- Verify that both the compute module and the client are connected to the correct physical LAN and VLAN? • Is the power LED lit on the Ethernet switch module? - If not, try to re-seat the switch module - If so, check the fault LED on the switch module • Is the power fault LED lit on the Ethernet switch module? - If so, check the status of the system using the Intel® Modular Server Control. - If not, check the switch port link. • Is the switch connected to the network by way of an Ethernet cable? - If not, connect the switch to the network. - If so, verify that the link light is lit for the connected port. • Is the link light lit for the connected port? - If not, move the Ethernet cable to a different port. If the link light on the other port does not light, replace the cable. If the switches and connections are correct and AC power is available at the wall outlet, contact your service representative or authorized dealer for additional help. Cannot Connect a Compute Module to a Storage Control Module Check the following: • Verify that storage space in the storage control module has been allocated for and assigned to the compute module. • Make sure the drive(s) assigned to the compute module are installed and operating properly. • Make sure the installed drives are validated for use with the Intel® Modular Server System MFSYS25/MFSYS35. Refer to the Intel® Modular Server System Tested Hardware and Operation System List for validation information. • Check the status of the system using the Intel® Modular Server Control. Diagnostic LED Information The various modules and compute modules designed for use with the Intel® Modular Server System MFSYS25/MFSYS35 provide a number of diagnostic LEDs that may aid in troubleshooting your system. A list of these LEDs, with usage descriptions for each LED, is provided in the following two tables. Intel® Modular Server System User Guide 141
