The 8520 Series switch can be attached to a standard 19-inch equipment rack, in either of
the following ways:
Four-post rack, using the mounting
kit provided.
Two-post rack, using mounting
brackets (not provided) to attach the front or the middle of the switch to the
posts.
To attach a switch to a two-post rack, a four-post rack, or a cabinet, follow these
steps.
Note
Take care to load the rack so that it
is not top-heavy. Start installing equipment at the bottom and work up.
Four-Post Rack Mount
A four-post rack-mounting kit is included in the box with your switch. The kit
contains an instruction sheet, along with the following components:
Two mounting brackets, known
as inner member in the instruction sheet. These pieces attach
directly to both sides of the switch housing.
Two slider assemblies, one
for each side of the switch. Each slider assembly consists of an outer piece
that is secured to the rack and a sliding rail to which you will attach the
corresponding mounting bracket. These pieces are known on the instruction
sheet as the outer member and intermediate
member.
Mounting ears - Black rack
ears with a thumb screw in the middle (2 count)
Black mounting ear screws (4
count)
To attach your switch to a four-post rack, follow these steps:
On one side of the switch, locate and remove the 2 black screws next to the data
ports on the switch. Repeat as needed for the opposite side.
Using the provided mounting ear screws, attach each of the mounting ears using
the holes exposed in the previous step. Ensure that the mounting ears are flush
with the faceplate of the switch.
Extend the slider assembly to the fullest extent. Locate the small white release
tab on the mounting bracket and push it toward the blue release tab, allowing
the mounting bracket to slide the rest of the way off the slider assembly.
Repeat this step for the other slider assembly.
Attach a mounting bracket to each
side of the switch housing, using the screws provided. Ensure that the blue tab
is close to the mounting ear and away from the switch.
Attaching a Mounting
Bracket to One Side of the Switch Housing
Attach the slider assemblies to
the front and rear rack posts, clicking into place at each end.
Attaching the Slider
Assembly to the Front Rack Post
Attaching the Slider
Assembly to the Rear Rack Post
Locate the intermediate rail
inside each slider assembly and pull it out to its fullest extent. (It remains
attached to the slider assembly.)
Extending the Slider
Assembly to Fit the Rack
Push the switch in until both
mounting brackets engage with the sliding rails.
Engaging the Mounting
Brackets with the Rail Assemblies
Release the tabs on both slider
assemblies, and carefully push the switch back until it is firmly in place.
Pushing the Mounting
Brackets into the Rail Assemblies
Screw the mounting ear
thumbscrews into the rack rails to hand tightness.
Completed
Installation: Switch in 4-Post Rack
Two-Post Rack Mount
You can attach the switch to a two-post rack in either of two configurations:
Front mount
Mid-mount
The side of the switch has different sets of holes for attaching mounting brackets in
either configuration.
Brackets for a two-post mount are not included in the box with the switch. However,
they can be ordered separately using part number XN-2P-RKMT299.
To attach the switch to a two-post rack, follow these steps:
On one side of the switch, attach
one of the short mounting brackets to the switch housing.
For a front mount,
position the bracket over the holes so that the flange (ear) is even
with the front of the switch, as shown in the figure below:
Attaching a
Short Mounting Bracket (Ear): Front of Switch
For a mid-mount, position
the bracket so that the flange (ear) is positioned slightly more than
halfway between the front and back of the switch, as shown in figure
below:
Attaching a
Short Mounting Bracket (Ear): Middle of Switch
Use four small mounting
screws (provided) to attach the bracket to the switch.
Attach the other short mounting
bracket to the other side of the switch housing, as you did in step 2.
Secure the brackets to the rack
posts using rack-mounting screws that are appropriate for the rack (not
provided).
If the switch comes with installed AC power supplies, skip to the topic: Turn on the Switch.
If the switch does not have an installed power supply, install one or two power
supplies using the instructions in Install Internal Power Supplies.
