Each BladeCenter HS20 has an integrated service processor on-board that communicates
with the BladeCenter Management Module to enable blade server management remotely
(see 1.2.3, “BladeCenter Management Module” on page 8 for more details on the
management module). The service processor provides the following functions:
Loader and OS Watch Timer
Remote soft shutdown
POST Watchdog Timer
Light Path support
VPD support
PFA for VRM/CPU/Memory/HD
Numeric based Error log
ASM interconnect support (RS485)
Environmental querying and alerts (TEMP/Voltages)
Automatic Server Restart
Remote Power On/Off
In-band support for UMS/Director
I2C interface to core logic (CSB5 chip)
Local Environmental Monitoring
Local LED control
RS-485 interface to the Management Modules
The BladeCenter HS20 also has two integrated Ethernet controllers for redundancy. If
redundancy is required, you must install Ethernet switch modules in switch module bays 1
and 2 (see 1.2.6, “BladeCenter 4-Port Ethernet Switch Module” on page 12 for more details).
