Overview of the FESA
Overview of the FESA
The Fast Ethernet ServerNet adapter (FESA) is a single-port ServerNet adapter that
provides connectivity between NonStop S-series systems and Fast Ethernet 802.3u
LANs. It supports 100 Mbps and 10 Mbps Ethernet data transfer rates on NonStop
S-series systems. The FESA installs directly into a system enclosure that supports
multiple FESAs per system enclosure.
FESA Features
The features of the FESA are as follows:
•
Automatically adjusts (auto-sensing feature) to 100 Mbps or 10 Mbps operation
and can be easily added to an existing network on a NonStop S-series server.
•
Supports multiple communications protocols including TCP/IP, Expand/IP,
IPX/SPX, PAM, and SWAN (data transfer rate is reduced to 10 Mbps with SWAN).
•
Operates with your existing NonStop S-series network infrastructure, including
cabling (customer-supplied), protocol stacks, and user-written application code.
•
Retains the knowledge base of HP network administrators and users.
•
Is fully fault-tolerant with two-channel (ServerNet X and Y fabric) connections for
each adapter.
•
Ensures a virtually risk-free upgrade path to support higher performance on a
NonStop S-series server.
•
Supported by Tandem Service Management (TSM) client software to facilitate
diagnostics and maintenance.
•
A twisted-pair electrical interface is provided from the base product.
•
Offers 10 times the speed of 10 Mbps Ethernet at less than twice the price.
•
Supports new and existing bandwidth-intensive applications.
External Connectors and Indicators
The external connectors on an FESA are one 10/100Base-T RJ-45 type connector,
one debugging port, and one power interface. The debugging port is for manufacturing
only.
The external indicators consist of two status LEDs for the FESA, and six status LEDs
for the Fast Ethernet port. Figure 1-1 on page 1-4 shows the position of the external
connectors and indicators on the front of the adapter.
Note. FESAs (including FESA connections via S-series I/O enclosures) are not supported on
NonStop BladeSystems.
