pmp-0049 (September 2012)
Module does not power on
To troubleshoot the failure of a module to power up, perform the following steps.
Procedure 17 Troubleshooting failure to power on
1
Verify that the connector crimps on the Ethernet cable are not loose.
2
Verify that the Ethernet cable is not damaged.
3
Verify that the cable is wired and pinned out according to the specifications provided in PMP
450 Installation Guide
4
Connect the power supply to a known good module via a known good Ethernet cable.
5
Attempt to power up the known good module and
if the known good module fails to power up, request an RMA for the power supply.
if the known good module powers up, return to the module that does not power up.
6
Reconnect the power supply to the failing module.
7
Connect the power supply to a power source.
8
Verify that the red LED labeled PWR lights.
9
If this LED does not light, and the module has not been powered up since the last previous
FPGA firmware upgrade was performed on the module, then request an RMA for the module.
Power supply does not produce power
To troubleshoot the failure of a power supply to produce power, perform the following steps.
Procedure 18 Troubleshooting failure of power supply to produce power
1
Verify that the connector crimps on the Ethernet cable are not loose.
2
Verify that the Ethernet cable is not damaged.
3
Verify that the cable is wired and pinned out according to the specifications provided in PMP
450 Installation Guide
4
Connect the power supply to a known good module via a known good Ethernet cable.
5
Attempt to power up the known good module.
6
If the known good module fails to power up, request an RMA for the power supply.
