AC power socket (recommended)
You are recommended to use a three-terminal single-phase power socket with ground contact, which
must be grounded reliably. Normally, the ground contact of the power supply system in a building was
buried during construction and cabling. Still, before connecting the AC-input power cord, you must make
sure that the power supply of the building is well grounded.
Connecting the AC-input power cord
Step1 Make sure that the PGND is securely connected to the earth ground.
Step2 When the power switch of the router is in the OFF position, insert one end of the power cord
accompanying the router into the power socket on the chassis rear panel, and connect the other end of
the cable to an AC power source at your installation site.
Step3 Place the power switch of the router to the ON position.
Step4 Check that the PWR LED on the front panel of the router is on for correct connection.
Connecting the Console Terminal
Console port
MSR 20 provides an RS232 asynchronous serial console (CON) port for router configuration, through
which you can complete the configuration of the router. For its attributes, refer to
Table 14 :
Table 14 Attributes of the console port
Attribute Description
Connector RJ-45
Interface standard RS232
Baud rate 9600 bps (default) to 115,200 bps

Console cable
Console cable is an eight-wire shielded cable. At one end of the cable is a crimped RJ-45 connector to
the console port on the router; at the other end of the cable is a DB-9 (female) connector to the serial port
on the console terminal.
