Troubleshooting Startup Issues Chapter 4 Troubleshooting Hardware Send documentation comments to [email protected] should immediately contact your customer service representative. (See the "Steps to Perform Before Calling TAC" section on page A-1.) There are no installation adjustments that you can make if the fan module does not function properly at initial startup. Note If you purchased Cisco support through a Cisco reseller, contact the reseller directly. If you purchased support directly from Cisco, contact Cisco Technical Support at this website: http://www.cisco.com/warp/public/687/Directory/DirTAC.shtm • Supervisor module-The supervisor module contains the operating system software, so check your supervisor module if you have trouble with the system software. Status LEDs on the supervisor module indicate whether or not the supervisor module can initialize a switching module. If you have a redundant supervisor module, refer to the following website for the latest Cisco MDS 9000 Family configuration guides for descriptions of how the redundant supervisor module comes online and how the software images are handled: http://www.cisco.com/univercd/cc/td/doc/product/sn5000/mds9000/index.htm. • Switching module-Status LEDs on each module indicate if it has been initialized by the supervisor module. A module that is partially installed in the backplane can cause the system to halt. SNMP Traps You can set SNMP traps to monitor fans, power supplies and temperature settings, or to test a call home application without risking adverse impact to your production SAN. Use any of the following commands to set SNMP traps: • test pfm test-SNMP-trap fan • test pfm test-SNMP-trap powersupply • test pfm test-SNMP-trap temp-sensor Note You do not have to physically remove the fan or power supply, nor do you have to physically increase the temperature, to generate these traps. Troubleshooting Startup Issues LEDs indicate all system states in the startup sequence. By checking the LEDs, you can determine when and where the system failed in the startup sequence. To identify startup problems, follow these steps: Step 1 Step 2 Turn on the power supplies by turning the switch to the on position (|). You should immediately hear the system fan module begin to operate. If not, see the "Troubleshooting Power Supply Issues" section on page 4-3. If you determine that the power supplies are functioning normally yet the fan module is faulty, see the "Troubleshooting Fan Issues" section on page 4-8.
