Working with hot-swap ESM boards: Whenreplacing an ESM board, remember to do the following:1. Check the software documentation provided with yoursystem for instructions on ESM board failure-recoveryprocedures. Follow the steps provided in thesoftware documentation before continuing to step 2.2. Label each cable to ensure that all cables areproperly reconnected to the new ESM board.3. Label the GBICs when you remove them. You mustinstall the GBICs in the same positions on the newESM board.4. Remove the GBICs and FC cables from the failedESM board.NoteBe careful not to bend the FC cables at a sharpangle or pinch them with objects. This candecrease the performance or cause data loss.5. To remove the failed ESM board (the Fault indicatorlight is lit), push down on the latch. The levers willpop out of the locked position.6. Grasp the pull-rings and pull out on the levers, thenremove the ESM board.7. Set the tray numbers on the new ESM board tomatch the tray numbers on the failed ESM board.8. Install the new ESM board by sliding it into the emptyslot. Be sure the levers are pulled straight out as youslide the ESM board into the expansion unit.9. Close the levers until the pull-ring latch locks in place.Make sure the levers lock into place in theexpansion-unit chassis.10. Reattach the GBICs and FC cables to their originallocations.11. Check the Bypass LEDs at both ends of thereattached cables. If the Bypass LEDs are on,reattach the cables and GBICs.12. Check the Power and Fault indicator lights on thenew ESM board:If the Power indicator is off, the ESM boardmight not be inserted correctly.If the Fault indicator is lit, the Power indicatordoes not light, or any other Fault indicator is lit,refer to “Symptom-to-FRU Index” on page 71.13. Refer to your storage management software forinstructions on enabling the ESM board.Netfinity FAStT EXP500 - Type 3560 93
