Replace the LS-120 Drive

To replace the LS-120 drive, use the following procedure (see Figure 85). You can perform this procedure without powering down the router.

1. Remove the Routing Engine housing from the chassis, if it is not already. For instructions, see Remove the Routing Engine Housing.
2. Attach an ESD strap to your bare wrist and connect the strap to one of the ESD points on the chassis.
3. Locate the LS-120 drive module inside the Routing Engine housing. The drive resides in a metal housing in front of an equally sized hard drive.
4. Detach the exposed power connector plug and the Routing Engine connector from the top of the drive. You might need a small pair of pliers to grip the Routing Engine connector.
5. Using a Phillips screwdriver, unscrew the screws on the metal housing (three on each side).
6. Slide the LS-120 drive out of its bay.
7. Slide the replacement LS-120 drive into the empty bay.
8. Reattach the power connector and the Routing Engine connector.
9. Using a Phillips screwdriver, tighten the screws along both sides of the metal housing.
10. Return the Routing Engine housing to the chassis. For instructions, see Install the Routing Engine Housing.
