PA-E3 Receptacles and Cables

The two-port PA-2E3 port adapter has one status LED and six uplink port status LEDs (RCLK, FERF, OOF, AIS, RL, and LL) for each serial E3 port. (See Figure 1-4.)

LEDs

After system initialization, the ENABLED LED goes on, indicating that the port adapter has been enabled for operation.

The following conditions must be met before the PA-E3 port adapter is enabled:

•The port adapter contains a valid microcode version that has been downloaded successfully.

•For Cisco 7000 and 7500 series routers, the port adapter is correctly connected to the VIP2 and the midplane and is receiving power in the Cisco router.

•For the Catalyst 5000 family switches, the port adapter is correctly connected to the Catalyst RSM/VIP2 and is receiving power in the switch.

•The bus recognizes the port adapter.

If any of these conditions are not met, or if the initialization fails for other reasons, the ENABLED LED does not go on.

Table 1-1 describes the PA-E3 LEDs.

Table 1-1	PA-E3 Port Adapter LEDs
Name	Color	State	Description
ENABLED	Green	On	Indicates that the port adapter is ready.
Uplink port status
RCLK	Green	On	Indicates that a receive clock has been detected.
FERF	Yellow	On	Indicates that Framer detected Far End Receive
			Failure.
OOF	Yellow	On	Indicates that Framer detected Out of Frame.
AIS	Yellow	On	Indicates that Framer detected Alarm Indication
			Signal.
RL	Yellow	On	Indicates that port is in remote loopback mode.
LL	Yellow	On	Indicates that port is in local loopback mode.

PA-E3 Receptacles and Cables

The serial interface cable for the PA-E3, which is a 75-ohm coaxial cable, is used to connect your router to a serial E3 network. Serial cables conform to EIA/TIA-612 and EIA/TIA-613 specifications. The serial ports on the PA-E3 are considered to be DTE devices.
