Indicators and Switches
The 9220 card can be installed in the 10-slot 8310 frame, or in the 20-slot 8321 frame. Prior to
installing the card, first install the corresponding rear I/O module. Note that the rear I/O module
for the 8321 frame is different from the module for the 8310 (8310 frame requires an RM-9220-
B rear I/O module; 8321 frame requires an RM20-9220-B rear I/O module).
Rear I/O Module Indicators
The 9220 rear I/O module is depicted below. It includes 6 ASI ports (configurable as inputs or
outputs) on standard BNC connectors, and two 100/1000 Mb/s Ethernet ports on standard RJ-45
connectors.
Each of the ASI ports has a green indicator LED, with the following states:
•
LED off: ASI port is disabled.
•
LED flashing once every 3 seconds: ASI port is configured as input, but it is not locked
to a signal (i.e., there is no input signal).
•
LED flashing once per second: ASI port is configured as input, and is locked to a
signal.
•
LED flashing multiple times per second: ASI port is configured as output.
Each of the Gigabit Ethernet ports has two indicator LEDs, with the following states:
•
Green LED:
o Off: No link
o On: Link
•
Yellow LED:
o Off: No activity (transmit and/or receive)
o Flashing: Port is currently transmitting and/or receiving
