Installing the CDEs
Connecting Network Cables
Using the topology prescribed for the application, attach Ethernet cables to the Ethernet interfaces on
the SE and SR servers (see
Figure 2-1 and Figure 2-2 ).
In a system that uses SEs and SRs that are co-located, the Ethernet cables are used to make the following
physical connections between the following:
• SR to switch
•
SE to switch
•
CDSM to switch
Installing or Removing Disk Drives
The hard 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 hard drive from the chassis.
The hard drives on the CDE-100 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
Software Configuration Guide .
The CDE-100 contains four disk drives (see Figure 2-3 ) and the CDE-200 contains twelve disk drives
(see Figure 2-4 ).

To install a disk drive, perform the following steps:
Warning
During this procedure, wear grounding wrist straps to avoid ESD damage to the card. Do not
directly touch the backplane with your hand or any metal tool, or you could shock yourself.
