4-Port ServerNet Extender (4PSE)
Ethernet 4 ServerNet adapter (E4SA), Fast Ethernet ServerNet adapter (FESA), and
the Gigabit Ethernet ServerNet adapter (GESA), it cannot be installed in a NonStop
S-series enclosure.
A G4SA has three primary system connections:
•
Data transfer interface (ServerNet)
•
Maintenance entity (ME) interface
•
Power interface
The data transfer interface consists of ports to the ServerNet X and Y fabrics. The
ports connect to the ServerNet addressable controller (SAC) on the adapter. If one
ServerNet fabric fails, the G4SA can still be accessed using the remaining fabric.
The Maintenance Entity (ME) interface contains the circuitry required to meet the
maintenance system requirements of an active-logic adapter.
The G4SA receives power through a shielded, high-density, metric connector module.
The connector module provides attachments to the two ServerNet fabrics.
G4SAs are configured and managed through the Subsystem Control Facility (SCF)
interface to the ServerNet LAN Systems Access (SLSA) subsystem. The SLSA
subsystem is preinstalled and preconfigured and is started during the system-load
sequence.
For information about the SLSA subsystem, refer to the LAN Configuration and
Management Manual.
4-Port ServerNet Extender (4PSE)
A component in Integrity NonStop NS14000 and NS1000 systems only, 4PSEs provide
ServerNet connectivity between processors and the IOAM enclosure (functionality
provided by p-switches in an Integrity NonStop NS16000 system). 4PSEs are located
in slot one (and optionally slot 2) of each IOAM. They are connected to the processors
through LSUs in Integrity NonStop NS14000 systems, directly to the processors (with
no LSUs) in Integrity NonStop NS1000 systems. FCSAs and G4SAs can be installed in
slots 2 through 5 of the two IOAMs in the IOAM enclosure for communications to
storage devices and subsystems as well as to LANs.
See Monitoring the 4PSEs on page 8-7.
Monitoring I/O Adapters and Modules
Use the Subsystem Control Facility (SCF) or the OSM Service Connection to monitor
the FCSAs, G4SAs, and ServerNet/DAs.
