BlackDiamond 12800 Series Switches Hardware Installation Guide
47
NOTE
Because building codes vary worldwide, Extreme Networks strongly recommends that you consult an electrical
contractor to ensure proper equipment grounding for your specific installation.
Space Requirements for the Rack
Provide enough space in front of and behind the switch so that you can service it easily. Allow a
minimum of 48 inches (122 cm) in front of the rack and 24 inches (61 cm) behind the rack. When using a
relay (two-post) rack, provide a minimum of 24 inches (61 cm) of space behind the mounted equipment.
Extra room on each side is optional.
WARNING!
A BlackDiamond chassis does not have a switch for turning power to the unit on and off. For systems using an AC
power supply, power to the chassis is disconnected by removing the wall plug from the electrical outlet. For systems
using a DC SSI power supply, power to the chassis can be turned off by lifting the handle on the power supply or by
de-energizing the circuit that feeds the power supply, which is usually accomplished by turning off a circuit breaker.
Securing the Rack
The rack should be attached to the wiring closet floor with 3/8-inch (9.5 mm) lag screws or equivalent
hardware. The floor under the rack should be level within 3/16-inch (5 mm). Use a floor-leveling
cement compound if necessary or bolt the racks to the floor as shown in Figure 22.
Figure 22: Properly Secured Rack
Brace open equipment racks if the channel thickness is less than 1/4 inch (6.4 mm).
