2.2.5 10/100Base-T LAN Connectors (CN2 & CN5)
CN5 is a standard RJ-45 connector for Ethernet connection. A box
header (CN2) is also available for internal connection.
The chassis carrier board comes with a special cable (P/N 1703120900).
This cable has a box header at one end and an RJ-45 at the other end. An
adaptor bracket allows users to fix the RJ-45 at chassis by using an exist-
ing DB-9 COM port opening.
2.2.6 Temperature Sensor Connectors (CN4 & CN7)
These connectors interface with LM75 digital temperature sensors
through SM bus. Up to 9 temperatures can be monitored by SNMP-1000-
B1. One sensor located on the kernel module is designated as Temp. 0,
and up to 8 external sensors can be connected. The external temperature
sensor and cable are available from Advantech. Sensors can be con-
nected in series in any order to either connectors, but each sensor has to
be set to a unique ID ranging 1 ~ 8 by setting the DIP switch located at
the sensor board.
