Interpreting indicator lights
The activity of the MAX 800 unit’s indicator lights and how to interpret them depends on
which type of card is in use. You can interpret them when a PCMCIA card ISDN adapter is
inserted in the corresponding slot. Table 1-7 describes the PCMCIA card-related indicator
lights for a MAX 800 unit.
The MAX 800 unit’s back panel includes a link-status light that identifies the status of the
10BaseT Ethernet connection. If the light is on, a working connection exists between the MAX
Traffic light
The yellow Traffic light blinks to indicate that the unit has been
properly installed and is transmitting and receiving data across the
network.
PCMCIA cards
Each of the eight modem slots on the MAX 800 unit's back panel
has four corresponding lights on the front panel. The lights are:
•
ON—Power (green)
•
CD—Carrier Detect (red)
•
Rx—Receive data (yellow)
•
Tx—Transmit data (yellow)
These four lights provide status information that corresponds to
each of the eight PCMCIA cards optionally plugged into the unit.

Descriptions
ON
Each of the ON indicator lights shows whether the corresponding
modem is connected correctly and/or recognized by the MAX 800
unit. When this light is on, the modem is ready to receive data.
A flashing ON light means that the MAX 800 unit does not recog-
nize the modem but is going to attempt to receive data through it
anyway and interpret the data as Hayes-compatible modem com-
mands. This happens only when the modem is not on the approved
list or is malfunctioning. You can eject the questionable modem or
let the MAX 800 unit attempt to receive data through it.
CD
A CD light illuminates when an outside phone line connects to the
corresponding modem. The light remains illuminated until the
remote party disconnects from the line.
Rx
An RX light flashes when data is being received over the phone line
through the associated modem.
Tx
A TX light flashes when data is being transmitted over the phone
line through the associated modem.
