The SNMP 540 Front Panel display windows provide graphical interface to a selected DSU. To launch a Front Panel, either select the unit you intend to work with in the HPOV Map window, then select Front Panel from the Performance menu for that window; or double click on the unit icon in the map window.

The application responds by displaying a window that depicts the front panel of the selected unit: • SNMP 540 IFP DSU, shown in Figure 4-1

• SNMP 540EN DSU, shown in Figure 4-2

The LEDs shown in a Front Panel display reflect the states of the actual indicators on the physical unit. The complement of indicators displayed for the two models of DSU differ sharply. The SNMP 540 IFP DSU Front Panel display contains the following indicators:

NS – No Signal indicates when lit that the DSU is not receiving a DDS signal SD – Send Data indicates when lit that the DSU is transmitting data

RD – Receive Data indicates when lit that the DSU is receiving data RS – Request To Send indicates when lit that RTS from the DTE is active

CS – Clear To Send indicates when lit that the DSU is outputting CTS to the DTE CO – Carrier On indicates when lit that the DSU is receiving a usable signal from the network

TR – Terminal Ready indicates when lit that Data Terminal Ready from the DTE is active NORM – indicates when lit that the DSU is in operating mode, when Off the DSU is in test mode

TEST/OK – indicates when flashing that errors were detected during a test DBU – indicator not currently supported

SNMP CO – indicates when lit that the DSU is receiving valid IP frames on the management channel

SNMP DATA – indicates when lit that the DSU is receiving a message on the management channel

SNMP RESP – indicates when lit that the DSU is sending a message on the management channel

SNMP TEST – indicates when lit that the DSU is performing a test initiated by an SNMP command

The SNMP 540EN DSU Front Panel display contains the following indicators: ON – indicates when lit that the DSU is connected to power and functioning

LAN sd – LAN Send Data, indicates when lit that the DSU is sending management data on the Local Area Network

LAN rd – LAN Receive Data, indicates when lit that the DSU is receiving management data on the Local Area Network

LAN cln – LAN Collisions, indicates when lit that collisions are occurring on the Local Area Network, slowing the exchange of management data

NETWORK sd – Network Send Data, indicates when lit that the DSU is sending data on the Telco network

NETWORK rd – Network Receive Data, indicates when lit that the DSU is receiving data on the Telco network

NETWORK lnk down – Network Link Down, indicates when lit that the DSU does not have an active connection to the Telco network, when the DSU is in a test mode this indicator displays a two-headed, up/down arrow

DTE sd – DTE Send Data, indicates when lit that the DSU is receiving data from the DTE to transmit

4-4 Operations

DTE rd – DTE Receive Data, indicates when lit that the DSU is passing received data to the DTE

AUX sd – Auxiliary Send Data, indicates when lit that the DSU is sending management data through its back panel Auxiliary port

AUX rd – Auxiliary Receive Data, indicates when lit that the DSU is receiving management data through its back panel Auxiliary port

The application polls the unit to keep the states of the LEDs in the Front Panel display current. The time of the most recent poll appears in the bottom left corner of the Front Panel display. The time is displayed in white when Auto Poll is enabled, and in yellow when it is disabled.

The Select button, in the upper left corner of the Front Panel displays, provides access to menus for the rest of the TEAM 540 application functions. The following table shows the arrangement of the Select button menus. It differs somewhat from the arrangement on the Map window menu bar.

The two Poll selections in the Select button menu determine when the application collects new information from the unit to update the Front Panel window:

• Selecting Demand Poll causes an immediate update of the display.

• Auto Poll enables you to select updates at 15, 30, or 60 second intervals, or to disable automatic polling. If you select Disable, the Front Panel window displays a static snapshot of the LED states as they were at the last poll, either when the window was launched or a subsequent Demand Poll.

Each time the Front Panel display is opened, its initial polling rate is determined by the Front Panel Poll Rate selection of the HPOV map window Misc menu.

The menu selection Exit dismisses the Front Panel window when you click on it.
