for instructions on installing these cables.
Removing a SAN768B-2 from the cabinet
If you need to remove a SAN768B-2 chassis from a cabinet to move it to a new
location, follow the instructions below to remove the chassis, and then follow the
installation instructions (“Installing a SAN768B-2 in a cabinet” on page 14) to
install the chassis in the new cabinet. If you are replacing the chassis, follow the
complete instructions in “Removing and replacing the chassis” on page 101.
Attention: Refer to “Safety notices and labels” on page xiii before starting any
service procedure. Due to the weight of the product, this procedure requires a lift
tool. See “Ordering the lift tool” on page 12 for information on ordering the lift
tool.
Step 1 through step 5 describes how to use the lift tool (PN 09P2481) and the
24–inch load plate (PN 11P4369) to remove a SAN768B-2 from the cabinet. Step 6
through step 17 on page 30 describes how to remove the bridge tool (PN 18P5855)
from the cabinet.
Perform the following steps to remove a SAN768B-2:
1. Assemble the lift tool if it is not assembled. The assembly and disassembly
instructions are included with the lift tool.
2.
Remove both power cords from the SAN768B-2.
3. Optionally, remove the power supplies and blower assemblies to reduce the
weight.
4. Remove the chassis door from the chassis. See “Removing the chassis door
and cable management comb” on page 19.
5. Remove the three 10-32 x 5/8 in. Phillips panhead screws with washers on
each side. See Figure 9 on page 24 for the location of the screws.
6. If you are replacing the lower SAN768B-2, go to step 7. If you are replacing
the upper SAN768B-2, go to step 8 on page 30.

Install the bridge tool by completing the following steps:
a. Remove the bridge tool from its box and adjust the two supports 45°.
b.
Hold the bridge tool between the two vertical supports near EIA unit 3.
c. Move the two supports another 45°. Make sure that the following
conditions are met:
v
The two-pin section of the support is on the back of the vertical support.
v The one-pin section of the support is on the front of the vertical support.
d. Align the two-pin section of the support on the back of the vertical rail
with the bottom and middle holes in EIA unit 3.
e. Align the one-pin section of the support on the front of the vertical rail
with the middle hole in EIA unit 1.
Note:
Tilt the bridge tool towards the back of the cabinet approximately
45° to make it easier to align the two-pin and one-pin sections with
the vertical support.
f. Lock the shelf into position.
