10 megohms (Mohms).

Replacing a Failed Hot-Swap Hard Disk Drive

To replace a 2.5-inch hot-swap SAS hard disk drive, complete the following steps.
You can order replacement hard disk drives from Cisco. The replacement part PID is
AIR-SRVR-146GB-HD=.
Step 1 Read the safety information in General Warnings, Regulatory and Safety, page 1-4.
Step 2 Touch the static-protective package that contains the drive to any unpainted metal surface on the
controller; then, remove the drive from the package and place it on a static-protective surface.
Step 3 Ensure that the drive you are replacing has failed before pulling it out of the drive slot. Press on the tray
handle to unlock the drive. Pull on the tray handle to remove the drive.
Step 4 Install the hard disk drive in the drive bay:
a. Make sure that the tray handle is in the open (unlocked) position.
b. Align the drive assembly with the guide rails in the bay.
c. Gently push the drive assembly into the bay until the drive stops.
d. Rotate the tray handle to the closed (locked) position.
e. Check the hard disk drive status LED to verify that the hard disk drive is operating correctly. If the
amber hard disk drive status LED for a drive is lit continuously, that drive is faulty and must be
replaced. If the green hard disk drive activity LED is flashing, the drive is being accessed.
