Name Function
AUI connector
Recessed slot
Serves as uplink port to network backbone.
Functions as compartment for housing recessed Mini MAU.
RJ45 connectors 24 ports; each can be connected to Ethernet device, including another hub for
daisy chaining.
AUI Uplink LED If active MAU is attached, this LED remains lit, indicating link exists and is
enabled
Partition LEDs 24 LEDs, indicating partitioned ports.
Link/Receive LEDs 24 LEDs, when lit, indicate link connection; when blinking, indicate packets
received on port.
Segment 1 LED
Segment 2 LED
With NMM Lite daughter board mounted, Segment 1 LED is lit; with AH2072
NMM board, either Segment 1 or Segment 2 LED is lit identifying segment to
which module is connected.
Neither segment LED is lit if module is not connected to segment. Note, even
when module is not connected to segment, repeater still functions.
