Disable - Disabling a port is the same as manually partitioning it,
except that you must also manually reconnect it. For example,
to prevent a certain device from accessing the network or to
reduce network traffic you may opt to disable the port. No
incoming packet transmission can occur on a disabled port.
Ports can be disabled/enabled using the on-board configuration
program or via optional network management software. They
can also be enabled by restarting the system, which restores the
factory default settings.
FThe Partition/Disable LEDs are also used as diagnostic LEDs.
Please refer to

Port Status Indicators
There are 12 pairs of port status indicators. Each pair consists
of a Link/Activity LED (in the top row) and Partition/Disable
LED (in the bottom row). The last pair displays status for both
the 12MDI-X and 12MDI port, either of which is currently in
use. Also note that port status for the memory extender
modules is displayed directly on the module as described in the
section on SmartExtender Module Indicator earlier in this chapter.
