Verilink PRISM 3021 (CG) Configuration/Installation Guide - Manual

Front Panel Description
Index Item Function
1 STATUS If neither LED is On, the 3021 is not powered. If only the green LED is On, the 3021 is powered and may be functioning normally. If only the red LED is On, there
is a fault that exceeds alarm thresholds or another type of 3021 failure.
2 TD This green LED is On during a mark condition on the high-speed transmit data line.
3 RD This green LED is On during a mark condition on the high-speed receive data line.
4 RTS This green LED is On when the request-to-send signal is active.
5 DTR This green LED is On when the data-terminal-ready signal is active.
6 FAR/LOC
Switch This switch is used for local testing and setting the SUPV port rate when downloading firmware for the Flash PROM. For testing, setting the switch to LOC performs a network
LLB and setting the switch to FAR sends five seconds of in-band loop code and then sends the BERT pattern selected in the user interface. The default pattern is QRSS.
7 Activity
Indicators These two small, recessed LEDs indicate supervisory/network manager port activity.
8 SUPV Port The supervisory jack provides direct terminal access to control and monitor the 3021.
9 BV/CR/FE This LED is On when the unit detects bipolar violations, cyclic redundancy checking errors, or framing errors.
10 LOS/OOF This LED flashes when the unit detects a loss-of-signal condition or remains On during an out-of-frame condition.
11 AIS This LED is On when the network interface is receiving an alarm indication signal.
12 REM ALM This LED is On when the network interface is receiving a remote alarm indication.
13 LOOP This LED is On when the network interface is in a line loopback.
14 TST This LED is On when a BERT is in progress.
15 ERR This LED is On when BERT pattern errors are detected.
