Guardian Service Processor (GSP) Overview
This section provides an overview of the Guardian Service Processor (GSP). The GSP is an always
on, dedicated service processor that monitors system power, cooling and configuration, and
provides console communications. Power and cooling information is obtained via an interface
to the platform monitor card. Configuration information is obtained via connection to the Serial
Presence Detect (SPD) bus. The GSP can only be installed in slot 2 and must be present for the
server to power up.
The GSP has downloadable firmware which can be updated independent of the HP-UX operating
system. GSP firmware updates can occur anytime the GSP is active. If the DC power switch is
OFF, the GSP is still operational and GSP firmware updates can still occur. GSP firmware updates
may be performed by customers.
If the GSP becomes hung, it is possible to reset the GSP without impacting the server. The GSP
may be reset via the GSP RESET button on the right side of the card. The PCI cover panel (right
side panel) must first be removed to allow access to the right side if the GSP card.
The GSP has two connectors on the bulkhead. An RJ-45 for LAN connections and a female DB25
connector for RS-232 connections. Attach either a "W" or an "M" cable to the DB25 connector to
provide individual output for CONSOLE, REMOTE and UPS.
To access the GSP from the local ASCII console, type control b and the GSP> prompt will appear.
It may be necessary to type control Ecf first. To exit the GSP, type GSP>co.
The GSP was originally a core component of the revision A rp5400 (A5576A) and rp5450 (A5191A)
servers. Beginning with introduction of the revision B rp5400 (A5576B), rp5450 (A5191B), and
rp5470 servers the GSP became a separate, must order product (A6696A).
There are two revisions of rp54xx GSP: rev A (A6696A) and rev B (A6696B). Both GSPs must be
installed in order for the server to power up.
