I-Button
An onboard I-Button, located next to
USB Ports 2~3, is a 1-wire computer
chip enclosed in a durable stainless
steel cylinder. The I-Button stores in-
structions, provides electronic interface
and allows HostRAID to operate with
Mega-RAID fi rmware.
5-10 Jumper Settings
To modify the operation of the
serverboard, jumpers can be used
to choose between optional settings.
Jumpers create shorts between two
pins to change the function of the
connector.
Pin 1 is identifi ed with
a square solder pad on the printed
circuit board. See the serverboard
layout pages for jumper locations.
Note: On a two-pin jumper, "Closed"
means the jumper is on both pins and
"Open" means the jumper is either on
only one pin or completely removed.
CMOS Clear
JBT1 is used to clear CMOS (which will also clear any passwords). Instead of pins,
this jumper consists of contact pads to prevent accidentally clearing the contents
of CMOS.
To Clear CMOS
1.
First power down the system and unplug the power cord(s).
2.
With the power disconnected, short the CMOS pads with a metal object such
as a small screwdriver.
3.
Remove the screwdriver (or shorting device).
4.
Reconnect the power cord(s) and power on the system.
Note: Do not use the PW_ON connector to clear CMOS.
