This chapter provides configuration and troubleshooting information. Troubleshooting information includes general show commands, show and debug commands specific to the NSE-1, and error messages and the like. Instructions for removing a power supply for easier removal or installation of the network services engine are also provided. The following topics are covered in this chapter:
Network processing engines (NPEs) are not configurable. There are no tasks to perform.
The PXF processor is turned on by default. If it is ever disabled, you must enable it to take advantage of IP packet switching and feature acceleration.
![]() |
Note Before enabling the PXF processor, you must have IP routing and IP CEF switching turned on. |
To manually disable/enable the PXF processor, use the global commands:
hostname (config)# [no] ip pxf
The following features are supported by the PXF processor and are enabled using standard IOS procedures:
See the "Related Documentation" section to find documents about enabling these features.
Use the global show version or show c7200 commands to obtain information about the NPE or NSE, hardware, and software installed on your router. Examples of each follow.
Use the show version command to display the configuration of the system hardware including the NPE or NSE and the software version.

The weight of power supplies installed in a Cisco 7200 series router might make it difficult for you to pull the network processing engine from its chassis slot. If this is the case, first remove the installed power supplies from the chassis, and then remove the network processing engine. The following sections explain how to remove and replace an AC-input or a DC-input power supply in a Cisco 7200 series router.
![]() |
Note The network processing engine is installed above the power supplies in a Cisco uBR7200 series router. You do not need to remove the power supplies from a Cisco uBR7200 series router to pull the network processing engine from its chassis slot. |
![]() |
Caution Do not mix AC- and DC-input power supplies in the same router. |
The steps for removing an AC-input and DC-input power supply from a Cisco 7200 series router are the same. The two power supplies share the same dimensions and faceplates, except for the AC-input receptacle on the AC-input power supply and the DC-input lead receptacles on the DC-input power supply.
To remove an AC-input or DC-input power supply from a Cisco 7200 series router, complete the following steps:
Step 2 Using a number 2 Phillips or a 3/16-inch, flat-blade screwdriver, loosen the two captive screws on the faceplate of the power supply. (See Figure 7-1.)
If the router is not installed in a standard 19-inch, 4-post rack or in a telco-type rack, skip to Step 6. If the router is installed in a rack, determine if any permanent rack fixtures, such as a power strip, are obstructing access to the power supply. If a rack fixture is obstructing access to the power supply, proceed to Step 3.

Step 3 Using a 3/16-inch flat-blade screwdriver, loosen the screws that secure the router to the front mounting strips of the rack.
Step 4 Position at least one person in front of the rack to support the front underside of the router.
Step 5 From the rear of the rack, carefully push the front of the router out of the rack until there is enough clearance to remove the power supply.
Step 6 Grasp the power supply handle and pull the power supply from the router.
![]() |
Caution To maintain agency compliance requirements and meet EMI emissions standards for the Cisco 7200 series chassis with a single power supply, the power supply filler plate must remain in the power supply adjacent to the installed power supply. Do not remove this filler plate from the router unless you intend to install a redundant power supply. |
Step 7 Repeat Step 1 through Step 6 for the other installed power supply (if present).
This completes the procedure for removing an AC-input or DC-input power supply from a Cisco 7200 series router.
To install a new AC-input or DC-input power supply in a Cisco 7200 series router, complete the following steps:
Step 2 Grasp the power supply handle with one hand and place your other hand underneath the power supply for support. (See Figure 7-2.)

Step 3 Align the power supply to the power supply bay.
Step 4 Slide the power supply completely into the power supply bay until its faceplate is flush with the router's rear panel.
![]() |
Caution When inserting a power supply into the router, do not use unnecessary force; slamming the power supply into the bay can damage the connectors on the rear of the supply and on the midplane. |
Step 5 Seat the power supply in the router by tightening its captive screws with a number 2 Phillips or a 3/16-inch flat-blade screwdriver.
![]() |
Note The power supply is not fully seated in the router midplane until you tighten its captive installation screws (use a number 2 Phillips or a 3/16-inch flat-blade screwdriver). |
Step 6 Repeat Step 1 through Step 5 for a second power supply (if present).
Step 7 If there is no second power supply, replace the filler plate on the empty power supply bay. Using a number 2 Phillips or a 3/16-inch flat-blade screwdriver, tighten the filler plate's captive screws.
Step 8 If you pushed the router from the rack, slowly guide the router back into the rack.
Step 9 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 procedures for replacing an AC-input or DC-input power supply in a Cisco 7200 series router.
![]() |
Caution To maintain agency compliance requirements and meet EMI emissions standards for the Cisco 7200 series routers with a single power supply, the power supply filler plate must remain in the power supply adjacent to the installed power supply. Do not remove this filler plate from the router unless you intend to install a redundant power supply. |
