5.3 LED STATUS MONITORS

The Model IM1/I features two LEDs that monitor general operating status and the 10Base-T twisted pair link integrity. Figure 4 (below) shows the LEDs located directly beneath the RJ-45 jack. Following Figure 4 is a description of each LEDs function.

Status

Blinks yellow from one to eleven times to indicate

 

system status. Each pulse pattern is separated by a

 

2 second “off” period. Greater pulse patterns have

 

higher priority (buffer saturation has greater priority

 

than an empty MAC table). Valid system statuses

 

are:

 

1 pulse = system status is okay

 

2 pulses = no MAC entries in the MAC Address Table

 

3 pulses = Clear to Send (CTS) or Carrier Detect

 

(DCD) from base unit are not asserted

 

4 pulses = IM1/I buffer is saturated

 

5 pulses = WAN receive frame(s) too large

 

6 pulses = WAN receive frame(s) not octet aligned

 

7 pulses = WAN receive frame(s) aborted

 

8 pulses = Detected WAN receive frame(s) with CRC

 

9 pulses = Detected LAN receive frame(s) too large

 

10 pulses = Detected LAN receive frame(s) not octet

 

aligned

 

11 pulses = Detected LAN receive frame(s) with bad

 

CRC

Link

Glows green to indicate good link integrity on the

 

10Base-T twisted pair line.
