Before You Begin

To ensure that the CR4250 High-Performance Branch router performs optimally, consider the location and environmental temperatures before installing.

Keep the device away from reflective and metallic surfaces as they may interfere with signal reception.
Avoid mounting the router in locations that experience extreme heat or cold.
The CR4250 may be set up on a flat surface or mounted in a mounting bracket. If mounting in a mounting bracket, purchase and prepare the CR4250
Rack Mount prior to setup.
Refer to the CR4250 Safety, Regulatory, and Warranty Guide (included with your hardware) for more information about location considerations.

NOTE: Cradlepoint recommends that all Branch devices be installed by a professional. For assistance with installation or in locating a professional installer, contact Cradlepoint Sales and Support (https://cradlepoint.com/company/contact_us).

Understanding LEDs

Product Overview

INDICATOR	BEHAVIOR

Status LED

| Power: The CR4250 must be powered using an approved power source. Input requirements: 100-240V, 50-60Hz; 1.7A max without PoE, 4.1A max with PoE.

LED Off = normal operation
Blinking Green (1Hz) = upgrade in progress OR a button is currently pressed Blinking Green (4Hz) = shutdown in progress
Blinking Orange (4Hz) = factory reset in progress

Power LED

|

Green = Powered ON and hardware OK
No Light = Not receiving power. Check the power source connection
