SAN32M1 Fabric Switch Installation and Service Manual 536
component
(1) Hardware or software that is part of a functional unit. (2) A func-
tional part of an operating system; for example, the scheduler or
supervisor (D).
concurrent firmware
upgrade
Firmware is upgraded without disrupting switch operation.
concurrent
maintenance
Ability to perform maintenance tasks, such as removal or replace-
ment of field-replaceable units (FRUs), while a hardware product is
operating.
configuration data The collection of data that results from configuring product and sys-
tem operating parameters. For example, configuring operating
parameters, simple network management protocol (SNMP) agent,
zoning configurations, and port configurations through the Element
Manager application, results in a collection of configuration data.
Configuration data includes: identification data, port configuration
data, operating parameters, simple network management protocol
(SNMP) configuration, and zoning configuration. A configuration
backup file is required to restore configuration data if the control pro-
cessor (CTP) card in a nonredundant ED-5000 Director is removed
and replaced.
connectionless Nondedicated link. Typically used to describe a link between nodes
which allows the switch to forward Class 2 or Class 3 frames as
resources (ports) allow. Contrast this with the dedicated bandwidth
that is required in a Class 1 Fibre Channel Service (FC-1)
point-to-point link.
connectivity The ability of devices to link together.
connectivity attribute In S/390 mode, the characteristic that determines port address status
for the director or switch. See

tion ; connectivity capability ; connectivity control ; dynamic connec-
tion ; dynamic connectivity ; unblocked connection .
connectivity capability (1) The capability that allows attachment of a device to a system with-
out requiring physical reconfiguration of either the device or the
interconnections. (2) The director or switch capability that allows log-
ical manipulation of link connections to provide physical device
attachment (D). See also

attribute ; connectivity control .
