Chapter 1 Overview
Power Up to two power supplies, both either 450W or 650W each.
Redundant as 1+1. Do not mix power supply types in the server.
See Power Specifications, page A-3 for more information on power supplies.
Cooling Five hot-swappable fan modules for front-to-rear cooling.
PCIe I/O Two horizontal PCIe
5
expansion slots on risers.
See Replacing a PCIe Card, page 3-33 for slot specifications.
Storage Drives are installed into front-panel drive bays that provide hot-pluggable access.
There are two versions of the server front panel and backplane:
• Small Form Factor—The server can hold up to eight 2.5-inch SAS
6
or SATA

hard drives or solid state drives.
• Large Form Factor—The server can hold up to four 3.5-inch SAS or SATA hard
drives.
The server also contains one internal USB 2.0 port on the motherboard that you can
use with a USB thumb drive for additional storage.
Cisco Flexible

The server can be ordered with an optional Cisco Flexible Flash drive (SD card).
This drive is pre-loaded with four virtual drives. The four virtual drives contain,
respectively, the Cisco Server Configuration Utility, the Cisco Host Upgrade Utility,
the Cisco C-Series server drivers set, and a blank virtual drive on which you can
install an OS or a hypervisor (see also
Replacing a Cisco Flexible Flash Card,
page 3-38).
