Appendix B IR-IP Interface Module Installation and Operation Manual

IR-IP LEDs

IR-IP contains three LEDs, which indicate the module activity. Table B-3explains the functions of the IR-IP interface indicators.

Table B-3. IR-IP Interface Indicators

LED Name	Function	Color
LINK	Lights when the Ethernet interface is connected to an active	Green
	LAN
ACT	Flashes when transmit and/or receive activity is present on the	Yellow
	Ethernet interface
ERR	Indicates erroneous events, such as collisions, buffer overflows,	Red
	etc. Also provides additional indications, described below in
	this section

Normal Indications

The IP router card can start normal service only after it has been configured for operation in the user’s network. To simplify the configuration procedure, when an unconfigured IP router card is powered on, it enters the configuration mode.

Power-Up Indications for Unconfigured IP Router Card

LINK indicator Lights steadily after power up when connected to an active station (10BaseT only).

ERR indicator Lights steadily for 12 to 15 seconds, until the card completes software decompression.

After this interval, the ERR indicator starts flashing rapidly (about 3 times per second), to indicate that the card is in the configuration mode.

Configuration instructions are described further in the appendix.

Power-Up Indications for Configured IP Router Card

LINK indicator Lights steadily after power up when connected to an active station (10BaseT only).

ERR indicator After software decompression, turns off.

Indications during Normal Service

During normal service, the LINK indicator lights steadily, indicating LAN integrity. The ACT indicator flashes in accordance with the Ethernet interface traffic.

The ERR indicator is normally off, however it may light momentarily from time to time, to indicate an occasional buffer overflow. If the ERR indicator lights often, the IP router configuration may have to be changed, e.g., it may need more main link bandwidth.
