Local Channel Bypass
Bypass is used to remove the unit from the local channel without interrupting the
channel communication link to other units/hosts. The Bypass function allows local
troubleshooting of the network unit without interfering with the local channel
communication link.
Use the following procedure to set Bypass.
1. Place the unit offline (for each channel if a 2-channel configuration) by pressing
the Shift key, followed by the Enter key, followed by the channel number (1 or 2).
2. Wait for the offline messages and indicators to light confirming an offline condition.
Refer to Chapter 3, “Operation.”
Note: Powering off the unit while either offline LED is not on may result in host
system problems.
