Base Station
The Base Station has five LEDs (see Figure 30 ).
Four LEDs on the left indicate error conditions
during power on, reset, and during the
diagnostic tests that run during normal
operation. The green LED on the right is the
power indicator.
Power On/Reset
Table 23 explains how to interpret Base Station
LED readings that occur during power on or
reset. The LEDs must be read in combination to
understand their meaning. The footnotes to the
table contain troubleshooting suggestions.
