System Memory

System memory has a minimum of 64 MB of 72-bit unbuffered memory.  The system memory capacity can be expanded up to 1 GB by using combinations of 64-, 128-, and/or 256-MB unbuffered or registered SDRAM DIMMs.  Maximum capacity using unbuffered SDRAM DIMMs is 512 MB.  Maximum capacity using registered SDRAM DIMMs is 1 GB. 

NOTE: DIMMs must be rated to run at 100 MHz.

The system board has four, 168-pin DIMM sockets.  The DIMMs do not have to be inserted in pairs.  The socket population guidelines are as follows:

• Populate the DIMM sockets in order from DIMM_A (right) to DIMM_D (left).
• The largest-capacity DIMM should be in socket DIMM_A, with smaller-capacity DIMMs installed in decreasing sized toward socket DIMM_D.
• Unbuffered and registered SDRAM DIMMs cannot be mixed in the system.  Remove any 64- or 128-MB unbuffered DIMMs before installing 256-MB registered DIMMs.
• DIMMs support the ECC feature, which detects memory errors and corrects single-bit memory errors.  The ECC feature is built into the memory controller on the system board.

Figure 6, DIMM Sockets, shows an isolated view of the DIMM sockets on the system board (see the system board illustration).

Figure 6. DIMM Sockets

For more detailed information about DIMM installation guidelines and samples of DIMM configurations, see "Installing System Board Options" in the Installation and Troubleshooting Guide.

For information on removing and replacing DIMMs, refer to DIMM Removal and Installation. 

Advanced Expansion Subsystems

The computer system offers advanced expansion subsystems that can support a mixture of traditional ISA expansion cards, Plug and Play ISA expansion cards, and PCI expansion cards. The RCU (included with the system) provides a means of avoiding resource conflicts that might arise from such an arrangement.  See the User's Guide for information about using the RCU.

After all legacy cards have been configured with the RCU, the system automatically assigns any required memory space, IRQ lines, and DMA channels to any installed Plug and Play ISA expansion cards and PCI expansion cards the next time the system is rebooted. "Using the Resource Configuration Utility," in the User’s Guide describes the RCU and provides instructions for using it to configure the system.

NOTES: Connector ISA6 shares expansion-card slot space with connector PCI6. Therefore, only one card of either type can be installed in this slot. PCI4 has an in-line connector to support a DRAC card (the SVR_MGT connector on the system board).

Video Controller

The video subsystem is built into the system board and consists of an AGP VGA-compatible video subsystem with an ATI RAGE IIC video controller.  The video subsystem contains 2 MB of SGRAM (non-upgradable), allowing resolutions up to 1024 x 768 x 256.

Integrated SCSI Controllers

An integrated AIC-7890 Ultra 2/Wide LVD SCSI-3 controller on the system board supports up to two 1.6-inch and two 1-inch, or up to four 1-inch internal SCSI hard-disk drives in the system's removable drive cage.  Up to three additional SCSI devices can be installed in the 5.25-inch external drive bays.

The AIC-7890 host adapter and the optional AHA-2940U2W host adapter are part of the Adaptec 78xx series of SCSI controllers and use the 78xx series of SCSI device drivers provided by Dell. The Adaptec SCSI BIOS, which is stored in the computer system's flash memory or on the AHA-2940U2W SCSI controller card, links these SCSI device drivers to the AIC-7890 controller chip or the optional AHA-2940U2W SCSI controller card.

If you are using an optional Dell PowerEdge Expandable RAID Controller (PERC SC/2), the corresponding SCSI device drivers are installed at the same time as the SCSI device drivers for the AIC-7890 and AHA-2940U2W host adapters. Refer to your Dell RAID controller documentation for information on installing your SCSI device drivers. The User's Guide provides instructions for configuring the SCSI device drivers for your RAID controllers.

For instructions on installing SCSI hardware devices such as hard-disk drives, tape drives, or CD-ROM drives, refer to "Installing Drives in the External Bays" and "Installing Hard-Disk Drives" in the Installation and Troubleshooting Guide. After the SCSI devices are installed, you may need to install and configure one or more SCSI device drivers so that your SCSI devices can communicate with your operating system.

