Jumpers
Any 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
JBT1 is used to clear CMOS and will also clear any passwords. JBT1 consists of two
contact pads located near the BIOS chip.
Clearing CMOS
1. First power down the blade and remove it from the enclosure.
2. Short the CMOS pads with a metal object such as a small screwdriver.
3. Install the blade back into the enclosure and power it on.
