This chapter describes how to troubleshoot the Cisco AS5400 and Cisco AS5400HPX universal

contains the following sections:
•
LEDs, page 4-1
• Mixing WAN DFCs, page 4-3
•
Environment Monitoring, page 4-4
• Using the Bantam Jacks for Test Port Functionality, page 4-7
•
Troubleshooting Network Interfaces, page 4-8
• Flash Memory Installation, page 4-8
•
Cisco AS5400HPX Images, page 4-8
• Getting Help, page 4-9
Note Unless specifically noted, all references to the Cisco AS5400 also apply to the
Cisco AS5400HPX.
Tips To help identify your universal gateway, starting with Cisco IOS Release 12.2(11)T, the
show version and show diag commands will identify the universal gateway as an AS5400
or AS5400HPX. Prior to this release, these commands showed the universal gateway as an
AS5400 , even if it was a AS5400HPX.
LEDs
The LEDs indicate the current operating condition of the universal gateway. 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 (see
“Obtaining Technical Assistance” in the Preface), if necessary.
Refer to Figure 4-1 to see the location of the LEDs. Refer to Table 4-1 for a description of the LEDs.
