Chapter 4: Troubleshooting

❒
Verify that the power from the power source is within the operating
specifications of the power supply module, listed in “Power
Specifications” on page 88.
❒
Replace the power supply module.
Problem 4:
The FAN LED in the LED panel is amber.
Solution:
A fan in the power supply module has failed. Replace the
module.
Problem 5:
One or both power supply modules shutdown.
Solution:
Try the following:
❒
Check to be sure that the chassis is not overheating. Verify that it has
adequate ventilation and that the fans on the power supply modules
and the ventilation vents on the front panel of the chassis are
unobstructed.
❒
Verify that the module is not connected to two high-power x610
Switches or one low-power and one high-power switch. It may have
shutdown because the power requirements of the switches exceeded
its power reserves. A power supply module can support two low-power
switches or one high-power switch at a time.
Problem 6:
You are unable to install a second module in the chassis
because the faceplates of the new and existing modules do not align.
Solution:
The faceplates of the power supply modules are keyed to
prevent the installation of incompatible modules in the chassis. You may
not install the AT-PWR250 Power Supply Module in the same chassis as
the AT-PWR800 or AT-PWR1200 Module. For more information, refer to
“Power Supply Modules” on page 19.
Problem 7:
The chassis is not providing PoE+ power to an PoE+ x610
Series switch.
Solution:
Try the following:
❒
Verify that the x610 Series switch supports the PoE+ feature. The
model name on the front panel of the switch should contain the letters
“POE+.” Switches whose model names do not include the letters do
not support PoE+.
❒
Verify that the AT-RPS-CBL1.0 cable from the x610 Series switch is
securely connected to RPS port 2 or 4, PoE+/System, on the chassis.
❒
Verify that the chassis has a power supply for the RPS port to which
the switch is connected. For example, if the switch is connected to
RPS port 4, slot B of the chassis has to contain either an AT-PWR800
or AT-PWR1200 Module.
