2 Installing the device
IMPORTANT:
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" are met.

Mounting the device on a workbench
CAUTION:
•To avoid damaging the device and affecting heat dissipation, do not place heavy objects on the
device.
•Make sure the workbench is anti-static.

2-3
The workbench-mounting procedure is similar for WX1800H series access controllers. The following
procedure uses the WX1804H-PWR access controller as an example.
To mount the device on an anti-static workbench:
1. Place the device upside down on the workbench. Use a cloth to clean the recessed areas on
the bottom.
2. Attach rubber feet to the four recessed areas.
3. Place the device upside up on the workbench. Make sure the four rubber feet stand firmly on
the workbench.
Figure2-3 Mounting the device on a workbench
Mounting the device in a 19-inch rack
IMPORTANT:
As a best practice, reserve a clearance of 1U/44.45 mm (1.75 in) between adjacent devices for
adequate heat dissipation.
Only the WX1810H-PWR and WX1840H access controllers support rack mounting. The following
procedure uses the WX1840H access controller as an example.
To mount the device in a 19-inch rack:
1. Wear an ESD wrist strap. Make sure the rack is sturdy and is reliably grounded.
2. Use a mounting bracket to mark the cage nut installation positions on the front rack posts.
Install cage nuts.
Figure2-4 Installing cage nuts

2-4
3. Use the M4 screws supplied with the mounting brackets to attach the mounting brackets to both
sides of the device.
Figure2-5 Attaching the mounting brackets to the device
4. Supporting the bottom of the device with one hand and holding the front of the device with the
other, put the device in the rack. Use M6 rack screws and cage nuts to attach the mounting
brackets to the front rack posts, as shown in Figure2-6. Make sure the device is installed
securely in the rack.

Connecting the grounding cable
CAUTION:
•Correctly connecting the grounding cable is crucial to lightning protection and EMI protection. To
install and use the device, first connect the grounding cable reliably for the device.
•Connect the grounding cable to the grounding system in the equipment room. Do not connect it
to a fire main or lightning rod.
Attaching the ring terminal to a grounding cable
No grounding cable is provided with the WX1804H-PWR or WX1820H access controller. You need to
purchase a grounding cable and attach the ring terminal provided with the access controller to the
grounding cable.
The WX1810H-PWR and WX1840H access controllers each are provided with a grounding cable
that has a ring terminal attached.
To attach the ring terminal to a grounding cable:
1. Cut the grounding cable to a length as required by the connection distance.
2. Use a wire stripper to strip 5 mm (0.20 in) of insulation off the end of the grounding cable.
3. Slide the heat-shrink tubing onto the cable and insert the bare metal part into the end of the ring
terminal.
4. Use a crimper to secure the metal part of the cable to the ring terminal.
5. Slide the heat-shrink tubing down the cable until the tube covers the joint.
6. Use a heat gun to shrink the tubing around the cable.

Connecting the grounding cable
Grounding the device by using a grounding strip
The WX1800H series access controllers use the same procedure for grounding by using a grounding
strip. The following procedure uses the WX1804H-PWR access controller as an example.
To ground 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.

2-6
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.
Figure2-8 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.
The WX1810H-PWR and WX1840H access controllers support grounding by using a grounding
point on the rack. The following procedure uses the WX1840H access controller as an example.
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.

2-7

Grounding the device by using a grounding conductor buried in the earth
The WX1800H series access controllers use the same procedure for grounding by using a grounding
conductor buried in the earth. The following uses the WX1840H access controller as an example.
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 a grounding conductor. Weld the 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.
The network port lightning protector installation procedure is the same for the WX1800H series
access controllers. The following procedure uses the WX1840H access controller as an example.
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, and insert the cable from the
network port into the Protect end.
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 the AC power line routed from outdoors to thestrip
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.
