The EMS Console option is a Microsoft Windows Server 2003 feature that enables the Emergency
Management Console to be redirected through the serial port. When using iLO, select the value
(COM 1 or COM 2) assigned to the Virtual Serial Port). When redirecting EMS through a physical
serial port, select the value assigned to the Embedded Serial Port. The EMS Console feature is
disabled by default.
EMS provides input/output support for all Microsoft Windows kernel components: the loader,
setup, recovery console, OS kernel, blue screens, and the Special Administration Console. The
Special Administration Console is a text mode management console available after Windows
Server 2003 OS has initialized. For more information on EMS, go to the Microsoft website
(
www.microsoft.com ).
Microsoft enables EMS in the OS, but EMS must also be enabled in the ROM. EMS, when enabled,
assumes the serial port for redirection and may cause interference with other devices attached to
the serial port. To avoid interference, EMS is disabled in the system ROM by default on ML and
DL servers. If EMS is disabled in Windows Server 2003, perform the following steps to update the
boot.ini file:
1. Enable EMS in RBSU.
2. Run bootcfg/ems on/id 1 .
3. Reboot.
