HyperWire Card Hardware Manual
Chapter 1: HyperWire™ Card
1.2. HyperWire Card Firmware
Two firmware images are embedded on the HyperWire card, a
Default
image and a
Recovery
image. The
default image is updated each time you update the firmware. The recovery image is the image of the original
firmware that was installed at the factory. The position of the JP1 jumper determines the active firmware
image on the HyperWire card (
). JP1 should remain in the default [1-2] position under most
circumstances. The recovery mode should only be used if you think that the default firmware image has
become corrupt.

Firmware updates will overwrite this image.
Recovery

Use this image to reload the default image. The default image could
become corrupt if, for example, power is interrupted during a firmware
update.
If you suspect that the default image has become corrupt, use the status LED DS1 on the HyperWire card
(
) to determine if the HyperWire card is initialized. The LED should come on and remain illuminated
immediately after you turn on the PC. The LED can also flash briefly during a PC restart. If the
LED continues to flash or remains off, the default firmware image could be corrupt.
