Troubleshooting the Cisco UBR-RFSW-ADV
This chapter describes the troubleshooting procedures for the Cisco uBR Advanced RF Switch
(UBR-RFSW-ADV).

Basic Troubleshooting
This section describes the basic procedures that users should perform before undertaking a detailed
troubleshooting analysis of the Cisco UBR-RFSW-ADV or logging a case with the Cisco Technical Assistance
Center (TAC).
Basic Troubleshooting Checklist
If you encounter a problem after you install the Cisco UBR-RFSW-ADV, go through the following
troubleshooting checklist to check for the most common error conditions before you contact the Cisco TAC
or 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 connected
to a power source that is supplying voltage in the proper AC or DC range? Are all power leads and cables
firmly 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 installation
and to perform basic troubleshooting.

Confirming the Hardware Installation
Confirming the Hardware Installation
Start troubleshooting the installation by executing the following commands. These commands display hardware
components that are recognized by the system.
• show version
Use the show version command to confirm that the router is running the proper version of Cisco IOS
software and has a sufficient amount of system memory. The command also reports the system uptime
and 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 useful
for troubleshooting:

If an installed item does not appear in the command output, make sure the item is properly installed. For
example, make sure the switch cards are fully inserted into the slot and the captive screws are tightened. If
the problem persists, consult the Cisco UBR-RFSW-ADV release notes to confirm that this is not an existing
problem. Finally, contact Cisco TAC.
Hardware Troubleshooting Flowchart
Use the figure below to determine which component of your Cisco UBR-RFSW-ADV is malfunctioning.
This figure describes a series of hardware-dependent startup events that must take place for a Cisco
UBR-RFSW-ADV to allow the passage of traffic. At each main point of the flowchart, there are pointers to
the chapters in this guide that describe how to troubleshoot individual pieces of hardware.

◦Lower LEDs cycle through green, red, and blue; then turn off.
◦Upper LEDs cycle through blue, green, red, and blue.
◦All LEDs turn the appropriate color (green for working, blue for protect, or red for alarm).

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 power
source (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.

Only the upper LED is used for downstream switch cards.
Each upstream switch card has two LEDs and each downstream switch card has one LED to indicate the
working status of the port. The upstream switch module operates over the frequency range of 5 MHz to 85
MHz. The downstream (high-frequency) switch module operates over the frequency range of 54 MHz to 1002
MHz. During normal system operation, upstream switches all direct traffic to their respective default termination
interfaces.
The switch card should provide a minimum of 65 dB of isolation from connector port to connector port during
normal 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.
