4-Port ServerNet Extender (4PSE)
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 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 and connect to the processors via the LSUs.
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.
Monitoring the FCSAs
For a general, top-down approach for using OSM to monitor system components, refer
to Using OSM to Monitor the System on page 3-7.
To monitor the FCSA and its attached devices with SCF, use the SCF INFO and SCF
STATUS commands.
For example, to monitor all FCSAs using SCF:
> SCF STATUS ADAPTER $ZZSTO.#FCSA*, DETAIL
The SCF Reference Manual for the Storage Subsystem provides reference details and
examples for using the SCF INFO and SCF STATUS commands.
When monitoring FCSAs using the OSM Service Connection, the states of the FCSAs
should indicate normal operation. Table 8-1 lists the possible states for the FCSA.
