For the ease of assembly, install the plenum assemblies to the top of
the equipment and tighten the bolts just enough to hold everything in place
safely. Do not torque the bolts until all the hardware and plenum assemblies
are in place.
Follow the steps below to install the plenum and its accessories.
1. Remove the hardware from the front and rear flange of the main
bus enclosure as shown in
and keep it aside for later
reassembly.
Figure 23. Removing the hardware from the front and rear flange.
2. Lift the plenum assembly using the plenum lifting plates and
place it on top of the gear.
3. Ensure that the correct plenum is being installed on top of the
structure by matching the label on the main bus enclosure with
the label on the plenum.
