5 • Troubleshooting and maintenance Model 6511RC User Manual

Introduction

This chapter provides guidance to assist you when performing troubleshooting and fault analysis as a Matrix Switch operator. Should you require more information or technical assistance, refer to chapter 6, “Contacting Patton for assistance” on page 101.

Troubleshooting during initial deployment

The following table (see table 5) describes the symptoms for system faults that commonly occur when the Matrix Switch is first deployed, along with suggested remedies for each fault.

Note The symptoms listed in table 5 apply to single-fault scenarios involv- ing the Model 6511RC. Performing the recommended corrective action will solve such single points of failure, but may not correct any additional faults that might co-exist. If you are unable to correct a failure in your Matrix Switch, refer to chapter 6, “Contacting Patton for assistance” on page 101.

Note When removing the 6511RC from the chassis, follow the procedures

	cited in section “De-activating the Model 6511RC” on page 80.
Note When re-inserting the 6511RC into the chassis, please follow the pro-
	cedures cited in chapter 2, “Hardware installation” on page 31
	Table 5. Symptoms
Problem	Corrective Action
POWER LED (green)	To verify that power is being supplied to the Model 6511RC via the CPCI chassis
is extinguished	power bus: verify that at least one chassis power supply module is installed in the
	chassis and functioning normally.
POWER LED (green) is	The 6511RC has detected a power failure on a power bus. There may be a prob-
flashing	lem with the CPCI chassis power system which feeds the Model 6511RC such as a
	failed power supply module in the chassis. The Model 6511RC will function nor-
	mally with one power supply. Inspect the power supplies in the CPCI chassis to
	identify and replace the failed power supply module. If no failed power supply is
	found, or if the POWER LED continues flashing, contact Patton Technical Support to
	determine if the Matrix Switch should be replaced.
CPU FAIL LED (red) is lit	CPU is unable to load the software from FLASH to RAM for operation. As soon as
	possible, remove the Model 6511RC from the CPCI chassis, wait 30 seconds, then
	re-insert the Model 6511RC into the CPCI chassis and see if the problem disap-
	pears. If the CPU FAIL LED remains lit after the Model 6511RC completes the
	power-up cycle, contact Patton Technical Support to determine if the Matrix Switch
	needs to be replaced.
ALARM LED (yellow) is	Indicates The 6511RC has detected a minor or major alarm condition. Examine
lit or flashing	the Alarm System Overview web management page to determine exactly which
	alarm(s) is(are) active.
