system watchdog timer and reboot the system after a timeout, if the ASR feature is enabled. Otherwise,

error LED.
• Environmental monitor with fan speed control for temperature, voltages, fan failure, power supply failure,
and power backplane failure.

The TMM also provides the following remote server management capabilities through the ipmitool, a
management utility program:
• Command-line interface (IPMI Shell)
The command-line interface provides direct access to server management functions through the IPMI
2.0 protocol. Use the command-line interface to issue commands to control the server power, view
system information, and identify the server. You can also save one or more commands as a text file and
run the file as a script.
• Serial over LAN
Establish a Serial over LAN (SOL) connection to manage servers from a remote location. You can remotely
view and change the UEFI settings, restart the server, identify the server, and perform other management
functions. Any standard Telnet client application can access the SOL connection.
Using the remote presence and blue-screen capture features
The remote presence and blue-screen capture features are integrated functions of the TMM.
The remote presence feature provides the following functions:
• Remotely viewing video with graphics resolutions up to 1024 x 768, regardless of the system state
