Removing controller canisters from a controller-drive trayWhen you remove a controller canister, you must disconnect all cables and remove any SFPtransceivers. Then, you can slide the controller canister out of the controller-drive tray.About this taskAttention: Possible hardware damage – To prevent electrostatic discharge damage to the tray,use proper antistatic protection when handling tray components.Steps1. Put on antistatic protection.Attention: Potential degraded performance – To prevent degraded performance, do not twist,fold, pinch, or step on the cables. Many cables have a minimum bending radius. Check thespecifications for your cables, and do not bend any cable tighter than the minimum specifiedradius.2. Label each cable that is attached to the old controller canister. Depending on the HICconfiguration, you might be able to reconnect some cables after you replace the controllercanister.3. Disconnect all of the interface and Ethernet cables from the old controller canister.If fiber-optic cables are present, you can use the two release levers to partially remove thecontroller canister. Opening these release levers makes it easier to press down the fiber-opticcable release tab.4. If the old controller canister contains a Fibre Channel HIC or an InfiniBand HIC, remove thesmall form-factor pluggable (SFP+) transceivers (for Fibre Channel) or quad SFP (QSFP+)transceivers (for InfiniBand) from the HIC, and save them for possible reuse.5. Remove controller A.a. Unlock and rotate the release handles out to release the controller canister.b. Using the release handles and your hands, pull the controller canister out of the controller-drive tray.The following figures show the release handles for the E2612 and E2624 controller-drive traysand the E2660 controller-drive tray. The other controller-drive trays have a similar configurationfor the release handles.13
