LEDs
The LEDs indicate the current operating condition of the Cisco AS5350. 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 the “Obtaining Technical Assistance” section on page xiv), if
necessary. Refer to Figure 4-1 for a diagram illustrating the rear panel LEDs and Table 4-1 for a
description of the LEDs.
For information about LEDs and troubleshooting on Cisco AS5350 dial feature cards, see the
Cisco AS5350 Universal Gateway Card Installation Guide. This document is available on the World
Wide Web and the documentation CD-ROM that comes with your universal gateway. (See the “Obtaining
Documentation” section on page xiii.)
