Eia Rack Considerations; Recommendations For Cable Management; Items Required For The Installation - Brocade Communications Systems VDX 6940 Series Hardware Installation Manual

EIA rack considerations

For successful installation and operation of the device in a rack, ensure the following rack requirements are met:
∙
The rack must be a standard EIA rack.
∙
For 1U devices, the rack space required is one rack unit (1U) 44.45 mm (1.75 in.) high and 440 mm (17.5 in.) wide.
∙
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.
∙
Ensure that the rack mounting does not impede airflow or negatively affect temperature requirements, particularly if the device
is installed in a closed or multirack assembly. Ensure that airflow openings on the port and nonport side of the device are not
obstructed.
CAUTION
Make sure the airflow around the front, sides, and back of the device is not restricted.
∙
The additional weight of the device 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.
DANGER
Make sure the rack housing the device is adequately secured to prevent it from becoming unstable or falling over.

Recommendations for cable management

The minimum radius to which a 50-micron cable can be bent under full tensile load is 5.1 cm (2 in.). For a cable under no tensile load,
that minimum is 3.0 cm (1.2 in.).
Cables can be organized and managed in a variety of ways; for example, use cable channels on the sides of the EIA rack or patch panels
to reduce the potential for tangling the cables. The following list provides 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. Velcro-
like wraps are recommended.
∙
Plan for the rack space required for cable management before installing the device.
∙
Leave at least 1 m (3.28 ft) of slack for each port cable. This provides room to remove and replace the device, allows for
inadvertent movement of the rack, and helps prevent the cables from being bent to less than the minimum bend radius.
∙
For easier maintenance, label the cables and record the devices to which they are connected.
∙
Keep LEDs visible by routing port cables and other cables away from the LEDs.

Items required for the installation

The following items are required for installing, configuring, and connecting the device for use in a network and fabric:
∙
A workstation with an installed terminal emulator, such as HyperTerminal.
∙
An unused IP address and corresponding subnet mask and gateway address.
∙
A serial cable (provided).
∙
An Ethernet cable.
∙
Power cord (provided).
