Step 4 Install the PERC 4 Controller
Select a 3.3V PCI slot and align the controller PCI bus connector to the slot. Press down gently but firmly to make sure that the controller is properly seated in the slot, as shown in Figure 3-3. Screw the bracket to the system chassis.
Figure 3-3. Inserting the PERC 4 Controller into a PCI Slot
Step 5 Connect SCSI Cables and SCSI Devices
Connect the SCSI cables to the SCSI connectors and SCSI devices.
Connect SCSI Devices
Perform the following steps to connect SCSI devices.
- Disable termination on any SCSI device that does not sit at the end of the SCSI bus.
- Configure all SCSI devices to supply TermPWR.
- Set proper target IDs (TIDs) for all SCSI devices.
The host controller has a SCSI ID of 7.
- Connect the cable to the devices.
The maximum cable length for Fast SCSI (10 MB/s) devices or single ended (SE) is 3 meters. For Ultra SCSI devices, it is 1.5 meters. The cable length can be up to 12 meters for LVD devices.
Cable Suggestions
System throughput problems can occur if SCSI cable are not the correct. You should:
- Use cables up to 12 meters for Ultra3, Ultra160, and Ultra320 devices.
- For single-ended SCSI devices, use the shortest SCSI cables (no more than 3 meters for Fast SCSI, no more than 1.5 meters for an 8-drive Ultra SCSI system and no more than 3 meters for a 6-drive Ultra SCSI system).
- Use active termination.
- Avoid clustering the cable nodes.
- Note that cable stub length should be no more than 0.1 meter (4 inches).
- Route SCSI cables carefully.
- Use high impedance cables.
- Do not mix cable types (choose either flat or rounded and shielded or non-shielded).
- Note that ribbon cables have fairly good cross-talk rejection characteristics.
Step 6 Set Target IDs
Set target identifiers (TIDs) on the SCSI devices. Each device in a channel must have a unique TID. Non-disk devices should have unique SCSI IDs regardless of the channel where they are connected. See the documentation for each SCSI device to set the TIDs. The PERC 4 controller automatically occupies TID 7 which is the highest priority. The arbitration priority for a SCSI device depends on its TID. Table 3-3 lists the target IDs.
Priority | Highest Lowest | |||||||||||
TID | 7 | 6 | 5 | ... | 2 | 1 | 0 | 15 | 14 | ... | 9 | 8 |
Step 7 Set SCSI Termination
The SCSI bus is an electrical transmission line and must be terminated properly to minimize reflections and losses. Termination should be set at each end of the SCSI cable(s).
For a disk array, set SCSI bus termination so that removing or adding a SCSI device does not disturb termination. An easy way to do this is to connect the controller to one end of the SCSI cable and to connect an external terminator module at the other end of the cable. The connectors between the two ends can connect SCSI devices. Disable termination on the SCSI devices. See the manual for each SCSI device to disable termination.
Set the termination so that SCSI termination and TermPWR are intact when any hard drive is removed from a SCSI channel, as shown in Figure 3-4.
Figure 3-4. Terminating Internal SCSI Disk Array
Step 8 Start the System
Replace the system cover and reconnect the AC power cords. Turn power on to the host system. Set up the power supplies so that the SCSI devices are powered up at the same time as or before the host system. If the system is powered up before a SCSI device, the device might not be recognized.
During boot, the PERC 4 BIOS message appears:
PowerEdge Expandable RAID Controller BIOS Version x.xx date
Copyright (c) Dell Computer Corporation
Firmware Initializing... [ Scanning SCSI Device ...(etc.)... ]
The firmware takes several seconds to initialize. During this time the adapter scans the SCSI channel. When ready, the following appears:

Or press <Ctrl><H> to run WebBIOS
The PERC 4 BIOS Configuration Utility prompt times out after several seconds.
The PERC 4 host controller number, firmware version, and cache SDRAM size display in the second portion of the BIOS message. The numbering of the controllers follows the PCI slot scanning order used by the host motherboard.
Light-emitting Diode (LED) Description
Perc Scsi & Raid Devices Driver Download For Windows 8.1
When you start the system, the boot block and firmware perform a number of steps that load the operating system and allow the computer to function properly. The boot block contains the operating system loader and other basic information needed during startup.
As the system boots, the LEDs indicate the status of the boot block and firmware initialization and whether the system performed the steps correctly. If there is an error during startup, you can use the LED display to identify it.
Table 3-4 displays the LEDs and execution states for the boot block. Table 3-5 displays the LEDs and execution states during firmware initialization. The LEDs display in hexadecimal format so that you can determine the number and the corresponding execution state from the LEDs that display.
LED | Execution State |
|---|---|
0x01 | Setup 8-bit Bus for access to Flash and 8 Bit devices successful |
0x03 | Serial port initialization successful |
0x04 | Spd (cache memory) read successful |
0x05 | SDRAM refresh initialization sequence successful |
0x07 | Start ECC initialization and memory scrub |
0x08 | End ECC initialization and memory scrub |
0x10 | SCRAM is present and properly configured. About to program ATU. |
0x11 | CRC check on the firmware image successful. Continue to load firmware. |
0x12 | Initialization of SCSI chips successful. |
0x13 | BIOS protocols ports initialized. About to load firmware. |
0x17 | Firmware is either corrupt or BIOS disabled. Firmware was not loaded. |

Step 9 Run the PERC 4 BIOS Configuration Utility, WebBIOS Utility, or Dell Manager
Press <Ctrl><M> when prompted during the boot process to run the BIOS Configuration Utility or <Ctrl><H> to run the WebBIOS Configuration Utility. You can also run Dell Manager in Novell NetWare and Red Hat Linux to perform the same functions, such as configuring arrays and logical drives.
