[. . . ] A trap file consists of several messages. Refresh ­ updates the information from the SNMP. Clear ­ erases all messages in the trap file. Set ­ saves last updates of parameters. Exit ­ terminates the current screen (tab). Graph ­ provides a graphical representation of selected power parameters. 4. 4. 3 Port Level The PoL ports are located on the top row of the selected device panel. The bottom row in the panel is used to carry data. Individual ports can be activated or disabled, by pointing and double-clicking on the graphical representation of that port(s). By doing so, a pop-up menu appears on the window. When the port is enabled, the indication is in yellow; with the port disabled, the representation is in black. 4. 4. 4 Visual Indications The graphical display panel includes a number of visual indicators for operating power input and output ports. 4. 4. 4. 1 Power indications Two LEDs on the front panel, marked by "AC" and "DC", provide the Power over LAN Midspan power status. When either one of the indicators is illuminated in green, the Power over LAN Midspan is receiving AC or DC power. The "AC" and "DC" indicators are lit in orange to indicate an internal fault. Refer to Table 4-1 for additional information. Version 2. 1 25 March 2003 SNMP 4. 4. 4. 2 Port status One bi-color indicator (green and orange), per port, provides port status: !Green indicates that the terminal unit has been identified as "Power over LAN Enabled" and is active and receiving power. Orange indicates that the port is not supplying power and is not active. Refer to Table 4-1 for additional information. Note Due to the standard detection process performed on each PoL port, power will not be supplied to an Ethernet device, that is not PoL-enabled (indicated in orange or off). In this way, Ethernet devices (not PoL-enabled) will not be affected by this connection.

Power over LAN Solutions 50 Catalog Number: 06-6910-056 WEB Manager User Guide Appendix A- Useful Information 7 Useful Information The Simple Network Management Protocol (SNMP) is a standard that allows management data on different network devices to be read and monitored, as well as controlled by an application. PowerDsine PowerView monitors and controls SNMP objects on any device implementing an SNMP agent. 7. 1 SNMP Background 7. 2 SNMP Protocol SNMP is based on the manager/agent model. SNMP is referred to as "simple" because the agent requires minimal software. Most of the processing power and the data storage resides on the management system, while a complementary subset of those functions resides in the managed system. [. . . ]
