ED-64M Director Operating Features
FRUs accessed from the front of the director include the:
◆
Front bezel
◆
Control Processor (CTP) cards
◆
2 Gb Universal Port Module (UPM) cards
◆
Power supplies
Director FRUs accessed from the rear include the:
◆
Radio frequency interference (RFI) shield
◆
Input power module
◆
Cooling fan modules
◆
Serial crossbar (SBAR) cards
◆
Backplane (not shown)
CTP Card
The Control Processor (CTP) card initializes and configures the
director after the power is switched on, and contains the
microprocessor and associated logic that coordinate operation of the
director. An IML (Initial Machine Load) button and Ethernet
connector are built into the card’s faceplate. The faceplate also
contains LEDs to indicate the card’s operational status. For more
information, refer to CTP Cards on page 2-7.
The CTP card contains the 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 card.
In addition, the CTP card provides nonvolatile memory for storing
firmware (two memory regions), switch configuration information,
persistent operating parameters, and memory dump files. Because
two firmware versions can be stored on the card, firmware is
upgraded concurrently (without disrupting operation), even for a
single-CTP director.
A backup CTP card can take over operation if the active card fails.
Failover from a faulty card to the backup card is transparent to
attached devices. A backup CTP card can be added while the director
is powered on and operating.
