Jumpers

The jumpers present on the mainboard are used by the manufacturer
only; there are no jumpers used to configure the operation of the
mainboard.

CMOS Clear

JPT1 is used to clear CMOS and will also clear any passwords. JPT1
consists of two contact pads (#11 in Figure 3-135).

Clearing CMOS

1. First power down the blade and remove it from the enclosure.
2. Remove the blade cover to access the mainboard (see Section :

Removing/Replacing the Blade Cover on page 93 for further
details). Short the CMOS pads with a metal object such as a small
screwdriver.

3. Replace the cover, install the blade back into the enclosure and

power it on.
