Attaching Bottom-Support Rails to a Two-Post Rack for the SAN192C-6
Director
Use this procedure to attach the bottom support rails to a two-post rack for the
SAN192C-6 Director.
Before you begin
Before you can install the bottom support rails for the chassis, you must do the
following:
v
Verify that a two-post rack is installed and secured to the concrete subfloor (see
Installing a Rack or Cabinet).
v
If any other devices are stored in the rack or cabinet, verify that they are located
below where you plan to install the switch. Also, verify that lighter devices in
the same rack are located above where you plan to install this switch.
v
Verify that the two-post bottom-support rails kit was ordered and shipped with
the chassis.
About this task
The bottom-support rails support the weight of the switch chassis in the rack or
cabinet. To maximize the stability of the rack, you must attach these rails at the
lowest possible rack unit (RU).
Note:
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:
v
This unit should be mounted at the bottom of the rack if it is the only unit in
the rack.
v
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.
v
If the rack is provided with stabilizing devices, install the stabilizers before
mounting or servicing the unit in the rack.
Procedure
1.
Position one of the two bottom-support rails at the lowest possible RU in the
rack or cabinet. Be sure there is at least 9 RU of vertical space above the rails to
install the chassis.
2.
Use a manual Phillips torque screwdriver to attach the bottom-support rail to
the rack using four M6 x 19 mm or 12-24 x 3/4 inch screws and tighten each
