3.5.5 Trusted Platform Module (TPM)
TheSun Netra CP3250 blade server provides a Trusted Platform Module (TPM) chip,
which enables various security features, including hardware and software
authentication. This chip is reserved for future use on the Sun Netra CP3250 blade
server.
3.5.6 IPMC
The H8S/2166 IPMC provides the IPM controller function on the Sun Netra CP3250
blade server. The IPMC provides PICMG 3.0 board management functionality,and
interfaces to the payload through a serial interface.
The IPMC provides the following:
■Dual buffered IPMB interfaces to connect to IPMB-0
■Hot-swap latch input and LED control
■Payload power control
■Payload base and fabric interface e-keying control
■Payload power and temperature monitoring
3.5.7 RS-232 Serial Ports
A Serial port is available on the front panel using an RJ-45 connector.This same port
is also wired through the Zone 3 connectors to providea copy of this port on the
ARTM. This connector shares the SuperIO chip Port A with the H8-IPMI controller,
to allow console messages to be directedto the H8 when the external ports are not in
use. The blade server detects a valid RS232 connection to either the front or rearport
and will automatically disconnect the SuperIO port from the H8 and connect to the
external ports.
Note – The front and rearports cannot be used at the same time because they share
the same wires.
