to the port is prevented from logging into the switch or communicating with other
devices attached to switch ports. A blocked port continuously transmits offline signals
(OLS). Click to remove the check mark and unblock the port. If unblocked, a node
attached to the port can communicate with the switch and communicate with other
nodes attached to the switch.
Enable Beaconing
Click this to make the amber LED by the port blink on the actual switch and the amber
indicator blink for the port in the Hardware View. This enables users to locate the unit
where the port is located. When a blinking amber LED indicator displays by a port, an
attention indicator ( ) displays below the port's connector in the Hardware View and
on the port's row in the Port List View.
Port Diagnostics
Click this option to display the Port Diagnostics dialog box. Use this dialog box to run
an internal loopback and external loopback test on the port. The Port Diagnostics
option enables you to run internal and external loopback tests on any port. To use this
option, follow the detailed steps in the hp StorageWorks edge switch 2/16 service
manual (A7284-96002/AA-RS2JA-TE).
Channel Wrap (S/390 mode only)
Click this while in S/390 mode to display a check mark and allow a channel wrap test
to be initiated from an attached host or device. In this test, frames are sent to the
switch port, then the switch echoes the frames back to the sending device to test the
channel. The switch remains in channel wrap mode until the option is disables. While
in channel wrap mode, the port can only accept echo commands from the host and will
appear to be blocked to all other communication. Click the check box to remove the
check mark and disable channel wrap.
Swap Ports (S/390 mode only)
