Configuration

LEDs

LEDs are visible on the unit's PCB between the reset button and the RJ-45 connector. The function of each
LED is described below:
LNK (green)
Green: On solid for an established 10BaseT or 100BaseT Ethernet Link.
SPEED
Green: Solid if 100BaseT, Blinks only if there is activity (TX or RX) on the network when a 100 MBit
connection is established. Off if a 10BaseT connection is established or if there is 10BaseT activity.
RSSI (4 LEDs)
Amber: Four LEDs
In all modes except "Survey", the unit's four yellow LEDs indicate the level of RF signal being
received from a VALID MU or RU as appropriate.
Yellow LED 1 : Begins blinking when RSSI is greater or equal to –90 dBm. On continuously at –85
dBm. This is the Leftmost LED
Yellow LED 2 : Begins blinking when RSSI is greater or equal to –80 dBm. On continuously at –75
dBm.
Yellow LED 3 : Begins blinking when RSSI is greater or equal to –70 dBm. On continuously at –65
dBm.
Yellow LED 4 : Begins blinking when RSSI is greater or equal to –60 dBm. On continuously at –55
dBm. This is the rightmost LED.
If no VALID MU or RU signal is detected the LEDs will not be on.
In addition, these 4 LEDs shall flash ON for 2 seconds, then OFF for 2 seconds to indicate the 'factory
reset' button has been activated and the reset successful.
ASSOCiation LED (green):
The ASSOC led blinks at the following rates:
- Once every second when unit is powered on but opmode is OFF.
- Twice per second while in opmode ON and scanning for an MU or RU.
- Solid after unit is associated with the RU or MU.
