Installing the Chassis
DETAILED STEPS
Step 1
To lighten the chassis, we recommend that you remove the fan trays from the chassis. The electronics on these modules
are well sealed from damage but you must still be careful not to damage their connectors. To remove a fan tray, follow
these steps:
a) Unscrew the four captive screws on the front of the fan tray until they are no longer in contact with the chassis.
b) Grab the fan tray handle and pull the fan tray part way out of the chassis.
c) Place your other hand under the chassis to support its weight and pull the fan tray fully out of the chassis.
d) Place the fan tray on an antistatic surface where nothing touches its connectors on the back of the module.
e) If there are power supplies in the chassis, remove the power supplies to minimize the weight of the chassis. The
chassis does not ship with power supplies installed, but if you are moving a previously installed chassis, be sure that
the power supplies are removed (for instructions on removing power supplies, see the
AC Power Supply Unit During Operations" section on page 10-4
Step 2
Load the chassis onto a mechanical lift 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 [0.6 cm] below the bottom
of the chassis).
c) Use at least 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. Push only the lower half of the frame of the chassis (never push on the modules installed in
the chassis and do not use their handles to guide the chassis).
Tip Use a third person to guide the chassis and to make sure that it does not collide with anything or tip over.
Warning To prevent personal injury or damage to the chassis, never attempt to lift or tilt the chassis using the handles
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
To lift the chassis, use a mechanical lift, not the handles on the side of the chassis (the handles are not rated
Caution
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 four-post 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 bracket.
Step 4 Use at least two persons to push the chassis half way onto the installed bottom-support rails as shown in

it does not get caught on anything as it is pushed into the rack.
Push evenly on both sides of the lower half of the front side of the chassis so that the back side enters the rack

first. and push until the chassis is half way onto the rack.
Tip Use the third person to be sure that the back end of the chassis does not get caught on the expansion edge of
the bottom support rails.
