Ultra160 I/O Repeater Module
CAUTION: When using the double-stacked VHDCI connectors (Port A-1 & A-2)
simultaneously, offset VHDCI cable connectors must be used for proper
fit. Failure to use proper cables may result in damage to the I/O repeater
module VHDCI connectors!
VHDCI connectors are easily damaged by improper handling. Visually
inspect each connector for bent contacts and carefully align prior to
insertion.
NOTES: The InfoStation 9-bay supports daisy-chaining for Ultra160 applications
only.
Port-A1 and Port-A2 are connected internally.
Port-A requires an external terminator if:
1. It is connected to the end of an external SCSI cable.
2. It is "open" and not in use. In this case, only Port B is used.
Port-B does not require a terminator (it is terminated internally).
I/O Repeater Module LEDs
Error LED (Amber) - Flashing indicates a detection in either:
1. Over temperature
2. Low termination voltage
3. Invalid differential voltage
Activity LED (Green) - ON indicates that activity is present.
OFF indicates that there is no activity present.
Refer to the UIM or InfoMon for detailed information on I/O repeater module status.
