configuration data
Configuration data includes: identification data, port configuration data, operating
parameters, SNMP configuration, and zoning configuration. A configuration backup file is
required to restore configuration data if the CTP card in a non-redundant Director is
removed and replaced.
connectionless
Non-dedicated 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 to the
dedicated bandwidth that is required in a Class 1 Fibre Channel Service point-to-point
link.
connector
See optical fiber connector.
control processor card
Circuit card that contains the Director microprocessor. The CTP card also initializes
hardware components of the system after power-on. A 10 Mbps RJ-45 twisted pair
connector is located on the CTP card to connect to the Ethernet LAN and communicate
with the SDCM Server or a specific management station.
control unit
A hardware unit that controls the reading, writing, or displaying of data at one or more
input/output units.
control unit port
An internal Director port on the CTP card that communicates with the attached processor
channels to report error conditions and link initialization.
CRC
See cyclic redundancy check.
CTP
See control processor card.
CUP
See control unit port.
