Meeting Space Requirements for the Rack
The rack must have enough space around it for servicing. To ensure adequate space, do the following:
1 Provide enough space in front of and behind the switch so that you can service it easily.
2 Allow a minimum of 48 inches (122 cm) in front of the rack and 24 inches (61 cm) behind the rack.
3 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.
Securing the Rack
1 Attach the rack to the 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 14: Properly Secured Rack
on page 38.
