Installing Cross Connect Drawers

Chapter 2 Quick Installation Procedures

Installing Cisco ONS 15540 ESPx Hardware

The process for installing the cable storage and cross connect drawers is the same. The order of placement beneath the chassis is important, and the drawers should be installed in the following order from top to bottom:

a. Cable storage drawer

b. Cross connect drawer

c. Cross connect drawer

d. Cable storage drawer

e. Cross connect drawer

f. Cross connect drawer

The first cable storage drawer can be used for direct connections and for connections that use the first and second cross connect drawers. Each cable storage drawer stores cables for two cross connect drawers.

The cross connect and cable storage drawers ship with the rack mount ears already installed. To install the cross connect and cable storage drawers into the rack, follow these steps:

Step 1 Hold the drawer with both hands and position the drawer in the rack beneath the chassis. All drawers following this first one can be stacked directly underneath each other.

Step 2 Align the mounting holes on the bracket with the mounting holes in the equipment rack.

Step 3 Install the 12-24 or 10-32 screws through the elongated holes in the brackets and into the threaded holes in the mounting post. Repeat this step for the other side.

Installing the Adapters in the Cross Connect Drawers

The cross connect drawers for the Cisco ONS 15540 ESPx ship bare and require installation of the adapters into your cross connect panels. You must have these adapters for cross connecting cables in your system.

To install adapters into the cross connect panels, follow these steps:

Step 1 Open the cross connect drawer.

Step 2 Lock the drawer in the open position by pushing the lever at the back left of the drawer down into the locked position.

Step 3 Pull up the cross connect panel by flipping up the latches and using them to pull up the panel simultaneously.

Step 4 Remove the adapter from its packaging.

Step 5 Insert the adapter into the panel from the front.

Step 6 Flip the latches down and push the panel down when all desired adapters have been installed.
