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 |
