General Information
CTP2 Card
The director is delivered with two CTP2 cards. The active CTP2 card initializes and
configures the director after power on and contains the microprocessor and associated
logic that coordinate director operation. A CTP2 card provides an initial machine load
(IML) button on the faceplate. When the button is pressed and held for three seconds,
the director reloads firmware and resets the CTP2 card without switching off power or
affecting operational fiber-optic links.
Each CTP2 card also provides a 10/100 megabit per second (Mbps) RJ-45 twisted pair
connector on the faceplate that attaches to an Ethernet local area network (LAN) to
communicate with the HAFM server or a simple network management protocol
(SNMP) management station.
Each CTP2 card provides system services processor (SSP) and embedded port (EP)
subsystems. The SSP subsystem runs director applications and the underlying
operating system, communicates with director ports, and controls the RS-232
maintenance port and 10/100 Mbps Ethernet port. The EP subsystem provides Class F
and exception frame processing, and manages frame transmission to and from the
SBAR assembly. In addition, a CTP2 card provides nonvolatile memory for storing
firmware, director configuration information, persistent operating parameters, and
memory dump files. Director firmware is upgraded concurrently (without disrupting
operation).
The backup CTP2 card takes over operation if the active card fails. Failover from a
faulty card to the backup card is transparent to attached devices.
Each card faceplate contains a green LED that illuminates if the card is operational
and active, and an amber LED that illuminates if the card fails. Both LEDs are
extinguished on an operational backup card. The amber LED blinks if FRU beaconing
is enabled.
UPM Card
Each UPM card provides four full-duplex generic ports (G_Ports) that transmit or
receive data at 2.125 gigabits per second (Gb/s). G_Port functionality depends on the
type of cable attachment. UPM cards use nonopen fiber control (OFC) Class 1 laser
transceivers that comply with Section 21 of the Code of Federal Regulations (CFR),
Subpart (J) as of the date of manufacture.
