Server Board S5500BC TPS Platform Management
Revision 1.8 Intel order number: E42249-009 51
SOL Found Active: The BIOS prioritizes SOL over Serial B Console Redirection. The
BIOS queries the BMC for SOL Baud Rate and overrides the setup Serial B Console
Redirection Baud with SOL Baud Rate.
The BIOS also enables Hardware Flow control between the BIOS and BMC and forces
terminal emulation type as PC-ANSI.
Since Serial B is a shared port between the BIOS and BMC, if SOL is found active, the
user sees no data on Serial B port.
Note: The SOL override settings are only valid for the current BIOS boot. On the next boot, if
SOL is not found active, the BIOS uses the Console Redirection settings set by the user and
performs Console Redirection either on Serial A or Serial B port.
Case II:
Console Redirection is enabled on Serial A with Baud = 115200, Flow Control=CTS-RTS,
Terminal Type =VT100.
The BIOS sends data on Serial A port with 115200 Baud, flow control CTS-RTS enabled
and emulates the terminal Type as VT100. In summary, the BIOS uses the setup settings
and performs Console Redirection on Serial A.
Legacy Console Redirection:
The BIOS enables Legacy Operating System redirection on Serial A or Serial B,
depending upon the BIOS settings. Legacy Operating System redirection happens at the
same Baud, Flow Control and Terminal Type set by the user.
SOL Found Active: If SOL is found active, then the BIOS overrides the BIOS settings and
AUTO enables Legacy Operating System redirection on the SOL console.
4.4 Node Manager
4.4.1 Overview
Node Management (NM) provides the system with a method of monitoring power consumption
and thermal output, and adjusting system variables to control those factors. As opposed to
component-level power/thermal solutions (such as Demand Based Switching), Node
Management functions at the platform level.
NM is only available on platforms that support PMBus-compliant power supplies. The BMC
supports NM specification version 1.5. Additionally, the platform chipset must have an NM-
capable Management Engine (ME).
4.4.2 Command Bridging
The majority of BMC functionality to support the NM is handled by bridging commands and
