Chapter 2. Technical description 15
An EFC Server failure does not affect port connections or functions of an operational Director.
The only operating affect of a server failure is loss of remote access, configuration,
management, and monitoring functions.
Chapter 4, “Setting up the EFC Server environment” on page 35, and Chapter 5, “Configuring
the FICON Director” on page 45 discuss the EFC Manager functions in more detail.
2.1.4 Hardware components
Fiber Port Module (FPM) and Universal Port Module (UPM) cards
The port cards (FPM and UPM) are to provide the physical connectivity between the McDATA
Intrepid Director and the external connected devices.
򐂰 FPM
Each FPM card provides four full-duplex generic ports (G_ports) that transmit or receive
data at 1 Gbps. Single mode or multimode fiber optic cables attach to pluggable SFF
transceivers with LC-Duplex connectors.
򐂰 UPM
Each UPM card provides full-duplex generic ports that transmit or receive data at 1 Gbps
or 2 Gbps. UPM cards use non-open fiber control (OFC).
Each FPM or UPM faceplate contains a number of LEDs, as follows:
– An amber light (at the top of the card) illuminates if any port or other card circuitry fails,
or blinks if FRU beaconing is enabled.
– One amber LED and one green LED above each port, indicate port status as follows:
• The green LED illuminates (or blinks if there is active traffic) and the amber LED
goes out to indicate normal operation.
• The amber LED illuminates and the green LED goes out to indicate a port failure.
• Both LEDs extinguish to indicate a port is operational but not communicating with
an N_Port (no cable attached, loss of light, port blocked or link recovery in process).
• The amber LED flashes and the green LED either remains on, goes out or flashes
to indicate a port beaconing or running online diagnostics.
Control Processor (CTP)
The Directors are delivered with two CTP cards. The active card initializes and configures the
Director after power on and contains the microprocessor and associated logic that coordinate
Director operation. A CTP card provides an initial program load (IPL) button on the faceplate.
When the button is pressed and held for three seconds, the Director reloads firmware and
resets the CTP card without switching off power or affecting operational fiber-optic links
Each CTP card also provides a 10/100 megabit per second (Mbps) RJ-45 connector on the
faceplate that attaches to an Ethernet local area network (LAN) to communicate with the EFC
Server or a simple network management protocol (SNMP) management station. Each CTP
card must have a separate Ethernet connection to the EFC Server.
Each CTP 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 the
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
CTP card provides nonvolatile memory for storing firmware, Director configuration
information, persistent operating parameters, and memory dump files.
