Preparing to Install the Chassis

Chapter 2 Quick Installation Procedures

Installing Cisco ONS 15540 ESPx Hardware

Perform this procedure to install the Cisco ONS 15540 ESPx 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 #12-24 screws provided in the rack-mount kit. Use seven screws on each L bracket on the sides of the chassis. Start with the first screw at the top of the chassis and use a screw every two rack units to equally space the screws out and safely secure the chassis in the rack.

Installing the Chassis

Warning Only trained and qualified personnel should be allowed to install, replace, or service this equipment.

To install the 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 on the handles. With one person at each side of the chassis, use the handles on the chassis to slowly lift the chassis in unison.

Step 2 Position the chassis in the rack.

Step 3 Align the mounting holes in the L bracket with the mounting holes in the equipment rack.

Step 4 Use the 12-24 screws shipped with the chassis to mount the chassis in the rack. Use seven screws on each L bracket on the sides of the chassis. Start with the first screw at the top of the chassis and use a screw every two rack units to equally space out the screws and safely secure the chassis in the rack.

Step 5 Place the cable management tray over the fan assembly, ensuring that the tray is just under the chassis slots.

Step 6 If installing a cable management tray, secure the tray to the rack with four 12-24 screws, two on each side. To ensure correct placement of the tray, install the second of the two screws in the sixth slot up from the bottom of the chassis rack.

Note Test the cable management tray placement before cabling up the system.

Step 7 Attach the top cable management guide to the chassis just above the slots using the 12-24 screws. Make sure the grounding holes are visible through the top cable management guide.
