3 Remove the chassis from the rack, and package it for shipment.
24 Mount the replacement chassis.
While supporting the chassis, slide the chassis into the cabinet mounting position. Secure the
chassis to the cabinet mounting rails using the four mounting screws provided with the unit.
Tighten the screws to 4.5 Nm (40 in-lb).
35 Reconnect the cabling to the replacement chassis as defined in Step 2.
Use the SMA torque wrench for all SMA connectors.
6 Using the breakers on the PDU, turn up the BIC, AIC, and RBS 1 (and RBS 2 and RBS 3 if
present), and then verify that the components are operational before proceeding.
