SMART LOBE ACCESS UNIT
4. Operation
When all required connections are made (as
described in Chapter 3), the unit's operation
becomes completely automatic and unattended.
Upon request of the token-ring adapter card, the
Smart Lobe Access Unit inserts the corresponding
workstation into the network ring, lighting the LED
adjacent to the connector. When a workstation
removes itself from the active ring, the
corresponding LED turns off.
A flashing LED indicates that management has
disabled the lobe or that rate-detection circuitry
has detected a mismatch between the station bit
rate and the LAN bit rate or a physical disconnection
between the Access Unit and the MAU.
The 4M or 16M LEDs are ON depending on the rate
set by the rate-selection jumper.
