10. If you removed any fan modules before moving the chassis, reinstall each one in the chassis as
follows:
a) Holding each of the two handles on the fan module with your two hands, align the fan module to
an open fan module slot.
Note : The two alignment brackets on top of the fan module should align to two tracks at the top
of the slot.
b) Slide the fan module into the slot until the front of the fan module comes in contact with the rear
of the chassis.
Note : The two alignment pins on the fan module (on the top and one on the bottom) should go
into holes in the chassis and the four captive screws on the fan module should align to screw holes
in the chassis.
c) Screw in the four captive screws to the chassis and tighten each screw to 8 in-lb (0.9 N-m).
11. If you removed any power supplies before moving the chassis, reinstall each one as follows:
a) Determine which power supply slots to fill and ensure that each of those slots is open.
b) If you are using the combined or power supply redundancy mode, you can use any slot for the
power supply that you are installing.
c) If you are using the input-source or full redundancy mode, you must group the power supplies that
are to be connected to the same grid on either the left or right power supply slots in the chassis
(that is, place the power supplies for grid A in slots 1 or 2 or both slots and place the power
supplies for grid B in slots 3 or 4 or both slots). For information on the power supplies supported
by SAN c-type family switches, see "Power Supplies" on page 39.
d) Place one hand on the front of the power supply and place your other hand under it to support its
weight.
e) Align the power supply to an open power supply slot.
Note : The alignment bracket on top of the power supply should align to a track at the top of the
slot and a bar at the bottom of the power supply should be guided by a track at the bottom of the
slot.
12. Slide the power supply all the way into the slot until its release handle clicks and the module stops.
Installing the SAN384C-6 or SAN768C-6 Device on a Four-Post
Rack or Cabinet
This section is applicable to the SAN384C-6 and SAN768C-6 switches.
Before you begin
Before installing the device into a rack or cabinet, verify the following:
• Verify that the chassis shipment is complete and undamaged.
• Verify that a rack or cabinet is installed and secured to the subfloor.
Warning : Stability hazard. The rack stabilizing mechanism must be in place, or the rack must be
bolted to the floor before you slide the unit out for servicing. Failure to stabilize the rack can cause
the rack to tip over.
• Verify that the bottom-support rails have been attached to the lowest possible RU in the rack or cabinet
and there is 14 RU (24.5 inches [62.2 cm]) of space above the rails to install the chassis.
• For SAN768C-6 chassis, verify that the bottom-support rails have been attached to the lowest possible
RU in the rack or cabinet and there is 25 RU (43.75 inches [111 cm]) of space above the rails to install
the chassis.
• If there are other devices in the rack, verify that the devices that are heavier than this chassis are
installed below where you are going to install the chassis and lighter devices are installed above where
you are going to install the chassis.
