About This Device
The MC400 Modular Modem combines enterprise reliability with Gigabit-class LTE performance, and this BB packaging brings it to the CBA850 LTE branch adapter - Cradlepoint's dedicated failover appliance. Rated for 1200 Mbps LTE Advanced Pro with DC-HSPA+ and WCDMA fallback, the compact silver module (about 2.8 in deep, half an inch tall) slots in over a USB host interface and ships with the CBA85x door to close the bay properly. The upgrade logic mirrors the rest of the MC400 program: as primary circuits grow, the failover path upgrades by module - to Gigabit-class LTE today, without replacing the CBA850 that branches already trust.
Failover that cannot carry the branch's real load is theater - module-level upgrades keep the backup path honest as primary circuits scale.
Power down the CBA850, slot the MC400, fit the included door, and bring the adapter back online. Verify LTE registration and run a failover test against the primary circuit before leaving site.
Cloud Care Networks stocks the Cradlepoint BB-MC400-1200M-B alongside the gateways and routers it supports, so IT and field-service teams can consolidate antennas, spares, and replacement hardware on a single order.
