Touch only the edges, instead of electronic components when you observe or move a removed
interface module.
To attach an ESD wrist strap:
1.
Wear the wrist strap on your wrist.
2.
Lock the wrist strap tight around your wrist to keep good contact with the skin.
3.
Insert the ESD plug into the ESD socket on the chassis.

EMI

All electromagnetic interference (EMI) sources, from outside or inside of the router and application system,
adversely affect the router in the following ways:
A conduction pattern of capacitance coupling.
Inductance coupling.
Electromagnetic wave radiation.
Common impedance (including the grounding system) coupling.
To prevent EMI, perform the following tasks:
If AC power is used, use a single-phase three-wire power receptacle with protection earth (PE) to
filter interference from the power grid.
Keep the router far away from radio transmitting stations, radar stations, and high-frequency
devices.
Use electromagnetic shielding, for example, shielded interface cables, when necessary.

Lightning protection

To better protect the MSR1000 router from lightning, perform the following tasks:
Make sure the grounding cable of the chassis is reliably grounded.
Make sure the grounding terminal of the AC power receptacle is reliably grounded.
Install a lightning arrester at the input end of the power supply to enhance the lightning protection
capability of the power supply.
Install a special lightning arrester at the input end of outdoor signal lines (for example, E1/T1 line)
to which interface modules of the router are connected to enhance the lightning protection
capability.

Rack-mounting

Before mounting the router in a rack, make sure the following requirements are met:
The rack has a good ventilation system.
The rack is sturdy enough to support the router and its accessories.
The rack has enough space to accommodate the router.
The front and rear of the rack are at least 0.8 m (2.62 ft) away from walls or other devices. Leave
enough clearance on both sides of the rack.
The height of the equipment room is no less than 3 m (9.84 ft).
