Cisco Systems NPE-175, NPE-225 manual Installing the NPE-G1 or NPE-G2 Cable-Management Brackets

Chapter 7 NPE-G1 and NPE-G2 Installation and Configuration Information

Installing the NPE-G1 or NPE-G2

Note The NPE-G1 or NPE-G2 is not fully seated in the router midplane until you tighten its captive installation screws.

Step 4 If you removed power supplies from the router, replace the power supplies. (See the “Removing and Replacing an AC-Input or DC-Input Power Supply” section on page 10-14when replacing a power supply in a Cisco 7200 VXR router.)

Step 5 If you slid the front of the router out of the rack, slowly guide the router back into the rack.

Step 6 Use a 3/16-inch flat-blade screwdriver to tighten the screws that secure the router to the front mounting strips of the rack.

This completes the procedure for installing the NPE-G1 or NPE-G2 in a Cisco 7200 VXR router.

Attaching the Rear Cable-Management Brackets and Cables (Optional)

You may choose to use one of two types of cable-management brackets. One type is the same as is used on the front of the router for managing port adapter and I/O controller cables. The NPE-G1- or NPE-G2-specific bracket is used only on the NPE-G1 or NPE-G2, and provides more support for optical fiber cables.

Depending on whether the router is front-mounted or rear-mounted in the rack, install the cable-management brackets to the router. Go to one of these sections for instructions on rear-mounting the cable-management brackets and attaching the cables:

•Installing the NPE-G1 or NPE-G2Cable-Management Brackets, page 7-29—This procedure applies to both the Cisco 7200 VXR routers and Cisco uBR7200 series routers.

•Installing the Rear Cable-Management Brackets on a Front-Mounted Router (Optional), page 7-31—This procedure applies to only the Cisco 7200 VXR routers.

•Installing the Rear Cable-Management Brackets on a Rear-Mounted Router (Optional), page 7-32—This procedure applies to only the Cisco 7200 VXR routers.

•Installing the Default Cable-Management Bracket on a Cisco uBR7246VXR Router (Optional), page 7-34—This procedure applies to only the Cisco UBR 7246VXR universal broadband router.

Installing the NPE-G1 or NPE-G2 Cable-Management Brackets

If you are using the NPE-G1 or NPE-G2 and installing the cable-management bracket (Cisco Product Number MAS-7200-CBLMGMT), use the following instructions. Figure 7-17illustrates installing the bracket on the NPE-G1 or NPE-G2 on the Cisco 7200 VXR routers. Figure 7-18illustrates installing the bracket on the Cisco uBR7200-NPE-G1 or Cisco uBR7200-NPE-G2 on the Cisco uBR7200 series routers.

Note The captive installation screws on the NPE-G1 or NPE-G2 must be fastened to allow the cable-management bracket to provide proper cable support and strain relief. Always ensure that the captive installation screws are properly tightened.
