RTM4808 Rear Panel Transition Board

¤U¸üPDF

Product PhotoThis single-slot, 6U board provides rear panel access to the I/O functions of an IPnexus™ single board computer (SBC) with RPIO-pin compatibility, such as the IPnexus ZT 5504e System Master Processor Board. It is also designed to function with other third-party PICMG® 2.16-compliant SBCs. The IPnexus RTM4808 easily snaps into the rear panel slot of a 6U PICMG 2.16-compliant CompactPCI® system such as the IPnexus ZT 5091e 4U Packet-Switched Platform.

The RTM4808 routes all cabling out the back of a system and provides access to a secondary IDE channel, Com1 and 2 serial ports and a floppy disk drive. It allows for trouble shooting and servicing of a system without disruption of the processor board, thus enhancing the reliability and availability of the system, particularly while running diagnostics or conducting maintenance.

Highlights

Key Design Elements

Ethernet

The RTM4808 provides two rear panel RJ-45 Ethernet connectors that connect to the host SBC through the RPIO connector J3.

Input/Output

The RTM4808 provides two RS-232 serial port connectors and a PS/2-style keyboard/mouse port (requires a 'Y' splitter cable). Rear panel access is provided to the VGA video and USB signals on the host SBC.

Internal Interfaces

An internal IDE channel supports two IDE devices simultaneously or one IDE device when a Type I/II CompactFlash® expansion card is installed. A special 40-pin, 80-conductor cable is necessary for IDE device connection. Power for the IDE device can be drawn from an on-board power connector at J8 when supplemental power is supplied to power connector J9. Two LEDs on the front plate indicate hot-swap and IDE device activity. The hot-swap LED receives information from the baseboard management controller (BMC) on the SBC indicating when it is safe to remove the rear panel board. The second LED indicates activity on the IDE interface and/or the CompactFlash expansion card.

The CompactFlash is selectable as a master or slave, using an on-board switch. A floppy drive connector and 4-pin floppy power connector (J8) for external media are available on the internal portion of the board. For cable information, please see “Accessories” in the ordering information section.

Switch Options

The RTM4808 features two push-button switches on the face plate - one to reset the host SBC and one to issue a non-maskable interrupt (NMI). A hot-swap ejector switch is incorporated into the lower ejector mechanism to notify the SBC of the necessity to shut down, should the RTM4808 need to be removed.
