supplies (BPS 0–5). Note that five BPS components is the minimum
requirement per cabinet, and six can be installed for redundancy.
The following fans are installed in each Superdome cabinet: four
blowers (0–3, at the cabinet’s top) and five I/O fans (0–4, inside the
cabinet above the I/O chassis).
See Figure 1-4 on page 22 for an overview of these items and their
locations.
• Utilities Components
Each HP Superdome server complex has two categories of utilities
boards: the boards that comprise the Guardian Service Processor
(GSP), and the clock, power monitoring, and cabinet-level utilities
board (UGUY).
Each Superdome cabinet has a UGUY board.
The GSP includes two types of boards: the SBCH, which provides the
interface to the Customer LAN (GSP network interface 0), and the
SBC, which provides the HP Private LAN (GSP network interface 1)
as well as the remote RS-232 port for modem access and the local
RS-232 port for direct access.
Each Superdome cabinet has an SBCH board, and in
Superdome 64-way server complexes only cabinet 0 has an SBC
board.
See Chapter 2 for details on using the Superdome console and
utilities interfaces.
• Service Management Station
The Service Management Station is an HP A-Class workstation that
is connected to the Superdome server for service and upgrade
purposes.
The Service Management Station is primarily used by HP service
personnel for firmware upgrades, system scan purposes, and
hardware verification purposes.
