Overview CTP2 Card The Director 2/64 ships with two Control Processor (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. The second CTP2 card serves as a backup. 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). Each CTP2 card provides System Services Processor (SSP) and Embedded Port (EP) subsystems. The SSP subsystem runs director applications, communicates with director ports, and controls the RS-232 maintenance port and 10/100 Mbps ethernet port. The EP subsystem provides Class F processing, and manages frame transmission to and from the Serial Crossbar Assembly (SBAR). In addition, CTP2 cards provide non-volatile memory for storing firmware director configuration information, persistent operating parameters, and memory dump files. Director firmware is upgraded concurrently (without disrupting operation). Each card faceplate contains a green light emitting diode (LED) that turns ON if the card is operational and active, and an amber LED that turns ON if the card fails. The LEDs are OFF on the backup CTP2. The amber LED FLASHES if beaconing is enabled. Front Bezel The bezel at the front of the Director 2/64 includes two indicator LEDs. The green power LED turns ON when the director is powered on and operational. If the LED turns OFF, a facility power source, alternating current (AC) power cord, or director power distribution failure is indicated. The amber system error LED turns ON when the director detects an event requiring immediate operator attention, such as an FRU failure. The LED remains illuminated as long as an event is active. The LED FLASHES if unit beaconing is enabled. 28 Director 2/64 Installation Guide
