Step 1:

Remove the MC200LE-VZ Wireless Modem from the CBA750B Router

If the CradlePoint MC200LE-VZ wireless modem is attached to the CBA750B router, the modem must be

removed in order to enable Passthrough mode on the CBA750B router and insert a Verizon subscriber

identity module (SIM) card into the wireless modem. If the wireless modem is already detached from the

router, you may skip this step. To remove the MC200LE-VZ wireless modem from the CBA750B router,

follow these steps:

1. Remove the three screws on the bottom of the assembly that affix the modem to the router.

Remove the modem from the router.

Step 2: Enable Passthrough Mode

The CradlePoint CBA750B can operate in two modes either Router or Passthrough. Passthrough mode

forces the integrated USB wireless modem to pass IP packets through to the LAN Ethernet port without the

attached router performing any routing functions. In this mode, load balancing is disabled, the Routing

Mode is set to IP Passthrough, the Subnet Selection Mode is set to Automatically Create Subnet, and

any secondary networks are disabled. The CBA750B must be in Passthrough mode to properly operate

with the AOS router.

A miniature, sliding switch on the right side of the CBA750B is used to toggle between Router mode and

Passthrough mode; however, this switch is obstructed by the wireless modem when it is installed.

Consequently, the modem must first be removed from the router to access the switch.

By default, Passthrough mode is enabled; however, because this setting is necessary for the

operation of the CBA750B with ADTRAN routers, you should verify that this mode is enabled

by following the steps below.

To enable Passthrough mode on the CBA750B, follow these steps

The following sections provide general instructions for configuring the CradlePoint

CBA750B for integration with an ADTRAN Router. Refer to the CradlePoint CBA750B User

Manual for detailed instructions on how to configure the CBA750B.
