HAFM Server Connectivity
The HAFM server provides an auto-detecting 10/100 Base-T Ethernet interface
that connects to a hub. Each director CTP card or switch front panel also provides
an auto-detecting 10/100 Base-T Ethernet interface that connects to a hub. A
12-port hub can be ordered from HP and installed at the top front of the equipment
rack.
Although directors provide two Ethernet connections to a hub, only one
connection is active at a time. The interface on the backup CTP card remains
passive until a failure on the active CTP card occurs, at which point the redundant
CTP card becomes active using the same media access control (MAC) address as
the original interface.
If an optional private intranet is to be used for LAN connections, an optional
Ethernet adapter card (not supplied by HP) can be installed in the Personal
Computer Memory Card International Association (PCMCIA) slot in the HAFM
server to provide a connection to a private LAN segment for dedicated director
communication.
The HAFM server uses a modem connection for service and support of managed
products. The modem provides a dial-in capability that allows HP-authorized
service personnel to communicate with the HAFM server and operate the HAFM
and Product Manager applications remotely.
The modem is also used to automatically dial out to an authorized support center
(to report the occurrence of significant system events) using a call-home feature.
The call-home feature is enabled in the Product Manager application and
configured through the dial-up networking feature of Windows 2000.
For directors and switches installed in some legacy environments, call-home
notification requires installation of HP Proactive Service software. This service is
offered at no additional charge for subsystems covered under an on-site warranty
or on-site storage hardware support contract. To register or order Proactive
Service software, contact your HP customer service representative.