SCSI Configuration Guidelines

SCSI devices are installed essentially the same way as other devices.  However, their configuration requirements are different. For details on configuring your particular SCSI subsystem, refer to the documentation that came with your SCSI devices and/or your host adapter card. The following subsections offer some general guidelines.

SCSI ID Numbers

Internal SCSI devices attached to the integrated Adaptec 7890 Ultra2/Wide low-voltage differential (LVD) controller through the 68-pin primary SCSI connector on the system board must have a unique SCSI ID number from 0 to 15.

When SCSI devices are shipped from Dell, the default SCSI ID numbers are assigned as follows:

• The integrated 7890 Ultra2/Wide LVD SCSI controller is configured through the computer's BIOS as SCSI ID 7.
• The first internal SCSI hard-disk drive is configured as SCSI ID 0. (The drive used to boot your system should always be configured as SCSI ID 0.)
• A SCSI tape drive attached to the 7890 Ultra2/Wide LVD integrated controller or the 2940U2W controller card is normally configured as SCSI ID 6, but can be configured to any unused SCSI ID.

NOTE: There is no requirement that SCSI ID numbers be assigned sequentially or that devices be attached to the cable in order by ID number.

SCSI devices installed by Dell are configured correctly during the manufacturing process. You do not need to set the SCSI ID for these SCSI devices.

If you attach additional optional SCSI devices, refer to the documentation that came with each device for information about setting the appropriate SCSI ID number.

CAUTION: Dell recommends that you use only SCSI cables purchased from Dell. SCSI cables purchased elsewhere are not guaranteed to work with Dell PowerEdge systems.

Device Termination

SCSI logic requires that termination be enabled for the two devices at opposite ends of the SCSI chain and disabled for all devices in between. However, because both SCSI controllers are self-terminating and because all internal SCSI cables provided by Dell have active termination at the end of the cables, any SCSI devices you install should have termination disabled on the devices.

Furthermore, when attaching external SCSI devices, you should use only external SCSI cables with active termination on the cable. When used with this type of cable, all external SCSI devices also need to have termination disabled on the devices.

See the documentation provided with any optional SCSI device you purchase for information on disabling termination on the device.

SCSI Cables

The 68-pin (internal) SCSI cable in your system connects SCSI devices (normally SCSI hard-disk drives) to the integrated 7890 Ultra2/Wide LVD controller.

• The connector at the end of the cable attaches to the Ultra2/Wide LVD primary SCSI controller connector labeled "SCSI_ULTRA2" on the system board.
• The other connectors on the cable are used for attaching up to four SCSI hard-disk drives in the internal drive bays.  When the integrated SCSI controller is not being used for hard-disk drives, it can be attached to a SCSI tape drive.

Refer to the documentation that came with the external SCSI device for information on how to connect the device, set its SCSI ID, and disable termination.  Refer to the User's Guide for detailed information pertaining to cabling, formatting, and partitioning SCSI devices.

The Dell PowerEdge 1300 provides one 330 W system power supply that operates from an AC power source of 115 VAC at 60 Hz or 230 VAC at 50 Hz.  The system power supply provides the DC operating voltages and currents listed in Table 1, DC  Voltage Ranges.

NOTE: The power supply produces DC voltages only under its loaded condition. Therefore, when you measure these voltages, the DC power connectors must be connected to their corresponding power input connectors on the system board or drives.

Table 1. DC Voltage Ranges

1	Maximum continuous DC output power should not exceed 330 W. Maximum combined load on +5 VDC and +3.3 VDC cannot exceed 230 W.
2	VFP (volts flea power) — sometimes called "standby power."

Pin Assignments for the DC Power Connectors

The power-supply output voltages can be measured at the back (wire side) of the connectors without disconnecting them. Figures  7, 8, and 9 show the wire side of the connectors.

Figure 7. DC Power Connector P1

1	Pin 13 — PSON# should measure between +4 and +5 VDC except when the power button on the front panel is pressed, taking PSON# to its active-low state.
2	Pin 21 — Thermal fan-speed control (TFSC) is a power-supply input signal used to control the power supply fan speed in special applications.
3	Pin 5 — PWRGOOD should measure between +4 and +5 VDC when the power supply is operating to indicate that all power supply output voltages are within the ranges specified in Table 1, DC Voltage Ranges.
