E7S/7S Expansion Module

Supplement

304137-A Rev. 00

Ensuring a Successful Installation

After reconnecting the ARN to the network, you can ensure a successful upgrade

by checking the diagnostic LEDs on the front panel of the base module. See

Installing an Expansion Module in a BayStack ARN Router for the sequence of

front panel LED activity that should occur.

Interpreting the E7S Ethernet LEDs

Table 3 describes the LEDs for the E7S module’s Ethernet interface.

These LEDs will blink on and off during diagnostic testing, but they will not stay

on to indicate data transfer until you have configured the Ethernet interface.

Interpreting the E7S and 7S Serial LEDs

Each E7S and 7S received line signal detection (RLSD) LED lights when carrier

detect is present on the WAN port.
