Installing the Chassis

Chapter 2 Quick Installation Procedures

Installing Cisco ONS 15540 ESP Hardware

Perform this procedure to install the Cisco ONS 15540 ESP chassis in a standard 19-inch rack:

Step 1 Place the L brackets on the sides of the chassis.

Step 2 Secure the L brackets to the chassis using the 14 M4 Phillips countersunk-head screws provided in the rack-mount kit. Use seven screws on each L bracket on the sides of the chassis.

Step 3 Place the top cable guide over the top of the chassis. Ensure that the earth contact is visible through the cable guide.

Step 4 Secure the cable guide to the shelf with five 6-32 screws.

To install the Cisco ONS 15540 ESP chassis in the rack, follow these steps:

Step 1 Grasp the bottom edge of the chassis with one hand near the front and the other near the back. With one person at each side of the chassis, slowly lift the chassis in unison.

Step 2 Position the chassis in the rack.

Step 3 Align the mounting holes in the L bracket and the bottom cable management guide with the mounting holes in the equipment rack.

Step 4 Install the 12-24 or 10-32 screws through the elongated holes in the L bracket and into the threaded holes in the mounting post.

Step 5 Place the bottom cable guides over the fan assembly.

Step 6 Secure the cable guide to the rack with the 6-32 screws.

Installing Strain Relief Brackets

The Cisco ONS 15540 ESP system uses a power supply cable strain relief bracket for connections to its power supply and an alarm cable strain relief bracket for alarm cable connections. The strain relief brackets must be installed after the shelf is rack mounted and installed in the rack. The brackets are required for proper function of the power supply and alarm cables.

To install the strain relief brackets, follow these steps:

Step 1 Place the strain relief bracket over the designated slots on the back panel.

Step 2 Use the two screws provided to secure the strain relief bracket to the shelf.

Installing the Processor Card

The mux/demux motherboards, line card motherboards, and processor cards are hot-swappable. We recommend installing the processor cards first and then filling the chassis from slots 0 to 11, left to right.
