Installing the Chassis on a Four-Post Rack or Cabinet
3 Place one hand under the power supply to support its weight and pull the power supply out of the chassis.
4 Place the power supply on an antistatic surface.
• To remove a fan tray, follow these steps:
1 Unscrew the four captive screws on the front of the fan tray (one captive screw in each corner of the front of
the fan tray).
2 Hold both handles on the fan tray with both of your hands and pull the fan tray out of the chassis.
3 Place the fan tray on an antistatic surface.
• To remove a fabric module, follow these steps:
Before you can remove a fabric module, you must remove the fan tray that is installed in front of
Note
it.
1 Press the lever eject button found in the middle of the front of the module.
2 Rotate both of the levers away from the fabric module.
3 When the other end of each lever is no longer holding onto the chassis, pull the two levers to slide the module
a couple inches out of the chassis.
4 Rotate the two levers back to the fabric module. Each lever will click when locked in place.
5 Place one hand on the front of the module and place your other hand under the module to support its weight.
6 Slide the module out of the chassis and place the module on an antistatic surface.
Step 2
Load the chassis onto a mechanical lift or floor jack as follows:
a) Position the mechanical lift next to the shipping pallet that holds the chassis.
b) Elevate the lift platform to the level of the bottom of the chassis (or no more than 1/4 inch [0.635 cm] below the
bottom of the chassis).
c) Use two persons to slide the chassis fully onto the lift so that the side of the chassis touches or is close to the vertical
rails on the lift. Make sure that the front and rear of the chassis are unobstructed so you can easily push the chassis
into the rack.
To prevent personal injury or damage to the chassis, never attempt to lift or tilt the chassis using the handles
Warning
on modules (such as power supplies, fans, or cards); these types of handles are not designed to support the
weight of the unit.
Statement 1032
Caution To lift the chassis, use a mechanical lift. Do not use the handles on the side of the chassis (the handles are
not rated for lifting over 200 pounds [91 kg]). Use the side handles for only repositioning the chassis after it
is already on the mechanical lift or in the rack or cabinet.
Step 3
Use the mechanical lift to move and align the rear of the chassis to the front of the rack or cabinet.
Make sure that the bottom of the chassis is elevated to the height of the bottom-support rails or no more than 1/4 inch
(0.6 cm) above the rails.
Step 4 Push the chassis halfway onto the rack or cabinet.
