Front Panel Description
The front panel, shown in Figure 1-2, contains four groups of LEDs that provide the status of the
Ethernet connection, 56K DSU port, WAN port, and general status of the ProxyServer. The Ethernet
LEDs indicate the status of LAN activity. The 56K DSU LEDs indicate the status of the internal DSU
port (WAN 1). The WAN Link LEDs indicate the status of the external Data Communications
Equipment (DCE) device connected to WAN 2. There are also two LEDs which indicate whether the
self test passed or failed (Fail) and if the power On/Off switch on the back of the ProxyServer is
turned On (Power).
