01 / ACCESS
Reach Infrastructure Securely
Maintain secure remote access to routers, switches, firewalls, servers, storage, PDUs, UPS systems, and serial devices when the primary path is degraded or unavailable.
Solutions / Out-of-Band Management
Modern Out-of-Band Management for Distributed Infrastructure
Deploy, manage, remediate, and recover critical infrastructure with secure remote access, an independent management network, LTE-enabled continuity, automation, and ZERO cloud management.
Gearlinx modernizes out-of-band management by bringing the NR4400, Duckfone, Gearlinux, ZERO, and ORAAS together into one Total OOB® platform. The result is a secure recovery path and a practical operating model for data centers, colocations, enterprise edge, branch locations, retail sites, and remote infrastructure.

What Modern OOB Requires
Out-of-band management is more than a console connection.
Legacy out-of-band tools focus on basic access. Modern distributed infrastructure needs a broader operating model that preserves independent access, separates the management path from the production network, enables automation, and supports remote recovery at scale.
02 / SEPARATION
Keep the Management Path Independent
Use a separate management network so teams are not trying to manage the network with the same network that is unavailable.
03 / AUTOMATION
Deploy and Operate Efficiently
Support Zero Touch Provisioning, containers, APIs, and repeatable remote operations so teams can deploy, configure, and manage infrastructure with less manual effort.
04 / RECOVERY
Recover Remotely
Give operations teams the practical control needed to diagnose issues, remediate configurations, restart services, and restore infrastructure without traveling to the site.
Total OOB® Architecture
Build a management path that still works when the primary network does not.
Gearlinx Total OOB® starts with a secure, independent management and connectivity layer. It then adds centralized ZERO cloud management, automation, and lifecycle visibility so teams can access, manage, remediate, and recover infrastructure across distributed environments.

↓Modern out-of-band management works best when access, automation, cloud management, and lifecycle information are already part of the operating model before disruption occurs.
The Out-of-Band Lifecycle
Access is only the start. Modern OOB should help teams recover.
A strong out-of-band strategy supports the full cycle from issue detection to remote recovery. Gearlinx connects that cycle through independent access, cellular continuity, automation, and centralized management.
01
DetectRecognize that the production path is impaired, unstable, or unavailable.
02
AccessUse the independent management network to securely reach the affected infrastructure.
03
DiagnoseInspect devices, logs, status, and connectivity to understand the issue remotely.
04
RemediateReconfigure, restart, automate, or otherwise correct the problem without traveling to the site.
05
RecoverRestore service, validate the environment, and return the site to normal operations faster.

Centralize lifecycle visibility
Bring locations, serial numbers, warranty status, subscription status, support coverage, and asset context into one management view.
FAQ
Out-of-band management questions buyers ask.
Answers to common questions about secure remote access, Total OOB®, independent management networks, LTE continuity, ZERO, and distributed infrastructure recovery.
What is out-of-band management?
Out-of-band management is a secure, separate management path used to access and manage critical IT infrastructure when the production network is unavailable, impaired, or misconfigured. It gives teams a way to reach routers, switches, firewalls, servers, power systems, and remote infrastructure without relying on the primary network.
How is Gearlinx Total OOB® different from legacy out-of-band management?
Gearlinx Total OOB® brings together secure remote access, LTE-enabled continuity, automation, centralized ZERO cloud management, and lifecycle visibility. It goes beyond a basic console connection by helping teams deploy, manage, remediate, and recover distributed infrastructure remotely.
Why does out-of-band management need a separate management network?
A separate management network keeps the access path independent from the production network. If the primary network goes down, teams still have a secure way to reach and recover critical infrastructure.
What does ZERO provide for out-of-band management?
ZERO provides centralized cloud management for Gearlinx fleets and third-party devices, including locations and asset data, warranty and subscription visibility, alerts, reporting, remote operations, and lifecycle context.
How do the NR4400 and Duckfone support out-of-band management?
The NR4400 provides high-density Total OOB® with secure remote access, automation, edge compute, and optional global 4G LTE. Duckfone provides compact 4G LTE connectivity and out-of-band access for branches, retail, enterprise edge, and remote sites.
Where is out-of-band management used?
Out-of-band management is used across data centers, colocation facilities, branch offices, enterprise edge, retail environments, kiosks, and remote infrastructure where teams need a reliable recovery path and remote operational control.
