Emi; Lightning Protection; Rack-Mounting - HP MSR2000 Series Manual

 Place the removed memory module, CF card, or interface module on an antistatic workbench, with
the face upward, or put it into an antistatic bag.
 Touch only the edges, instead of electronic components when you observe or move a removed
memory module, CF card, or interface module.
To attach an ESD-preventive wrist strap:
Wear the wrist strap on your wrist.
1.
Lock the wrist strap tight around your wrist to keep good contact with the skin.
2.
Insert the ESD-preventive plug into the ESD-preventive socket.
3.
Make sure the rack is well grounded.
4.
CAUTION:
Check the resistance of the ESD-preventive wrist strap for safety. The resistance reading should be in the
range of 1 to 10 megohm (Mohm) between human body and the ground.

EMI

All electromagnetic interference (EMI) sources, from outside or inside of the router and application system,
adversely affect the router in a conduction pattern of capacitance coupling, inductance coupling,
electromagnetic wave radiation, or common impedance (including grounding system) coupling. To
prevent EMI, follow these guidelines:
Take measures against interference from the power grid.

Do not use the router together with the grounding equipment or lightning-prevention equipment of

power equipment, and keep the router far away from them.
Keep the router far away from high-power radio launchers, radars, and equipment with high

frequency or high current.
Use electromagnetic shielding when necessary.


Lightning protection

To better protect the MSR3000 router from lightning, do as follows:
Make sure the grounding cable of the chassis is well grounded.

Make sure the grounding terminal of the AC power receptacle is well 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 standard 19-inch rack, adhere to the following requirements:
The rack is equipped with a good ventilation system.

The rack is sturdy enough to support the router and its accessories.
