Configuring and Using Serial Over LAN 145
Configuring and Using Serial Over
LAN
Serial Over LAN (SOL) is an IPMI feature that allows a managed server’s
text-based console data that would traditionally be sent to the serial I/O port
to be redirected over the iDRAC’s dedicated Out-of-Band Ethernet
management network. The SOL out-of-band console enables system
administrators to remotely manage the blade server’s text-based console from
any location with network access. With SOL, you can:
• Remotely access operating systems with no timeout.
• Diagnose host systems on Emergency Management Services (EMS) or
Special Administrator Console (SAC) for Windows or in a Linux shell.
• View the progress of a blade server during POST and reconfigure the BIOS
setup program (while redirected to a serial port).
Enabling Serial Over LAN in the BIOS
To properly configure a server for Serial Over LAN, the following
configuration steps are required and will be explained in detail:
1
Configure Serial Over LAN in BIOS (disabled by default)
2 Configure the iDRAC for Serial Over LAN
3 Select a method to initialize Serial Over LAN (SSH, telnet, SOL Proxy, or
IPMI Tool)
4 Configure the operating system for SOL
