.
  • The supply circuit, line fusing, and wire size are adequate, as specified by the electrical rating on the switch nameplate.
  • The power supply standards are met. See Power supply specifications.
    Attention: To maximize fault tolerance, connect each power cord to a separate power source.

Environmental considerations

For successful installation and operation of the switch, ensure that the following environmental requirements are met:

  • At a minimum, adequate cooling requires that you install the switch with the intake side (non port side), facing the cool-air aisle.
  • All equipment in the rack should force air in the same direction to avoid intake of exhaust air.
  • Airflow requirements outlined in Environmental requirements must be met.
  • The ambient air temperature does not exceed 40° C (104° F) while the switch is operating.

Cabinet requirements

For successful installation and operation of the switch in a cabinet, ensure that the following cabinet requirements are met:

  • The cabinet must be a standard EIA cabinet.
  • Plan for a rack space that is two rack units (2U) high; 8.90 cm (3.50 in.) high and 48.3 cm (19 in.) wide, and at least 61 cm (24 in.) deep.
  • Ground all equipment in the rack 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.
  • Verify that the additional weight of the switch does not exceed the rack’s weight limits or unbalance the rack in any way.
  • The cabinet must be secured to ensure stability in case of unexpected movement, such as an earthquake.

Planning for cable management

Attention: The minimum bend radius for a 50 micron cable is 5.1 cm (2 in.) under full tensile load and 3.0 cm (1.2 in.) 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. Use this list of recommendations to guide your planning.
  • Plan for rack space required for cable management before installing the switch.
  • 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 Fabric OS Administrator’s 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 hook and loop style straps to secure and organize fiber optic cables. Do not use tie wraps with optical cables; they can be easily overtightened and can damage the optic fibers.
  • Record port and cable connections using a table such as Cable routing table.

Items required for installation

The following items are required for installing, configuring, and connecting the SAN 42B-R for use in a network and fabric.
  • Clamps or other means of temporarily supporting the switch in the rack
  • #2 Phillips torque screwdriver
  • 1/4-inch slotted-blade torque screwdriver
  • Workstation with an installed terminal emulator, such as HyperTerminal.
  • Unused IP address and corresponding subnet mask and gateway address
  • Items from the accessory kit that accompanies the switch
  • Serial cable (provided) if not using EZSwitch Setup
  • Ethernet cable
  • SFP+ transceivers and compatible cables, as required
  • Access to an FTP server or the USB device for backing up the switch configuration (optional)
