The rack post holes can be square 0.38-inch (9.6 mm), round 0.28-inch (7.1 mm), #12-24 UNC, or
#10-32 UNC when you use the supplied slide rails.
• The minimum vertical rack space per appliance must be two RUs, equal to 3.5 in. (88.9 mm).
Equipment Requirements
The slide rails supplied by Cisco Systems for this appliance do not require tools for installation if you
install them in a rack that has square 0.38-inch (9.6 mm), round 0.28-inch (7.1 mm), or #12-24 UNC
threaded holes. The inner rails are pre-attached to the sides of the appliance.
However, if you install the slide rails in a rack that has #10-32 round holes, a bladed screwdriver is
required to remove the larger square/round mounting pegs from the
front of the slide rails.
Slide Rail Adjustment Range
The slide rails for this appliance have an adjustment range of 26 to 36 inches (660 to 914 mm).
Installing the Appliance in a Rack
This section describes how to install the appliance in a rack.
Warning
To prevent bodily injury when mounting or servicing this unit in a rack, you must take special
precautions to ensure that the system remains stable. The following guidelines are provided to ensure
your safety:
This unit should be mounted at the bottom of the rack if it is the only unit in the rack.
When mounting this unit in a partially filled rack, load the rack from the bottom to the top with the heaviest component
at the bottom of the rack.
If the rack is provided with stabilizing devices, install the stabilizers before mounting or servicing the unit in the rack.
Statement 1006
To install the slide rails and the appliance into a rack, follow these steps:
Step 1
Install the slide rails into the rack (see Figure 2-1 ):
a. Align the slide-rail assembly inside the rack posts with the length-adjustment bracket ( Figure 2-1 ,
item 4) toward the rear of the rack.
b.
Compress the length-adjustment bracket until the mounting pegs (item 5) and locking clips (item 6)
engage the desired rack holes on the front and rear rack posts.
– The mounting pegs fit square 0.38-inch (9.6 mm), round 0.28-inch (7.1 mm), or #12-24 UNC
threaded holes. They fit the shape of the hole when the pegs are compressed.
–
The smaller #10-32 round mounting pegs are enclosed in the center of the compressible rear
pegs. However, to use the #10-32 pegs, you must use a bladed screwdriver to remove the
square/round
front pegs.
