The top of the module has an alignment bracket running from the rear to the front. The electrical
connectors will be at the bottom.
Note
b) Align the rear of the fabric module to an open fabric slot and insert the bracket on top of the module in
the track at the top of the slot.
If there are only three fabric modules to install, install them in fabric slots 1, 3, and
5.
Note
c) Slide the module part way into the slot.
d) Unscrew the captive screw on each of two ejector levers on the front of the module and rotate the two
levers away from the module.
e) Holding the levers, slide the module all the way into the slot until it stops.
f) Simultaneously rotate both levers to the front of the module and secure them to the module by screwing
their captive screws to the module. Tighten each screw to 8 in-lb (0.9 N·m).
Step 10
If you removed any fan trays before moving the chassis, reinstall each one in the chassis as follows:
a) Holding each of the two handles on the fan tray with your two hands, align the fan tray to an open fan tray
slot.
The two alignment brackets on top of the fan tray should align to two tracks at the top of the
slot.
Note
b) Slide the fan tray into the slot until the front of the fan tray comes in contact with the rear of the chassis.
The two alignment pins on the fan tray (on the top and one on the bottom) should go into holes
in the chassis and the four captive screws on the fan tray should align to screw holes in the chassis.
Note
c) Screw in the four captive screws to the chassis and tighten each screw to 8 in-lb (0.9 N·m).
Step 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.
If you are using the combined or power supply redundancy mode, you can use any slot for the power
supply that you are installing. If you are using 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, 2, 5, or 6 and place the power supplies
for grid B in slots 3, 4, 7, or 8).
b) Place one hand on the front of the power supply and place your other hand under it to support its weight.
c) Align the power supply to an open power supply slot.
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.
Note
d) Slide the power supply all the way into the slot until it stops.
e) Slide the handle in the middle of the ejector lever toward the end of the lever and rotate the lever to the
front of the power supply. Release the middle handle.
The lever should grab the inside of the slot and push the power supply onto its mid plane
connectors.
Note
f) Screw in the two captive screws on the front of the power supply to the chassis. Tighten each screw to 8
in-lb (0.9 N·m).
Step 12
Connect each installed power supply with an AC power circuit as follows:
If you are using combined power mode (no power redundancy) or power supply (
n
+1) power mode,
connect all of the power supplies to the same power circuit (grid). If you are using input source (
n
+
n
)
or full power mode, connect half of the power supplies (located in slots 1, 2, 5, 6, 9, 10, 13, and 14)
to one AC power circuit and the other half of the power supplies (located in slots 3, 4, 7, 8, 11, 12,
15, and 16) to another AC power circuit. When you connect each power supply to an AC power
circuit, the LEDs on the power supply turn on. The switch can operate when each of the required
power supplies have a green OUTPUT LED lit.
