2. Install the rackmount brackets on the inner slide rail by performing the following
steps.
These rackmount brackets prevent the switches from sliding all the way out of the
rack in the event the rack is accidentally moved.
Note – To meet air flow requirements, the 3200, 3250, and 3850 switches are
mounted with their port sides facing the back of the cabinet (rack).
a. Position a rackmount bracket at the end of one of the inner slide rails (the end
that does not contain the lock release lever), as shown in
FIGURE 1-1
.
b. Attach the rackmount bracket to the slide rail using two of the slotted head
8-32 x 3/8-inch screws, with a lock nut on the end of each screw.
c. Tighten the screws to a torque of 15 inch-pounds (17.3 cm-kgs).
d. Repeat Steps a through c with the second inner slide rail.
3. Attach two of the three-hole slide mount L-brackets to each outer slide rail.
a. See
FIGURE 1-2
. Use two of the slotted head 8-32 x 3/8-inch screws per L-bracket,
with the screw heads on the inside of the slide rails and a lock nut on the end
of each screw.
b. Tighten the screws to a torque of 15 inch-pounds (17.3 cm-kgs).
4. Install the inner slide rails to the 3200, 3250, or 3850 switch chassis by performing
the following steps.
a. Position one of the inner slide rails with the flat side against the switch.
To allow the fan side of the switch to slide out the front of the rack, orient the rail
as shown in
FIGURE 1-1
, with the end containing the lock release lever towards the
port side of the switch.
b. Attach the rail to the 3200, 3250, or 3850 switch by using two of the Phillips 8-32
x 3/16-inch screws. See
FIGURE 1-1
.
Caution – Using screws longer than 3/16-inch on the 3200, 3250, and 3850 switch
chassis can damage the switch.
c. Tighten the screws to a torque of 15 inch-pounds (17.3 cm-kgs).
d. Repeat Steps a and b with the second inner slide rail on the other side of the
3200, 3250, or 3850 switch.
