 Hardware Installation 2-3

Installing an LS2020 Switch in Rack

Step 3

Remove the following chassis components to reduce the weight of the system during
installation.

Blowers (top front and top rear)

Power supplies (right rear)

These components are located behind removable covers. Figure 2-1 shows the front view
of the LS2020 chassis, while Figure 2-2 shows the rear view of the chassis.

If your system is fully configured with function cards, you may also remove some or all of
these cards to further reduce the weight of the chassis. (Refer to the LightStream 2020
Hardware Reference and Troubleshooting Guide 
for component removal instructions.) Put
all removed electronic components in antistatic shielding bags or place them on antistatic
mats.

Note

Do not remove disk assemblies as a means of reducing chassis weight.

Step 4

Determine the desired mounting position in the rack for the LS2020 switch. Attach the clip
nuts from the country kit or the rack mounting kit to the appropriate positions on the rack
rails.

See Figure 2-1 for the location of mounting screw slots. (If your rack has metric-threaded
or non-standard rails, you may need to provide your own mounting hardware.)

Step 5

Lift the LS2020 chassis into the desired mounting position in the rack.

Warning

An LS2020 chassis is heavy, particularly if it is completely configured with function

cards. (The weight of the system ranges from 94 to 147 pounds, depending on the system
configuration.) Do not risk personal injury or equipment damage by attempting to transport or lift
the system without assistance.

Caution

Do not use the disk assembly handles to lift the chassis. These handles, shown in

Figure 2-1, are not designed for weight-bearing loads and may break off if used to lift the chassis.

Step 6

Using the mounting screws and washers included in your country kit or rack mounting kit,
secure the flanges on the front of the LS2020 chassis to the rack.

Step 7

Replace any items that you removed from the chassis in Step 3 above (blowers, power
supplies, function cards, and covers) before installing the chassis into the rack.
