HAFM Appliance Connectivity

The HAFM appliance 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
appliance to provide a connection to a private LAN segment for dedicated director
communication.
The HAFM appliance 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 appliance and
operate the HAFM and Element 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 Element 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.

Connectivity Planning Considerations

Directors, switches, and the HAFM appliance can be delivered in an HP-supplied
equipment rack in accordance with customer specifications. Consider the
