Intrepid® 6140 Director Installation and Service Manual

General Information

When the IML button is pressed, held for three seconds, and

released, the director performs an IML that reloads the firmware from

FLASH memory. This operation is not disruptive to Fibre Channel

traffic.

When the RESET button is pressed and held for three seconds, the

director performs a reset. A reset is disruptive and resets the:

• Microprocessor and functional logic for the CTP card and reloads

thefirmwarefromFLASHmemory.

• Ethernet LAN interface, causing the connection to the

management server to drop momentarily until the connection

automatically recovers.

• Ports,causingall FibreChannelconnectionstodropmomentarily

until the connections automatically recover. This causes attached

devices to log out and log back in, therefore data frames lost

during director reset must be retransmitted.

A reset should only be performed if a CTP card failure is indicated.

As a precaution, the RESET button is flush mounted to protect

against inadvertent activation.

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

management 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. Directorfirmwareis upgradedconcurrently (withoutdisrupting

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.

Each card faceplate contains a green LED that illuminates if the card

is operational and active, and an amber LED that illuminates if the
