Figure 4: Rear panel of Mongoose
1
Power IEC jack
– connects to AC line voltage, 100-240 V, 50-60 Hz.

The
Power
and
Locate
LEDs
on the back panel serve the same purpose as those on the front.
3
The
Ethernet Link LED
on the back panel serves the same purpose as the one on the front. The
Ethernet LAN LED
flashes when the Mongoose detects any Ethernet packets on the network.
4
The
CobraNet LEDs
(
In Use/Conductor
and
Link/Activity
) on the back panel serve the same
purpose as those on the front.
5
The
Remote Audio Devices LEDs
on the back panel serve a different purpose from the ones on the
front. The front panel LEDs provide information about signal activity on each audio channel. The
back panel LEDs indicate the health of the CAT 5 connection between each RAD and the Mongoose.
Just as on the front panel, these LEDs are numbered 1 through 8 which correspond to the numbered
ports on the device. Each LED corresponds with one twisted pair within the CAT 5 cable. If the
twisted pair is functioning properly, the LED displays a solid green light.
�
Audio Rx LED
– lights solidly if the Mongoose’s receive pair is working properly.
�
Audio Tx LED
– lights solidly if the Mongoose’s transmit pair is working properly.
�
Comm LED
– lights solidly if the RAD’s data communications pair is working properly.
�
Power LED
– lights solidly if the Mongoose is supplying adequate power to the RAD port.
6
Ethernet port
– used to connect the Mongoose to an Ethernet switch or directly to a computer.
Note that this Ethernet port contains auto-MDIX functionality, which means that if you connect
directly from this port to a computer, you can use either a standard Ethernet patch cable or a
crossover cable to make the connection. The auto-MDIX functionality takes care of coordinating the
proper connection between the devices.
7
CobraNet ports
– used to connect the Mongoose to another CobraNet-enabled device or to a
network switch. Use the
Primary
port to connect your primary CobraNet network. If you have a
backup CobraNet network, connect the Mongoose to it using the
Secondary
port. Both ports have
the same Media Access Control (MAC) address. Note that the CobraNet ports do NOT contain
auto-MDIX functionality. Therefore, if you use this port to connect the Mongoose directly to another
CobraNet device, you MUST use a crossover cable.
8
Remote Audio Devices ports
– used to connect each RAD to the Mongoose via a standard CAT 5
cable. You must use a standard Ethernet patch cable for this connection.
