1. If you | plan to | install both internal and | external SCSI devices, | you | |
the instructions given in “Installing or Removing Internal Drives” on | pa | ||||
addition | to the instructions in this section. Read “Installing or Remo | ||||
Internal | Drives,” | and | then return here. |

2. Do not exceed the following cable lengths:
Ÿ If | you connect | one | or more Fast SCSI devices to | the | SCSI | control |
total | length of | all | cables (internal and external) | must | not | exceed |
(9.8 | feet). |
|
|
|
|
|
ŸIf you do not connect Fast SCSI devices to the SCSI controller,
length of all cables must not exceed 6 meters (19.7 feet).
You | must | set | a |
| unique | SCSI | ID for | each | external | SCSI | device | so | that | |||||||||||
can | identify | the | devices. The | controller | can then |
| ensure | that | differe | |||||||||||||||
not | attempt | to | transfer | data | at the same time. Therefore, do not set | |||||||||||||||||||
for | external | devices | to | the | values | you | used | for | the | controller. |
|
| ||||||||||||
If | you | plan | to | attach | an | external | SCSI | device, | you might need to ord | |||||||||||||||
SCSI | cable. To | use an | external | device | with | the | Netfinity | 5000 | server, | y | ||||||||||||||
connect it | to | the external SCSI connector, using a |
| SCSI | cable. This | SCSI | ||||||||||||||||||
must | have |
| the | proper | connector | for the SCSI external connector on one |
| |||||||||||||||||
the proper connector for the | external | device | on | the | other | end. If | a | |||||||||||||||||
does | not | come |
| with the external device, or if | it is the wrong type, | |||||||||||||||||||
order | one. To | select and order the correct SCSI cable for use with |
| |||||||||||||||||||||
device, | contact | your | IBM | reseller | or | IBM | marketing | representative. |
