AT-MCF2000S Stacking Module

Problem 1: The Chassis ID number LEDs are off.

Solution: The AT-MCF2000S Module is not receiving power or has failed.

Try the following:

❒ Verify that the STATUS LEDs on the power supply modules in the

chassis are steady green. If the LEDs are off or signalling a fault

condition, refer to “AT-MCF2000AC and AT-MCF2300AC Power

Supply Modules” on page 150 for troubleshooting ideas.

❒ Verify that the AT-MCF2000S Module is fully seated in the

Management slot in the chassis.

❒ Remove and reinstall the AT-MCF2000S Module.

❒ Replace the module. If the replacement module works, the problem is

with the original module. If the replacement module does not work, the

problem is with the chassis.

Problem 2: A cable is connected to a Stack port but the port’s L/A LED is

off.

Solution: The Stack port is unable to establish a link with the Stack port in

the AT-MCF2000M Module or the AT-MCF2000S Module in the next

chassis. Try the following:

❒ Check that the cable is firmly connected to the Stack ports on both

chassis.

❒ Verify that the next chassis in the stack is powered on and is operating

properly.

❒ Verify that the cable does not exceed 100 meters (328 feet).

❒ Check that the cable is a standard straight-through or crossover TIA/

EIA 568-B-compliant Enhanced Category 5 (Cat 5e) shielded or

unshielded cable with 100 ohm impedance.
