Check for link beat detection on the port. When the switch first detects the link beat signal (also called “link test pulse signal”) coming from an active device, the port LED comes ON for approximately 3 seconds.

This is a network layer test that you can run on Novell NetWare IPX networks. The switch sends IPX test packets to a specified network device. This works with devices that have an IPX address and are able to respond to an IPX test packet. Most end nodes using IPX will respond to this packet. You specify the remote device by its IPX address.

There are two levels of reset: ■ Hardware reset: Momentarily interrupts switch operation, performs a complete hardware self test, clears the switch event log, and reboots the switch.

To clear the password, follow these steps: 1. Verify the switch has powered-up, and passed self test. 1. Press the Clear button on the Management Module for at least one second. Press the Clear button for at least one second.

These features are useful for acquiring periodic switch software upgrades and for storing or retrieving a switch configuration. File Transfers Downloading an Operating System There are several methods you can use to download new operating system code to the Switch Management Module.

In networks where there is more than one physical path between any two nodes, STP ensures a single active path between them by blocking all redundant paths.
