Dell PowerEdge 6650

Legacy I/O Card

Legacy I/O Card Overview

The main purpose of the PowerEdge 6650 Legacy I/O card is to provide external connections for the user, such as the mouse, keyboard, and video. The other main purpose of the card is to relieve some space constraints on the PowerEdge 6650 I/O board.

The Legacy I/O card looks similar to a full-length PCI card in shape and interfaces with the I/O board through a 144-pin HDM and a 216-pin HDM connector. The 32-bit and 64-bit PCI/PCI-X buses are brought up through the connectors to the PCI/PCI-X devices on the Legacy I/O card. The other pins on the connector are used for other signals such as the LPC bus, floppy drive signals and ESM signals.

NOTE: If the system has no POST/no Video but the LCD lights, try to reseat the Legacy I/O card as one of the first troubleshooting steps.

Key features of the Legacy I/O card include:

• ATI Rage XL graphics controller with 8MB video memory and VGA CRT connector
• National Semiconductor PC87414 LPC Super I/O (1 serial port, 1 floppy controller, 1 PS/2 mouse port, and 1 PS/2 keyboard port)
• ESM III architecture through the use of the QLogic Zircon Baseboard Management Controller (BMC)
• Two Gigabit NICs (Broadcom 5700/5411) with a dual stacked 10/100/1000 RJ-45 ports
• Adaptec 7892 SCSI controller (single channel U160) with SCSI connector
• Dual USB port
• 32-bit/33MHz PCI 3.3V signaling
• 64-bit/100MHz PCI-X 3.3V signaling
• Two HDM connectors (144-pin and 216-pin w/guide pin) allowing for easy connection to the I/O board

The Legacy I/O card contains logic for I/O functions not on the I/O board. Three major buses are sent to the card from the I/O board:

1. PCI bus: the 32-bit/33MHz compatibility bus for the video controller (ATI Rage XL) and the SCSI controller (Adaptec 7892)
2. PCI-X bus: the 64-bit/100MHz bus for the two embedded Gigabit NICs (Broadcom 5700 MAC/5411 PHY)
3. LPC bus: the replacement for the ISA bus that is based on PCI for the Super I/O (National PC87414) and the QLogic Zircon BMC

Jumpers

Jumper

Setting

Description

	PASSWRD			The password feature is enabled. (Default)
				The password feature is disabled.
	NVRAM_CLR			The configuration settings are retained at system boot. (Default)
				The configuration settings are cleared at next system boot. (If the configuration settings become corrupted to the point where the system will not boot, change the jumper setting to 1–2 and boot the system. Change the jumper setting back to 2–3 before restoring the configuration information.)
	RSVD			Reserved (do not change). (Default)
	FVS			Reserved (do not change). (Default)

Connectors/Ports

The PowerEdge 6600 system board provides the user with several standard system board ports. Remember that these ports are on the Legacy I/O card. These ports include:
