Security features
• Administrator password and user password to help protect unauthorized access
to the server (see “Using passwords” on page 28)
• ThinkServer Trusted Platform Module (TPM), which is an integrated security chip,
to help enhance server security
• Remote monitoring or control by an administrator to provide protection or help
• Intrusion switch that informs you through an event in the system event log (SEL)
when the server cover is not properly installed or closed
Basic system management
features
• Ability to store the power-on self-test (POST) hardware test results
• BIOS Setup Utility program
The BIOS Setup Utility program helps you view the server information and
configure the server in the pre-operating system environment. See “Using the
Setup Utility program” on page 25.
• Preboot Execution Environment (PXE)
The Intel PXE technology enables you to boot your computers, load an operating
system, or deploy executable images from a remote server by using a network
interface. The operation can be done independently of local data storage devices
(such as hard disk drives) or operating systems.
• Redundant Array of Independent Disks (RAID)
Your server supports onboard SATA software RAID. If a required RAID card is
installed, your server also supports advanced SATA/SAS hardware RAID
configurations. For detailed information, see “Configuring RAID” on page 33.
• Software programs
For more information about the software programs, see “Software programs” on
page 9.
Operating environment
The following table provides information about the operating environment for your server.
Table 1. Operating environment specifications
Air temperature (operating) from 10°C to 35°C (50°F to 95°F)
Air temperature (storage) from -40°C to 60°C (-40°F to 140°F) in original shipping package
Humidity (operating) from 8% to 80% (non-condensing)
Humidity (storage) from 10% to 90% (non-condensing)
Altitude from 0 to 3048 m (0 to 10 000 ft) in an unpressurized environment
Note: When the altitude exceeds 3000 m (10 000 ft), the defined maximum dry-
bulb temperature for operation becomes a dependent variable. The temperature
value decreases by 1°C (1.8°F) per 300 m (984 ft) as the altitude increases.
