Accton Technology 12i, 12mi SNMP manual Function Indicates port link and activity

Fast EtherHub 3500 System User’s Guide

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.

ΦThe Partition/Disable LEDs are also used as diagnostic LEDs. Please refer to Diagnostic Test Indicators for more information.

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.
