Installation and safety considerations
2
• The equipment in the rack is grounded through a reliable branch circuit connection and
maintains ground at all times. Do not rely on a secondary connection to a branch circuit, such
as a power strip.
• Airflow and temperature requirements are met on an ongoing basis, particularly if the switch is
installed in a closed or multirack assembly.
• The additional weight of the switch does not exceed the rack’s weight limits or unbalance the
rack in any way.
• The rack is secured to ensure stability in case of unexpected movement, such as an
earthquake.
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 rack or patch panels to reduce potential tangling of the cables. The following list
proveides some recommendations for cable management:
NOTE
You should not use tie wraps with optical cables because they are easily overtightened and can
damage the optic fibers.
• 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 Brocade 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 Velcro-style straps to secure and organize fiber-optic cables.
Items required for installation
The following items are required for installing, configuring, and connecting the Brocade 6520 for
use in a network and fabric:
• 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
• Ethernet cable
• Brocade-branded SFP+s transceivers and compatible cables (Brocade-branded 16 Gbps
SFP+s transceivers required for 16 Gbps performance), as required
• Access to an FTP server or USB device for backing up the switch configuration (optional)
