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 sat
uration has greater priority than an empty MAC table). Valid
system statuses are:
1 pulse = system status ok
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 = IMRC2/IA 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 bad 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
After a status code is displayed eight times and the associat-
ed condition is removed, the status code will no longer
appear.
Link
