to the individual User's Guides for specific frame and carrier information.]

The DX1/200-SW160/RH Hot Swap/Repeater Isolator Board (Figure 1) is an upgrade attachment

for the DE100i-SW160 and DE200i-SW160 receiving frame, while the DX1/200-SWC160/RH

is an upgrade attachment for the DE100i-SWC160, DE200i-SWC160, S20A102, and S20A108

receiving frame. This attachment provides a bus-isolating hot swap feature as described

below.

Bus-Isolating Hot Swap Function

The Ultra160 DX1/200 boards allow installation, removal or exchange of Ultra160 DE100 and

DE200 carriers while the computer system is operating by monitoring and protecting the

computer system and other peripheral devices on the SCSI bus. The isolator board eliminates

the need to shut down the system when adding or removing a SCSI device by performing two

functions:

1. Delays power up/down of the drive until the time period between SCSI bus cycles.

This prevents the interruption of any SCSI bus activity being done by other devices

on the bus.

2. Prevents drive power sequencing from generating noise on the SCSI bus, thus

preventing data transfer corruption on other devices.

Please note that, whereas UNIX and Apple-based systems provide mount/dismount drive

commands, most PC systems do not provide such a feature. When using one of these operating

systems, it may be necessary to reboot the computer after adding or changing a drive. This

reboot activity will force the SCSI host adapter to re-scan its SCSI bus for physically attached

drives, and will then be able to access the new or changed drive.

Attaching the Isolator Board

The DE100i-SW160, DE100i-SWC160, DE200i-SW160, DE200i-SWC160, S20A102, and

S20A108 may be purchased with the isolator board factory-installed. If the board has not

already been attached to the Data Express receiving frame, follow the instructions below to

add the board. Otherwise, proceed to the section "Using the Isolator Board" for usage

instructions.
