Installing Antennas; Connecting The Console Terminal - H3C MSR 20-1X Installation Manual

Recommended AC power connector
A three-terminal, single-phase power connector with a grounding contact is recommended. Normally,
the grounding contact of the power supply system in a building was buried during construction and
cabling. Before connecting the AC power cord, you must make sure that the power supply of the building
has been well grounded.
Connecting the AC power cord
Make sure that the PGND is securely connected to the ground.
Step1
Move the power switch of the router to the OFF position, and connect one end of the power cord shipped
Step2
with the router to the power socket on the rear panel, and the other end to an AC power source.
Move the power switch to the ON position.
Step3
Check whether the power LED on the front panel of the router is ON. If the power LED is ON, the power
Step4
cord is properly connected.

Installing Antennas

Fasten the attached antennas onto the router. Avoid over-tightening. Once the network is up and running,
you may need to adjust the antennas to achieve better coverage. Usually, the antennas should be vertical
to the ground or ceiling to achieve the optimal coverage, as shown in the following figure.

CAUTION:
Do not touch the antenna top, especially after the antenna is connected with the grounding contact.
Otherwise electrostatic discharge (ESD) may damage the router.

Connecting the Console Terminal

Console interface
MSR 20- 1 X routers each provide an RS232 asynchronous serial console (CON) interface for router
configuration.
