Chapter 3. Operation ARC-101 Installation & Operation Manual
3-2 Operating Procedure
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 on the
ARC-101 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.
Normal
Operation 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.
Turning off the
ARC-101 To turn off the ARC-101, disconnect the power cord from the mains outlet.
Procedure in
Case of
Malfunctioning 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.
