Installing the device
WARNING!
Keep the tamper-proof seal on a mounting screw on the chassis cover intact, and if you want to open
the chassis, contact H3C Support for permission. Otherwise, H3C will not be liable for any
consequence caused thereby.
The installation procedure is the same for the WX3800H series access controllers.This section uses
the WX3840H access controller as an example.
Confirming installation preparations
Before you install the device, verify that you have read "Preparing for installation" carefully and the
installation site meets all the requirements.

Installation flow
Figure 1 Installation flow
Mounting the device on a workbench
CAUTION:
Do not place heavy objects on the device.
If a standard 19-inch rack is not available, you can mount the device on a clean, flat workbench.
To mount the device on a workbench:

3
1. Place the device upside down. Clean the recessed areas on the chassis bottom.
2. Attach the four rubber feet to the recessed areas on the chassis bottom.
3. Place the device on the workbench with the upside up. Make sure the four rubber feet stand
firmly on the workbench.

Installing the device in a 19-inch rack
IMPORTANT:
Keep a minimum distance of 1 U (44.45 mm, or 1.75 in) between adjacent devices for good heat
dissipation.
Mounting bracket
Figure 3 Mounting bracket
Mounting the device in a rack
1. Attach cage nuts to the front rack posts:
a. Wear the ESD wrist strap and make sure the rack is stable and is reliably grounded.
b. Use a mounting bracket to mark cage nut installation positions on the two front rack posts.
c. Install cage nuts into the marked square holes on the front rack posts.

4
Figure 4 Installing cage nuts
2. Use the M3 screws supplied with the mounting brackets to secure the mounting brackets to
both sides of the device.
Figure 5 Installing the mounting brackets
3. Supporting the device bottom with one hand and holding the device front with the other, place
the device gently in the rack. Use M6 rack screws toattach the mounting brackets on the device
to the front rack posts.

Grounding the device
WARNING!
•Correctly connecting the grounding cable is crucial to lightning protection and EMI protection.
•Connect the grounding cable to the grounding system in the equipment room. Do not connect it
to a fire main or lightning rod.
Grounding the device by using a grounding strip
1. Connect the grounding cable to the device.
a. Use a Phillips screwdriver to remove the grounding screw from the grounding hole in the
rear panel of the chassis.
b. Use the grounding screw to attach the ring terminal of the grounding cable to the grounding
hole and fasten the screw.
2. Connect the other end of the grounding cable to the grounding strip. Make sure the grounding
strip is reliably grounded.

Figure 7 Grounding the device by using a grounding strip
Grounding the device by using a grounding point on the rack
CAUTION:
To ground the device by using a grounding point on the rack, make sure the rack is reliably
grounded.
To ground the device by using a grounding point on the rack:
1. Connect the grounding cable to the device. For the connection procedure, see "Grounding the
device by using a grounding strip."
2. Connect the other end of the grounding cable to a grounding point on the rack.

Grounding the device by using a grounding conductor buried
in the earth
If earth is available at the installation site, hammer a 0.5 m (1.64 ft) or longer angle iron or steel tube
into the earth to serve as agrounding conductor. Weldthe yellow-green grounding cable to the angel
iron or steel tube and treat the joint for corrosion protection.

(Optional) Installing network port lightning
protectors
IMPORTANT:
•Before installing a network port lightning protector, read the instructions in the document that
comes with the protector.
•Network port lightning protectors are available only for 10M/100M/1000M RJ-45 Ethernet coppe
r
ports.
•If multiple network ports have network cables routed outdoors, install a network port lightning
protector for each network port.
If part of the network cable for a network port is routed outdoors, install a network port lightning
protector for the port to protect against damages caused by lightning strikes.
No network port lightning protectors are provided with the device. Purchase them yourself as
required.
To install a network port lightning protector for a network port:
1. Use a double-faced adhesive tape to stick the network port lightning protector onto the device
chassis, and make sure it is as close to the grounding screw of the device as possible.
2. Cut the ground wire of the protector to a length (as short as possible) as required by the
distance between the protector and the grounding screw of the device. Attach the ground wire
securely to the grounding screw of the device.
Make sure the grounding screw of the device is reliably grounded.
3. Use a multimeter to verify that the ground wire of the protector makes good contact with the
grounding screw of the chassis.
4. Insert the outdoor network cable into the protector's Surge end marked IN, and insert the cable
from the network port into the Protect end marked OUT.
5. Examine the port LED to verify that the port is operating correctly.

(Optional) Installing a surge protected power strip
IMPORTANT:
Before installing a surge protected power strip, read the instructions in the document that comes
with the strip.
If you use an AC power line routed from outdoors for the device, use a surge protected power strip
for the device to protect against damages caused by lightning strikes. No surge protected power strip
is provided with the device. Purchase one yourself if required.
To use a surge protected power strip, first connect theAC power line routed from outdoors to the strip
and then connect the power cord from the device to the strip.
You can attach the surge protected power strip to the rack, workbench, or wall of the equipment
room.
Connecting interface cables
Connecting the console cable and setting terminal
parameters
To configure and manage the device from the console port, you must run a terminal emulator
program, TeraTermPro or PuTTY, on your configuration terminal. For more information about the
terminal emulator programs, see the user guides for these programs
The following are the required terminal settings:
•Bits per second—9600.
•Data bits—8.
