Basic TroubleshootingThis section describes the basic procedures that users should perform before undertaking a detailedtroubleshooting analysis of the Cisco UBR-RFSW-ADV or logging a case with the Cisco Technical AssistanceCenter (TAC).

Basic Troubleshooting ChecklistIf you encounter a problem after you install the Cisco UBR-RFSW-ADV, go through the followingtroubleshooting checklist to check for the most common error conditions before you contact the Cisco TACor before you perform a detailed troubleshooting analysis:

1 Is the power on?

2 Is the power supply securely inserted into the Cisco UBR-RFSW-ADV? Is the power supply connectedto a power source that is supplying voltage in the proper AC or DC range? Are all power leads and cablesfirmly connected at both ends?

3 Are the switch cards firmly seated and securely screwed to the Cisco UBR-RFSW-ADV?

4 Are all data cables firmly connected at both ends?

5 At power up, do the Cisco UBR-RFSW-ADV switch cards cycle through the green, blue, red LED colors?

After going through this checklist, go through the remaining sections in this chapter to verify the installationand to perform basic troubleshooting.

Confirming the Hardware InstallationStart troubleshooting the installation by executing the following commands. These commands display hardwarecomponents that are recognized by the system.

• show versionUse the show version command to confirm that the router is running the proper version of Cisco IOSsoftware and has a sufficient amount of system memory. The command also reports the system uptimeand the method by which the system was powered up.

In the following sample output from the show version command, some of the information may be usefulfor troubleshooting:UBR10K-ROUTER1# show version

If an installed item does not appear in the command output, make sure the item is properly installed. Forexample, make sure the switch cards are fully inserted into the slot and the captive screws are tightened. Ifthe problem persists, consult the Cisco UBR-RFSW-ADV release notes to confirm that this is not an existingproblem. Finally, contact Cisco TAC.

Check the following to help isolate a problem with the power system:

• Does the POWER LED illuminate green when system power is turned on? If not:

◦AC—Check to ensure that the AC power cord is plugged in to the power supply and the powersource (wall or power strip).

◦DC—Verify that the –48 and +48-V leads are correctly attached to the power supply.

◦Verify that the system is properly grounded.

• Verify the following sequence of events.

Alarm condition.Red

Only the upper LED is used for downstream switch cards.Note

Each upstream switch card has two LEDs and each downstream switch card has one LED to indicate theworking status of the port. The upstream switch module operates over the frequency range of 5 MHz to 85MHz. The downstream (high-frequency) switch module operates over the frequency range of 54MHz to 1002MHz. During normal system operation, upstream switches all direct traffic to their respective default terminationinterfaces.

The switch card should provide a minimum of 65 dB of isolation from connector port to connector port duringnormal operation and more than 65 dB when operating in protect mode.

When an upstream or downstream switch module initially boots, the LEDs briefly cycle on in sequence.

If you are unable to resolve the problem, see Obtaining Documentation and Submitting a Service Request forinformation on contacting Cisco technical assistance.
