	3.1 Operating Procedure
Note	The interface modules are not hot-swappable. If you install or change
	modules, make sure to first disconnect power to the ARC-101, and then
	remove/install modules slowly and carefully (so as not to damage the modules
	or the ARC-101 enclosure). See section 2.6.

Turning off the ARC-101

Procedure in

Case of

Malfunctioning

Install the ARC-101 as described in Chapter 2. Make sure that the power cord is connected to the ARC-101's power connector on the rear panel. Plug the other end of the power cord into the mains outlet. The PWR indicator on the front panel should light.

Upon power-up, the ARC-101 goes through a self-test that takes about

40 seconds to complete. The FLT indicator is ON during the self-test. After the self-test is completed, if no faults have been detected, the FLT indicator is OFF. Detailed test results can e viewed from an ASCII terminal connected to the ARC-101's CONTROL port.

The ARC-101 operates unattended. During normal operation, the PWR indicators should light continuously, the FLT indicator should be OFF, the ATM indicator should light up when ATM traffic passes through the module, and the SYNC indicator should light up continuously.

To turn off the ARC-101, disconnect the power cord from the mains outlet.

The following table lists several common problems and their possible solutions.

The PWR LED does not light up	− Check the power cord connection on the back of the unit and at the
	mains outlet.
	− Verify power availability at the mains outlet.
Fault (FLT) LED blinks	− Unplug the unit (power OFF). Make sure that the modules are inserted
	properly. Tighten the modules' screws. Power ON the unit.
	− Using an ASCII terminal port, check for a fault indication in the
	Diagnostics window. If there is a fault, inform a qualified ARC-101
	technician.
Data transmission difficulties	− Ensure that the plugged-in modules are compatible with the protocol
	used (media, data rate).
	− Check the module's software configuration in the Configuration window.
	− Verify that the SYNC indicator is ON. If it is OFF (indicating a fault in the
	data reception link), run diagnostics on the remote unit from which data
	is being transmitted to the ARC-101. If it is BLINKING (indicating a fault
	in the data transmission link), run diagnostics on the remote unit, or
	implement a loop on the ARC-101 module, and verify that the
	SYNC LED is ON.
