Installing Adjustable Mounting Brackets in a Rack or Cabinet for a J-EX8200 Switch
To mount the switch on a four-post rack or cabinet, you must first install the adjustable
mounting brackets in the rack or cabinet. (The remainder of this topic uses “rack” to mean
“rack or cabinet.”) The J-EX8200 switch comes with a four-piece set of adjustable
mounting brackets that supports the chassis in the rack.
NOTE: The adjustable mounting brackets are not for installation in two-post
racks.
The four adjustable mounting bracket pieces are:
•
1 left front adjustable mounting bracket. The bracket is labeled “LEFT FRONT” on the
side of the bracket that faces the interior of the rack, near the holes for attaching the
bracket to the rack.
• 1 right front adjustable mounting bracket. The bracket is labeled “RIGHT FRONT” on
the side of the bracket that faces the interior of the rack, near the holes for attaching
the bracket to the rack.
• 2 rear adjustable mounting brackets. These brackets are labeled “REAR” on the side
of the bracket that faces the interior of the rack, near the holes for attaching the bracket
to the rack. The rear brackets are interchangeable; you can use either of the rear brackets
with the right or left front adjustable mounting bracket.
Ensure that you have the following parts and tools available to install the adjustable
mounting brackets:
• A Phillips (+) screwdriver, number 1, 2, or 3, depending on the size of your rack mounting
screws
•
A Phillips (+) screwdriver, number 2 to install the screws that connect the rear and
front mounting brackets
• A flat-blade (-) screwdriver if you are installing the switch in a rack with square,
nonthreaded holes
•
16 screws—and 16 cage nuts and washers if your rack requires them—of the appropriate
size to attach the four mounting bracket pieces to the rack
When you install the adjustable mounting brackets, the “arms” of the brackets overlap.
The overlap area adjusts the total bracket length to fit three standard rack sizes: 23.62
in. (600 mm), 30 in. (762 mm), and 31.5 in. (800 mm).
To install the mounting brackets in a four-post rack (see Figure 37 on page 98):
1.
Remove the adjustable mounting brackets from the accessory box.
2.
Decide where to position the switch in the rack. If the rack is empty, position the switch
in the lowest possible location. See “Rack Requirements for a J-EX8208 Switch” on
