AT-3714F and AT-3726 Installation Guide

How the Switch Reports Problems
The switch detects and processes errors as follows:
❑ The LEDs indicate problems with the port and power.
Table 3-1 describes the switch LEDs.
❑ In a TCP/IP environment, if you have configured the software
correctly, the management software triggers an SNMP trap
message. As a result, the software then sends traps to alert the
network manager when a trigger occurs. This type of software
configuring allows the network administrator/manager to
pro-actively monitor their network.
Table 3-1 lists and describes the switch LEDs.
