2.5 SB421 CONFIGURATION
The SB421 enables you to connect a VGA monitor and a USB keyboard directly to the
SB421 without having an external PC.
In case no graphics is shown, press <Ctrl> + <Alt> + <F1> to reset the connection.
2.5.1 Initial setup
2.5.1.1 Ethernet Connection
The SB421 supports the following Ethernet connections, all auto negotiating
o 2 x 10/100 Mb/s Ethernet LAN connection for the Base Stations
o 1 x 10/100 Mb/s Ethernet WAN/LAN connection for remote operation and multi-node
backbone connection
o 2 x Ethernet type DC 1 second pulse connection for BS421 timing.
The Ethernet connections are LSA-type connections accepting only solid wires with the
dimension 0.4mm
2
to 0.6mm

.
The Ethernet connections are protected by arresting devices.
The Ethernet connections are limited to SELV
The Ethernet WAN connection is connected to an Ethernet switch or directly to the PC /
Network by means of a straight or crossed Ethernet cable.
The Ethernet LAN connection shall solely be connected to the BS421(s) and optionally to a
redundant SB421 and/or IP backbone for multimode operation.
For redundant BSC operation, please see the chapter describing setup and requirements.
2.5.1.2 Turn on the SB421
Turn on the power to the BSC using SW101 on the Interconnection Board
Turn on the power to the BS421(s) using SW111 (TR1) and SW133 (TR2)
If changes in the BIOS are required, press F2 key shortly after applying power (while screen
