Ctp Card - HP Surestore 64 - Director Switch Planning Manual

The system error LED illuminates when the director detects an event requiring immediate
operator attention, such as a FRU failure. The LED remains illuminated as long as an event
is active. The LED extinguishes when the Clear System Error Light function is selected
from the Product Manager application. The LED blinks if unit beaconing is enabled. An
illuminated system error LED (indicating a failure) takes precedence over unit beaconing.

CTP Card

The director is delivered with two CTP cards. The active CTP 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 machine load (IML)
button on the faceplate. When the button is pressed and held for three seconds, the
director reloads firmware and resets both CTP cards without switching off power or
affecting operational fiber-optic links.
Each CTP 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 HP EFC Server or a simple network management protocol (SNMP)
management station.
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
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. Director firmware is
upgraded concurrently (without disrupting operation).
The backup CTP card takes over operation if the active card fails. Failover from a faulty
card to the backup card is transparent to attached devices. A failed CTP card should be
replaced while the director is powered on. This ensures correct transfer of the firmware
image and configuration information.
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.
