•
The AC power receptacles used to plug in the chassis must be the grounding type. The grounding
conductors that connect to the receptacles should connect to protective earth ground at the service
equipment level.
Cabling Requirements
When running power and data cables together in overhead cable trays or subfloor cable trays, be aware of the
following caution:
We strongly recommend that power cabling runs and other potential noise sources be located as far away
as practical from LAN cabling that terminates on Cisco equipment. In situations where this type of long
parallel cable runs exist and cannot be separated by at least 3.3 feet (1 meter), we recommend that you
shield these potential noise sources. To avoid interference, the source should be shielded by housing it in
a grounded metallic conduit.
Caution
Also be aware of the following caution concerning the use of Category 5e and Category 6 Ethernet cables:
Category 5e, Category 6, and Category 6a cables can store large levels of static electricity because of the
dielectric properties of the materials used in their construction. Always ground the cables (especially in
new cable runs) to a suitable and safe earth ground before connecting them to the module.
Caution
Rack-Mounting Guidelines
The Cisco Catalyst 6807-XL Switch is designed to be installed in both open and enclosed racks. The switch
can be installed on 19-inch equipment racks. If you are using a 2-post or 4-post 19-inch standard equipment
rack, before rack-mounting the switch, ensure that the equipment rack complies with these guidelines:
•
The width of the rack, measured between the two front-mounting rails, must be one of the following
measurements:
•
17.5 inches (44.45 cm)
•
17.75 inches (45.09 cm)
•
The depth of the rack, measured between the front-mounting and rear-mounting strips, must be at least
17.61 inches (44.72 cms).
•
The rack must have sufficient clearance in terms of height and depth, to insert the chassis. The chassis
height is 17.5 inches (44.45 cms).
Chassis height is sometimes measured in rack units (RU or just U) where 1 RU or 1 U
equals 1.75 inches (44.45 mm). A typical server rack is 42 RU or 42 U in height. The
Cisco Catalyst 6807-XL Switch chassis is 10 RU in height.
