www.support.3com.com for a list of access points supported by 3Com 
Corporation).

 

Installing the ECB

 

1 Remove your ECB from the packaging. The ECB ships fully 

assembled. To install the PC Card and use the ECB, some 
disassembly and reassembly is required.

2 Remove the cap from the ECB by pulling on the side of the cap to 

release it as shown in the following figure. When you remove the 
cap, you will see the PC Card slot.

3 If you are planning to mount the ECB on the wall or ceiling 

(optional), remove the bottom mounting plate as shown in the 
following figure.

NOTE: 

 

The ECB package does not include a Wi-Fi-compliant wireless 

LAN PC Card. These cards are sold separately.

4 Remove the small combs from the end cap. The combs are 

generally not needed, but when cut to an appropriate size they 
prevent the PC Card from vibrating out of the socket when the 
ECB is in an environment with extreme vibrations.

5 Gently insert the PC Card (face up) into the slot as shown in the 

following figure.

6 Replace the cap, which you removed in step 2, by snapping the 

cap straight down on the body.

7 If you are mounting the ECB on a wall or ceiling, install the bottom 

mounting plate, which you removed previously, where desired. After 
the mounting plate is installed, place the ECB onto the mounting 
plate and snap it into place. Ensure that the ECB is secure.

8 Connect a standard straight-through 10BASE-T Ethernet cable 

between the RJ-45 port (ECB ports and connectors are shown 
below) on the ECB and the network port on the computer where 
you will install the ECB Configuration Utility software.

9 Connect the six-pin DC power cable to the power adapter.

10 Connect the AC power cord to the other side of the power adapter.

11 Connect the round power plug to the ECB power jack labeled 5 VDC.

12 Insert the AC power cord into an AC socket.

13 Verify that the Ethernet LED on the ECB is illuminated.

14 The ECB hardware is now ready for configuration using the ECB 

Configuration Utility software. Refer to the following section.
