ServerNet Adapters

An example of an enclosure with a GESA and a FESA installed follows:

Gigabit Ethernet 4-port

ServerNet adapter

(G4SA)

Provides Gigabit connectivity between NonStop S-series

systems and Ethernet LANs. The G4SA is a multiport

adapter with a copper and fiber interface, and it is a

field-replaceable unit (FRU). The G4SA is the only LAN

adapter supported for the I/O adapter module (IOAM)

enclosure. Although the G4SA supersedes the 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. The G4SA also provides

an open interface for an Asynchronous Wide Area

Network (AWAN) and ServerNet Wide Area Network

(SWAN) attachment to a ServerNet interconnect.

G4SA is supported by SNMP and WAN Wizard Pro.

The data transfer rate for SWAN is 10 Mbps and 10/100

Mbps for SWAN 2.

Multifunction I/O board

(MFIOB)

Provides several functions, including one Ethernet SAC

for the Ethernet port on the processor multifunction

(PMF) customer-replaceable unit (CRU). This port can

be used only by the system console. The MFIOB is a

ServerNet adapter that is integrated into the PMF CRU.

ServerNet/FX adapter Provides connectivity to an existing FOX ring. The

ServerNet/FX adapter is a field-replaceable unit (FRU).

The ServerNet/FX adapter uses the ServerNet/FX

adapter subsystem to deliver Expand-over-FOX

connectivity. Expand-over-FOX connectivity is described

in Section 5, Expand Network

Token-Ring ServerNet

adapter (TRSA)

Provides connectivity between NonStop S-series servers

and token-ring 802.5 LANs. It features one port per

board. The TRSA uses the SLSA subsystem to deliver

token-ring LAN access. The SLSA subsystem is

described in ServerNet LAN Systems Access (SLSA)

Subsystem on page 2-11.
