Troubleshooting

Problem: The controller does not respond and one of the following LED patterns

occurs at power-up:

LEDs 6 and 7 alternating with LEDs 5 and 8

LEDs 5 and 6 alternating with LEDs 7 and 8

LEDs 5 and 7 alternating with LEDs 6 and 8

Solution: These patterns indicate that the DPT controller is not being configured by

the motherboard BIOS. SmartRAID V Century controllers require a

motherboard BIOS that supports multifunction devices, where one of the

devices is a PCI-PCI bridge. All SmartRAID V controllers require a BIOS

that supports large memory-mapped address ranges.

Refer to the SmartRAID V READ.ME file on the DPT diskette for

information about motherboard compatibility and a list of motherboards

that DPT has tested with SmartRAID V products.

Problem: The controller does not respond and one of the following patterns of LEDs

flash once per second at power-up:

PATTERN MEANING

7, 6, 5, 2, 1 None

7, 6, 5, 3, 1 High

7, 6, 5, 3, 2 Mismatch

7, 6, 5, 3, 2, 1 Invalid

Solution: These patterns indicate that there is a problem with the memory modules

on the controller.

None: Either no memory modules were detected on the controller,

or there is no module in socket 1. Socket 1 must always have

a 16MB or 64MB 60ns EDO memory module installed.

High: Too much memory has been detected on a Decade or

Century controller. Remove memory so that the total is less

than or equal to 64MB.

Mismatch: Memory modules of mixed sizes have been detected or a

SIMM slot was skipped. All installed modules must be the

same size and must be filled sequentially from socket 1 to

socket 4.

Invalid: A memory module of a size other than 16MB or 64MB has

been detected. Use only 16MB or 64MB memory modules.

NOTE: Do not install non-EDO SIMMs or DIMMs. This will cause data

corruption.
