Introduction to the ServerNet Cluster Switch (Model 6770) ServerNet Clusters and External ServerNet Fabrics ServerNet Clusters and External ServerNet Fabrics The ServerNet Cluster Switch, model 6770, connects NonStop S-series servers in a ServerNet cluster. Dual (X and Y) external ServerNet fabrics provide fault tolerance for a ServerNet cluster. The peer external ServerNet fabric takes control if one external fabric fails.
Introduction to the ServerNet Cluster Switch (Model 6770) ServerNet Clusters and External ServerNet Fabrics Two switches per fabric support up to sixteen nodes (Figure 1-2) in a ServerNet cluster. Figure 1-2.
Introduction to the ServerNet Cluster Switch (Model 6770) ServerNet Clusters and External ServerNet Fabrics Three switches per fabric support up to twenty-four nodes (Figure 1-3) in a ServerNet cluster. Figure 1-3.
Introduction to the ServerNet Cluster Switch (Model 6770) Modular ServerNet Expansion Boards (MSEBs) Modular ServerNet Expansion Boards (MSEBs) The MSEBs route ServerNet packets out of each node and onto the external ServerNet fabrics. MSEBs are similar to system expansion boards (SEBs) but use plug-in cards (PICs) to provide a choice of connection media (ECL, fiber-optic, or serial copper). Fiber-optic ServerNet cables connect the MSEBs in each node to the ServerNet II Switches.
Introduction to the ServerNet Cluster Switch (Model 6770) • ServerNet Cluster Switch Enclosure AC Transfer Switch on page 1-10 provides dual power rails for the UPS and ServerNet II Switch. The ServerNet Cluster Switch is available in an enclosure or in an EIA standard rackmount (you must provide the rack). ServerNet Cluster Switch Enclosure When you receive a ServerNet Cluster Switch enclosure, the ServerNet II switch, AC transfer switch, and UPS are already installed inside the enclosure.
Introduction to the ServerNet Cluster Switch (Model 6770) EIA Standard Rack-Mount EIA Standard Rack-Mount The components of the ServerNet Cluster Switch: ServerNet II Switch, AC transfer switch, UPS, and a rack-mount kit are shipped separately to be installed at the customer site in a customer-supplied EIA standard rack.

Powering On and Powering Off a ServerNet Cluster Switch Powering On a UPS Powering On a UPS When AC power is available to the UPS from the AC transfer switch for the first time, a self test is initiated automatically. The front panel LEDs will go on and off during the self test. If the self test finishes successfully, the UPS enters Standby mode. Note. The self-test cannot be initiated if the batteries are less than 90% charged; a portion of the self-test requires battery power.
Powering On and Powering Off a ServerNet Cluster Switch Powering On a ServerNet II Switch Powering On a ServerNet II Switch Note. After powering off a ServerNet II Switch, you must wait 30 seconds before powering it back on again so that the voltage can discharge fully and that proper initialization can occur. If you do not wait 30 seconds, the ServerNet II Switch might power on in a non-operational state, and all LEDs will be stuck on. Powering off and back on again after 30 seconds corrects the problem.
Powering On and Powering Off a ServerNet Cluster Switch Powering Off a ServerNet Cluster Switch Powering Off a ServerNet Cluster Switch Powering Off a ServerNet II Switch You can power off the ServerNet II Switch from either the UPS or the ServerNet II Switch itself.

Verifying Proper Operation Troubleshooting Verifying Proper Operation If you detect a problem with a ServerNet Cluster Switch, use these procedures to verify proper operation. Verifying the AC Power 1. Check the LEDs on the AC transfer switch: a. Verify that all four green AC input LEDs on the AC transfer switch are lit. • • If these LEDs are lit, continue to the next step.
Verifying the Fabric LED on a ServerNet II Switch Troubleshooting 3. Check the LEDs on the ServerNet II Switch: a. Check that the green power-on LED on the ServerNet II Switch is lit. If this LED is not lit: a. Power-on the ServerNet II Switch again. b. Recheck the power-on LED. b. If the power-on LED on a switch continues to be unlit but the power-on LED 16 on the UPS and the AC transfer switch LEDs are lit, check the AC power cord from the UPS to the AC/DC power supply for the ServerNet II Switch.
Verifying the Connection Between a ServerNet II Switch and a Node Troubleshooting Figure 8-7. Fabric LED Indicator Attribute VST802.vsd Verifying the Connection Between a ServerNet II Switch and a Node For each node connected to a ServerNet II Switch: 1. Verify that the ServerNet port LEDs are lit. 2. Verify that the fiber-optic ServerNet cables are connected to the correct MSEBs: • • A ServerNet II Switch on the X fabric must connect to port 6 of the MSEB in group 01, module 01, slot 51.
Verifying the Connection Between ServerNet II Switches Troubleshooting connected to the correct port number, refer to Correcting the Cable Connections Between ServerNet II Switches on page 8-23. Note. Ports 8 and 9 are located to the right of ports 10 and 11. Topology ServerNet II Switch Connection from...

Troubleshooting Recovery Procedures Recovery Procedures If you encounter a problem with a ServerNet Cluster Switch, use the following procedures to recover. Recovery Procedures for the UPS Problems that might occur on the UPS include an audio alarm that sounds when a problem has occurred, or the UPS might not be in the correct mode for operation or replacement of the UPS or ServerNet II Switch.
Troubleshooting Recovery Procedures for the ServerNet II Switch Recovery Procedures for the ServerNet II Switch Problems that might occur on the ServerNet II Switch include an incorrectly set fabric LED or incorrect cable connections. Resetting the Fabric LED on the ServerNet II Switch If the Fabric LEDs are not correctly set on a ServerNet II Switch, reset the fabric LEDs: 1. From one of the nodes in the ServerNet cluster, log on to the OSM Service Connection or the TSM Service Application. 2.
Troubleshooting Recovery Procedures for the ServerNet II Switch 4. Inspect each fiber-optic cable connector. See Figure 8-8. • • • Make sure the ferrule housing and the ceramic ferrule tip are visible. The ferrule housing should be at least flush with the connector housing. It is normal for the ferrule housing to slide freely (approximately 2 mm) within the connector body between the stops designed into the connector body assembly.
Troubleshooting Recovery Procedures for the ServerNet II Switch 6. Insert the connector plug into the receptacle, squeezing the connector body gently between your thumb and forefinger as you insert it. Push the connector plug straight into the receptacle until the connector plug clicks into place.
