AT-810SL Multiport Transceiver Fanout User Manual
13
The AT-810SL back panel has two categories of LEDs:
❑
On Line — Each Transceiver Port has an associated On-line LED.
When illuminated, these LEDs indicate that power is applied to the
DTE which is connected to the related port through the AUI cable.
These LEDs will be illuminated (or not illuminated) regardless of the
AT-810SL’s operational status. They allow a DTE’s “in use” status to
be noted before disconnection of its cable.
❑
System Power — When illuminated, this LED indicates AC power is
correctly applied and the internal power supply is operational. This
LED is redundant to the System Power LED which is located on the
front panel.
Cascading
As previously stated, your AT-810SL can be used to cascade other devices.
Using up to eight multiport transceivers in this configuration allows a
maximum of 64 DTE (workstations) to be interconnected.
A cascaded series of multiport transceivers can be operated as an independent
network or connected to other segments through an optional ATI CentreCOM
transceiver.
The following figure illustrates eight CentreCOM Multiport Transceiver
Fanouts cascading to provide up to 64 DTE (workstation) connections from one
MAU tap on a coaxial backbone.
Figure 9 shows the AT-810SL functioning with a backbone transceiver fanout.
