v The cabinet is 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 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:
v Plan for rack space required for cable management before installing the switch.
v
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.
v 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.
v
For easier maintenance, label the fiber optic cables and record the devices to
which they are connected.
v Keep LEDs visible by routing port cables and other cables away from the LEDs.
v 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.
Items required for installation
The following items are required for installing, configuring and connecting the
SAN48B-5 for use in a network and fabric:
v
Workstation with an installed terminal emulator, such as HyperTerminal.
v Unused IP address and corresponding subnet mask and gateway address
v
Serial cable (provided) if not using EZSwitch Setup
v Ethernet cable
v Brocade-branded SFP+s and compatible cables (Brocade-branded 16 Gbps SFP+s
are required for 16 Gbps performance), as required
v
Access to an FTP server or the USB device for backing up the switch
configuration (optional)
Setting up the switch as a standalone unit
Attention: Refer to “Safety notices and labels” on page xiii before starting any
installation procedure.
To install the switch as a standalone unit, use the following procedure:
1.
Unpack the switch and verify that all items listed in “Items included with the
switch” on page 5 are present and undamaged.
2. Clean the four corner depressions on the bottom of the switch enclosure, place
an adhesive rubber foot in each one, and firmly press into place. The rubber
feet on the switch help prevent the switch from sliding off the supporting
surface.
3. Place the switch on a flat, sturdy surface.
