15Figure 15 Installation procedureFigure 16 Removal procedureInstalling a power moduleCAUTION:• Follow the forward inertia of the power module when inserting it into the chassis, and make surethe power module has firm contact with the connectors on the backplane.• To prevent damage to the connectors inside the switch chassis, insert the power module gently.If you encounter a hard resistance while inserting the power module, pull out the power moduleand insert it again.• If only one power module is installed, install a power filler module in the empty power module slotfor good ventilation of the switch.To install an LSVM1AC300, LSVM1DC300, LSVM1AC650, or LSVM1DC650 power module into theswitch:1. Wear an ESD wrist strap and make sure it makes good skin contact and is well grounded.2. Unpack the power module and verify that the power module model is correct.3. Correctly orient the power module with the power module slot (see Figure 17), grasp the handleof the power module with one hand and support its bottom with the other, and slide the powermodule slowly along the guide rails into the slot.The slot is foolproof. If you cannot insert the power module into the slot, re-orient the powermodule rather than use excessive force to push it in.Figure 17 Installing a power module
