SNMP
Simple Network Management Protocol.
Speed
A status type in the FC Status Menu showing the
speed (1063 Mbps) of the FC adapter.

Target
A SCSI device (usually the peripheral) that
responds to an operation requested by a SCSI
initiator (usually the host system). SCSI
peripherals are targets, but for some commands
(for example, a COPY command), the peripheral
may need to act temporarily as an initiator.
Terminator Block/Termination
An electrical connection at each end of the SCSI
bus composed of a set of resistors (or possibly
other components). Its function is to provide a
pull-up for open collector drivers on the bus, and
also impedance matching to prevent signal
reflections at the ends of the cable.
The SCSI bus requires termination at both ends of
the bus. One end of the SCSI bus is terminated by
the SCSI adapter’s internal termination. The other
end should have a terminator placed on the 68-pin
high density SCSI connector on the last SCSI
peripheral. If this device is not terminated, data
errors may occur.
Topology
The physical or logical layout of nodes on a
network. FC topologies include point-to-point, FC-
AL, and Fabric. The FCR200 supports all
topologies.
A status type in the FC Status Menu showing the
type of FC topology being used.
Trap
In the context of SNMP, an unsolicited message
sent by an agent to a management station. The
purpose is to notify the management station of
some unusual event.
