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.
• Confirm that the resistance between the chassis and the ground is less than 1 ohm.
Site requirements
The router can only be used indoors.
This section provides information about temperature, humidity, cleanness, and air quality requirements,
as well as rack-mounting requirements and protection against damage from lightning and EMI.

To prevent overheating:
• Provide adequate clearance for air flow, including at least 10 cm (3.94 in) ventilation space
around the router's air intake and outlet vents.
• Make sure the site has an adequate cooling system.
ESD prevention
To prevent the electronic components from being damaged by ESD, follow these guidelines:
• The equipment and floor are correctly grounded.
• The equipment room is dust-controlled.
• Wear an ESD wrist strap when inspecting or handling 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. Insert the ESD plug into the ESD socket in the chassis.
4. Attach the alligator to the chassis.
IMPORTANT:
Check the resistance of the ESD 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
EMI from any source adversely affects the router.
To prevent EMI:
• Use electromagnetic shielding when necessary.
• Take measures against interference from the power grid.
• Position the router as far as possible from any power source's grounding equipment or light-
prevention equipment.
• Position the router as far as possible from radio transmitters, radar, and all high-voltage or high-
frequency equipment.
Lightning protection
To protect the router from lightning:
• Make sure the grounding cable of the chassis is grounded correctly.
• Make sure the grounding terminal of the AC power receptacle is grounded correctly.

• Install a lightning arrester at the input end of the power supply.
Installation accessories and tools

Installing the router
W
ARNING!
To avoid injury, do not touch bare wires, terminals, or parts with high-voltage hazard signs.
IMPORTANT:
• The barcode on the router chassis contains product information that must be provided to local sales
agent before you return a faulty router for service.
• Keep the tamper-proof seal on a mounting screw on the chassis cover intact, and if you want to open
the chassis, contact H3C for permission. Otherwise, H3C shall not be liable for any consequence.
Installation prerequisites
• You have read "Preparing for installation" carefully.
• All requirements in "Preparing for installation" ar
e met.
Installation flowchart
You can install the router on a workbench, on a wall, or in a rack. Select an installation method
according to the installation environment, and follow the installation flowchart shown in Figure 3.

Installing the router
Mounting the router on a workbench
IMPORTANT:
• Reserve a space of 10 cm (3.9 in) around the router for heat dissipation.
• Do not place heavy objects on the router.
To mount the router on a workbench:
1. Make sure the workbench is clean, stable, and correctly grounded.
2. Place the router upside down on the workbench and attach the rubber feet to the four round
holes in the chassis bottom.

the router on a wall, position the router so the network interfaces face downwards,
and the sides with ventilation openings are perpendicular to the ground, as shown in Figure 5.
To mount the router on a wall:
1. Mark the locations of the two mounting holes on the wall with a separation of 160 mm (6.30
in).
The holes must be level (on the same horizontal line.)
2. Drill two holes in the wall.
3. Following the marks, drill the two holes at least 22 mm (0.87 in) deep.
Verify that the holes are level.
4. Insert an anchor into each hole so it is flush with the wall surface.
5. Drive a screw into each anchor, keeping the screw heads protruding at least 1.5 mm (0.06 in)
from the wall.
6. Hang the router on the screws.

Installing the router in a rack
IMPORTANT:
To avoid damages to the router and mounting brackets, do not place objects on the router.
To install the router in a rack:
1. Mark locations of the cage nuts on the front rack posts based on holes in the mounting brackets,
as shown in Figure 6.
The mounting
brackets on both front rack posts must be level (on the same horizontal line.)

Grounding the router
W
ARNING!
Connecting the router grounding cable correctly is crucial for protecting the router from lightning and
EMI.
Make sure the grounding resistance is less than 5 ohms.
You can ground the router with a grounding strip or to a buried grounding conductor.
The router provides only a ring terminal but no grounding cable. Purchase a grounding cable if
necessary.
11
Attaching the ring terminal
1. Cut the grounding cable as appropriate for connecting to the grounding strip.
2. Peel 5 mm (0.20 in) of insulation sheath by using the wire-stripping pliers, and insert the bare
metal part through the black insulation covering into the end of the ring terminal.
3. Secure the metal part of the cable to the ring terminal with needle-nose pliers.
4. Cover the joint with the insulation covering, and heat the insulation covering with a blow dryer
to completely cover the metal part.
Figure 10 Attaching the ring terminal
Grounding the router through the rack
1. Make sure the rack has been correctly grounded.
2. Remove the grounding screw from the router chassis.
3. Put the ring terminal of the grounding cable on the grounding screw.
4. Use a screwdriver to fasten the grounding screw.
5. Remove the nut from the grounding post of the rack.
6. Use the needle-nose pliers to bend the bare wire at the other end of the grounding cable.
7. Hook the grounding cable to the grounding post on the rack, and secure the nut.
