CHAPTER 5: Troubleshooting
5. Troubleshooting
If you encounter a problem when you install or operate the SCSI Switch II,
please review this section for likely causes and what to do if you eliminate
these possibilities but the problem remains.
5.1 Common Problems
Problem 1. LEDs are not lit:
Check whether the power supply is the one supplied with the SCSI Switch II.
You can use a different power supply, but it must have a rating of 9 or 12 volts
DC, 1 amp maximum with the positive terminal on the inside of the
connector. Also, check whether the power supply is connected to a live power
outlet.
Problem 2. Branch-indicator LED flashes constantly:
This is an indication that the main bus and the formerly selected branch bus
(the branch corresponding to the number on the front-panel display) are
busy with data traffic, but a different branch has been selected (button has
been pushed to a new setting). This condition will resolve itself when, after
traffic stops for at least eight seconds, the Switch disconnects the formerly
selected branch bus and connects the new branch.
