Getting Help

This appendix describes how to troubleshoot the access server by referring to the LEDs on the rear panel of the chassis (see Figure 1-2) and on the feature cards. The feature card panels are shown in Figure B-1, Figure B-2, and Figure B-3.

Figure B-1 : T1 PRI Card Panel LEDs

Figure B-2 : E1 PRI Card Panel LEDs

Figure B-3 : 12-Port Modem Card LEDs

The LEDs indicate the current operating condition of the access server. You can observe the LEDs, note any fault condition that the product is encountering, and then contact your system administrator or a customer service representative, if necessary.

Chassis/Card LED State Description

Access server chassis Alarm On An alarm error has been detected.

AUI Flickering

Off The Ethernet LAN connection is transmitting and receiving data normally.
The Ethernet LAN connection is not transmitting or receiving data. Check the Ethernet cable connections.

Serial Flickering The associated serial port connection is transmitting and receiving data normally.

System Status (Located to the right of the Console/Auxiliary ports) Off
On
Blinking Power is off or system has not booted.
System is operating normally.
A memory failure has occurred.

Dual T1 PRI card Activity Flickering The CSU/DSU in the card is communicating with a remote CSU/DSU.

Board OK On The T1 PRI card has passed initial power up diagnostics tests and is operating normally

Loopback On A local or remote loopback diagnostic test is running on the associated T1 port.

Remote Alarm On A remote alarm indication signal (AIS) has been received on the associated T1 port. The AIS is received on loss of signal (LOS).

Local Alarm On The associated T1 port has detected local loss of signal (LOS) or out of frame (OOF) errors.

Dual E1 PRI card Activity Flickering The CSU/DSU in the card is communicating with a remote CSU/DSU.

Board OK On The E1 PRI card has passed initial power up diagnostics tests and is operating normally

Loopback On A local or remote loopback diagnostic test is running on the associated E1 port.

120 On Port is configured for 120 ohm line termination.

Remote Alarm On A remote alarm indication signal (AIS) has been received on the associated E1 port. The AIS is received on loss of signal (LOS).

Local Alarm On The associated E1 port has detected local loss of signal (LOS) or out of frame (OOF) errors.

12-Port Modem card ACT (Activity) Flickering The modem card is processing transmit, receive, and modem interrupts normally.

OK (Board OK) On

Off The modem card has passed the initial power-up diagnostic tests and is operating normally.
A fault condition is present on the card.

Running Diagnostic Tests

You can isolate problems on the dual T1 Primary Rate Interface (PRI) card with external test equipment to the RECEIVE jack to monitor signals coming into the RJ-48C port without interrupting normal data transmission. You can use the TRANSMIT jack to inject data, which interrupts normal data transmission.

Troubleshooting Network Interfaces

For information about isolating problems with the network connections to your access server, refer to the publication Troubleshooting Internetworking Systems available on the Cisco Connection Documentation CD-ROM.

Getting Help

For information about technical support, onsite service, and exchange and repair services, refer to the Cisco Information Packet that shipped with the access server.
