Re: K260 disk jumper setting

hi jannik,

its relativly easy really, there will be some pins/jumpers on the mech somewhere which work in binary.
just add 1 or 2 jumpers here in the correct sequence like this
they work 4-2-1
so for id 6 you put a jumper on pins 4 and 2
so for id 3 you put a jumper on pins 2 and 1
so for id 1 you just put one jumper on pin 1
there is usually a small diagram on the mech denoting which the 3 pins are you need to use. aswell on which pins are for term power delay start and other features depending upon mech.

you need to avoid id 7 which is reserved for the controller id in the K class and dont use the ids already used.

Re: K260 disk jumper setting

Hi jannik,

The disks of k260 are not hot swap, to set the scsi id on the 2 new disks, you have to pull out the cage of disks, and look at the jumpers put on each disk ( the jumpers decide which scsi id). If the id of 1st disk is 1, the 2nd is 2, put id 3 and 4 for the 2 new disks.

Re: K260 disk jumper setting

in other words should the setting be:
if this is how the jumpers look:
* * *
* * *
4 2 1

1. disk id 1
* * x
* * x
4 2 1
2. disk id 2
* x *
* x *
4 2 1
3. disk id 3
* x x
* x x
4 2 1
4. disk id 4
x * *
x * *
4 2 1

What if there is a CD-ROM as well on the system what SCSI id would it have.

I will wait with the point until i have added the disks.

Re: K260 disk jumper setting

Hi ,

the cage containing the disks is divided into 2 parts, one for disks and one for cd/dvd rom and tape.
The scsi id of cd rom won't affect here cause, they are on 2 different paths, on PDC : type sea.
you will have something like this:

10/0.3
10/0.4
10/12/5.3

Re: K260 disk jumper setting

hi jannik,

stop there before you install the disks

your 2 disks are at ID 6 and ID5 and the next two should be ID4 and ID3.

BUT...

The new disks you have are SE scsi disks with a 50pin scsi connector

The standard disks in the K class are fast wide differential drives and have a 68pin connector.

Not just the difference in pins as you can get 50-68pin adapters. These are a different standard and could blow the scsi bus on the system or damage the drive. these are nopt compatible in the K series

You need A3353A 4.5gb drives for the K class
