Data Sheet
The Cisco MCS 7825-H2 is a robust, highly available server platform designed to support today’s
IP Communications applications. It uses a single Intel dual-core Pentium D, 2.8-GHz or 3.4-GHz
processor with an 800-MHz FSB.
System-Health LEDs
The Cisco MCS 7825-H2 provides system-health LEDs and unit-identification lights on the front
and back of the server to make locating system problems easier than ever. When an internal
component fails, this indication is made on an internal-component LED (amber) and on the front
panel of the Cisco MCS 7825-H2. If the item can be serviced if the hood is removed, as in the case
of a fan failure, the internal-health LED illuminates. If no failures have occurred, the system-health
LED is green. If the failure is critical and has caused the system to shut down, the LED is red.
Redundant ROM
In the Cisco MCS 7825-H2, the ROM is divided into two logical parts. When the system boots, the
primary ROM side is executed and used in server operation. During a ROM flash, the backup side
is flashed. When the flash is fully completed, the backup side becomes the primary. If under rare
conditions the flash does not complete safely, potentially because of a power interruption, the
backup is available to boot the system. If both images are valid, the user can select which image
to use at boot time.
Serviceable SATA Disk Drives
The Cisco MCS 7825-H2 is configured with two 80-GB SATA “cold-pluggable” disk drives
configured in a RAID 1 mirror set. The server continues to operate if either of the two disk drives
fails. The SATA disk drives are accessible to the end user through openings in the front bezel of
the server. If a drive fails, the end user can schedule server downtime, power down the server, and
replace the failed SATA drive by simply removing it (each drive is equipped with a front latch that
positively mates the drive to the server) and replacing it with an unconfigured spare drive. After
restarting the server, the RAID 1 firmware initiates a remirroring of the new drive to help ensure
that drive redundancy on the Cisco MCS 7825-H2 is maintained. The serial-drive technology
introduced in the Cisco MCS 7825-H2 provides Cisco Systems customers with a highly reliable,
high-performance, cost-effective solution.
DAT Tape Drive Support
The Cisco MCS 7825-H2 can support an optional 36/72-GB USB external Digital Audio Tape
(DAT) drive (part number DAT-USB-EXT-72=) or an optional 36/72-GB USB rack-mount DAT drive
(part number DAT-USB-RM-72=), which connects through one of the four USB 2.0 ports provided
by the Cisco MCS-7825-H2 server.

Identifying Server CPU Speed
As the Cisco MCS 7825-H2 matures, the processor speeds will be changed as Intel retires slower
processors and replaces them with faster processors. Table 5 provides the Cisco manufacturing
part number shown on the chassis to help identify the processor speed of any individual server.
Table 5.
Manufacturing Part Numbers by Processor Speed
Manufacturing Part Number Located on

D, 3.4 GHz
Processor revision due to end of life of the 2.8-GHz
920 processor by Intel. This change is reflected in
the product ID of the MCS-7825-H2-IPC1 changing
to MCS-7825-H2-IPC2
