Preparing for installation
Safety recommendations
W
ARNING!
Before installation and operation, read all of the safety instructions in
Compliance and Safety Guide
supplied with your router.
Follow these general safety recommendations:
•Turn off all power and remove all power cables before opening the chassis.
•Unplug all power and external cables before moving the chassis.
•Before installation, locate the emergency power switch so that you can shut off power
immediately if necessary.
•Always wear an ESD wrist strap when installing the router.
•Do not stare into an open optical interface. The light can cause permanent eye damage.
•Use a good grounding system. This is essential for reliable operation.
•Make sure the resistance reading between the chassis and the ground is less than 1 ohm.
Examining the installation site
The H3C MSR900-E router can only be used indoors. To ensure that the router can operate correctly
and prolong its service lifetime, the installation site must meet the following requirements.
Temperature and humidity

Cooling system
To ensure good ventilation, the installation site must meet the following requirements:
•A minimum clearance of 10 cm (3.94 in) is reserved at the inlet and outlet air vents.
•The site has an adequate cooling system.
ESD prevention
CAUTION:
Make sure the resistance reading between human body and the ground is in the range of 1 to 10
megohms (Mohms).
To prevent the electronic components from being damaged by ESD, follow these guidelines:
•Make sure the router and the floor are reliably grounded.
•Take dust-proof measures for the equipment room.
•Always wear an ESD wrist strap when touching a circuit board.
To attach an ESD wrist strap:
1. Wear the wrist strap on your wrist.
No wrist strap is supplied with the router. Prepare it yourself.
2. Lock the wrist strap tight around your wrist to keep good contact with the skin.
3. Secure the wrist strap lock and the alligator clip lock together.
4. Attach the alligator clip to the grounding terminal on the device.
EMI
EMI from any source adversely affects the router.
To prevent EMI, use the following guidelines:
•Use electromagnetic shielding when necessary.
•Take measures against interference from the power grid.
•Do not use the router together with the grounding or lightning-prevention equipment of power
equipment, and keep the router far away from them.
•Keep the router far away from radio transmitting stations, radar stations, and high-frequency
devices.

3
Lightning protection
To protect the router from lightning, use the following guidelines:
•Make sure the grounding cable of the chassis is grounded reliably.
•Make sure the grounding terminal of the AC power receptacle is grounded reliably.
•Install a lightning arrester at the input end of the power supply.
Installation accessories and tools
Figure 1 and Figure 2 list the accessories and tools required for installing the router.
