What does jumper j1h3 do - Computers & Internet

Remove the jumper plug from the CMOS jumper (CLEAR CMOS) pins 2 and 3. Place the jumper plug on the CMOS jumper (CLEAR CMOS) pins 1 and 2 and wait approximately five seconds. Remove the jumper plug and replace it on the CMOS jumper (CLEAR CMOS) pins 2 and 3

CS = Cable Select
DS = Master
SP = Spare (Slave)

There is the Password jumper (PSWD), and the CMOS jumper.

The CMOS battery is also termed the RTC battery.
Real Time Clock battery.
The CMOS jumper is labeled as RTCRST.

Real Time Clock ReSeT.

Jumper pin location is confusing if you go with Dell documentation.

http://support.dell.com/support/edocs/systems/op330/en/ug/mtparts.htm#wp1607303

Dell Support documentation shows the RTCRST jumper pins near the Intel chipset, and PSWD jumper pins near the outside edge of the motherboard.

I'm also looking at the Dell Optiplex 330, Technical Guidebook, Inside the Optiplex 330,

http://www.dell.com/downloads/global/products/optix/en/optix_330_techspecs.pdf

Location of RTCRST jumper pins, is near the left corner of the Intel chipset, instead of the right as shown above, and PSWD jumper pins are in the same location.

And several views of Optiplex 330 motherboard's on Ebay,

(Nice to have that Zoom in feature on Ebay now)

Jumper pins close to the white SATA 2 connector, are the RTCRST jumper pins.

Jumper pins at the bottom side of the Intel chipset are the PSWD jumper pins.

Jumper cap stays on PSWD jumper pins.
No jumper cap on the RTCRST jumper pins.

Almost all motherboards contain a jumper that can clear all CMOS settings along with the BIOS password. The location of this jumper varies depending upon the motherboard brand. You should read your motherboard manual to check its location. If you don't have the manual then look for the jumpers near the CMOS battery. Most of the manufacturer label the jumper as CLR, CLEAR, CLEAR CMOS, etc.

When you find the jumper, look carefully. There will be 3 pins and the jumper will be joining the center pin to either left or right pin. What you need to do, is remove the jumper and join the center pin to the opposite pin. e.g. if the jumper joins center pin to left pin, then remove it and join center pin to right pin. Now wait for a few seconds and then again remove the jumper and join the center pin to left pin.

Make sure to turn the PC off before opening the cabinet and resetting the jumper

Hope this helps

That depends upon the IDE cable you are attaching the CD ROM to.
There are two IDE cables attached to the motherboard, on IDE 1 connector/cable will be your boot hard drive (C drive) and this will be jumpered to Master and you can attach the CD ROM drive to this cable and set the jumper on the CD drive as Slave.
On IDE 2 connector/cable if there are no drives attached to this cable then the CD ROM drive can be jumpered as Master or Slave..
If there is another drive on the same IDE 2 cable then look at the jumper on that drive, if it is jumpered to Master then the CD drive needs to be jumpered to Slave. If the existing drive is jumpered as Slave then the CD drive needs to be jumpered as Master.
Both drives on the same IDE cable cannot be jumpered with the same setting.

Maxtor jumper as follow:
looking at the connector top row 5 pins, buttom row 4 pins.
the single pin on the top row is index pin.
master jumper is located between top 2nd pin and 1st buttom, counting from the left.
slave has no jumper on any of the pins.
cable select jumper is located between top 4th and buttom 3rd pin. counting from the left.

slave is NO jumpers at all


(Master) - The vertical jumper over the J50 pins is configuring the drive as a Master. The horizontal jumper over the J48 and J46 pins is in the Storage position.
(Master with CLJ) - The vertical jumper over the J50 pins is configuring the drive as a Master. The vertical jumper over the J46 pins is in the Cylinder Limitation position (CLJ).
(Slave) - No jumper is required to configure the drive as a Slave. The jumpers over the J48, J46, J44 and J42 positions are both in the storage position.
(Slave with CLJ) - The jumper over the J44 and J42 positions is in the storage position. The jumper over the J46 pins is in the Cylinder Limitation position (CLJ).
(Cable Select) - The jumper over the J48 position is configuring the drive for Cable Select. The jumper over the J44 and J42 pins is in the storage position.
(Cable Select with CLJ) - The jumper over the J48 position is configuring the drive for Cable Select. The jumper over the J46 pins is in the Cylinder Limitation position (CLJ).

Clear CMOS jumper Jumpers to enable system wake up on keyboard or USB devices PS/2 keyboard power jumper Fan power jumper Jumpers to enable/disable SMBus 2.0 support This is the jumpers which is avalable for the motherboard.
If there is no jumper for your oparation It will detected the changes Automatically.
