HP NonStop NS manual Monitoring I/O Adapters and Modules, Port ServerNet Extender 4PSE

I/O Adapters and Modules: Monitoring and Recovery 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.
