About this Guide

This user guide provides instructions to manage, control and monitor the switch using
the Simple Network Manager.

This guide is intended for operating personnel (sometimes called craft persons). Users
must be familiar with the basic operations of a Layer 2 switch. Access to the hardware
interface is by a computer with a telnet terminal.

About the Simple Network Manager

The Simple Network Manager provides you with a simple and intuitive tool to manage,
control and monitor the switch. Most operations can be performed with a click of the
mouse. The Simple Network Manager also includes a command line interface for
managing the switch.

The Simple Network Manager is divided into four main pages, arranged in order of the
frequency that you will typically access them:

System

Provides a real-time overview of the system, and allows you to control downlink
ports and view detailed log activities. See "About the System Page" on page 3.

Ethernet

Provides switch configuration and management as well as uplink and downlink port
management. See "About the Ethernet Page" on page 4.

VLAN

Allows users to view, establish and assign VLANs. See "About the VLAN Page" on
page 20.

Displaying the current installed version

When performing an incremental upgrade, you will need to know the current installed
version of firmware on the unit so the next upgrade can be installed. When applying
incremental upgrades, all upgrades must be done in order and no upgrades can be
skipped.

Example usage:

# pal-version

Most issues can be identified from the initial System > Overview page.

• Monitor the switch Temperature in the System Overview panel. To see

temperature pattern and threshold, go to the Performance tab.

• The shading of the BNC port number in the Ethernet Ports table indicates any

network issues; see Viewing port status on page 6.

• If the port number is in red text and there is a high number in the Link Down

field, there are likely physical errors with the port and/or cable.

• To further investigate a high Link Down number, double-click on the number to

view link transition statistics for the port. This historical information can help you
to identify patterns of downtime (e.g. frequency, consistent time, duration, etc.).

• Hover over a BNC port number to see the number of packets received and

transmitted. For a breakdown of these, go to the Ethernet > Downlink Ports page
and hover over the Total number.
