Installing or Removing Disk Drives

The disk drives for the CDEs are shipped separately. You must install the disk drives before using the
CDEs. A minimum of two disks are required for basic software installation (needed for the RAID-1 set).
If the CDE is used to store content (configured as an SE), more than two disks are needed.
For maintenance or other reasons, it may become necessary to remove a disk drive from the chassis. The
disk drives on the CDE100 are monitored using Self-Monitoring, Analysis, and Reporting Technology
(S.M.A.R.T.) and statistics are displayed through the Administrative Interface, as well as sent to the
CDSM. For more information about S.M.A.R.T., see the Cisco Internet Streamer CDS 2.0-2.1 Software
Configuration Guide.
