Cradlepoint 170700-000 COR Extensibility Dock for IBR900 and IBR600C Series

Compact routers trade expandability for size — until you dock them. The Cradlepoint 170700-000 COR Extensibility Dock turns a small COR router (IBR900, IBR600C/IBR650C or R500-PLTE; Cradlepoint's list also covers IBR600B series) into a far more capable edge node without moving to a larger platform. The headline is the MC400 expansion slot: add a second modem for dual-modem operation — separate carriers for failover, or split traffic across networks — a capability normally reserved for Cradlepoint's larger chassis. Pair an MC400LP6 or MC400LPE modem and the dock also adds GPS functionality for fleet tracking and location-aware policy. Beyond the modem bay, the dock supplies two extra 10/100 Ethernet ports for local devices, supports third-party expansion cards, and exposes a 2x10 connector carrying serious integration hooks: additional GPIOs (one dedicated input plus four configurable I/O), 5 V DC at 50 mA to power external sensors, and ignition sensing for vehicle power management. It is also capable of redundant power supply operation — relevant for installations that cannot tolerate a power-path failure. In practice the dock anchors advanced vehicle builds (dual-carrier connectivity plus GPS plus ignition logic) and industrial cabinets that need Ethernet, sensor power and I/O in one integrated stack rather than scattered accessories.
