*DIP switches also can be managed via console commands or with the Metrobility NetBeacon® or WebBeacon™
management software. Refer to the
Command Line Interface Reference Guide, NetBeacon Element Management
Software Installation & User’s Guide or WebBeacon Management Software Installation & User’s Guide for software
management information.
When setting DIP switches * on SW2, the OPEN position is when the
lever of the switch is pushed up toward the word “OPEN.” The
CLOSED position is when the lever is pushed down toward the board.
On the rocker DIP switch (SW1), the OPEN position is when the
“OPEN” side of the switch is down and the numbered side is up. The
CLOSED position is when the numbered side of the switch is down and
the “OPEN” side is up. See illustration below.

Auto-Negotiation Switch (AN1, AN2, AN3, AN4)
Switch ANx controls the use of auto-negotiation on its associated port
(e.g., AN1 sets auto-negotiation on Port 1). To enable auto-negotiation,
the switch must be OPEN. To disable this function, the switch must be
CLOSED. By default, auto-negotiation is enabled.
When auto-negotiation is enabled on a port, it advertises 10/100Mbps
half/full duplex capabilities. When auto-negotiation is disabled, the
port’s duplex is determined by the FD switch setting, and its speed is
set by its corresponding 100Mx switch.
Speed Switch (100M1, 100M2, 100M3, 100M4)
The 100Mx speed switch controls the speed setting on its associated
port (e.g., 100M2 determines the speed on Port 2). If auto-negotiation is
disabled on a Port x, its speed will be set to one of the following:
• 100Mbps if the 100Mx switch is OPEN. (default)
• 10Mbps if the 100Mx switch is CLOSED.
When auto-negotiation is enabled, the 100Mx switch is ignored.
