Network Resilience for Colocation Data Centers
Give colocation operations teams and tenant infrastructure teams a secure, independent way to access and recover critical network equipment.
Colocation environments combine high equipment density, shared facilities, remote operations, and strict availability expectations. Gearlinx uses the NR4400 family to create a separate management layer around routers, switches, firewalls, servers, and other serial-managed infrastructure. Choose non-cellular models for wired out-of-band management or 4G LTE models when an additional carrier-based path is part of the resilience design.

Wired OOB

NR4416-4G / NR4448-4GAdd global 4G LTE with dual-SIM capability for an additional alternate access path.The Colocation Challenge
Dense infrastructure needs a recovery path that stays available.
Colocation facilities are designed for scale and availability, but infrastructure teams still need a reliable way to reach devices during network outages, change errors, maintenance events, and remote troubleshooting. The management layer should remain available even when the production network is the problem.
02
Remote operations
Network teams may be hundreds or thousands of miles from the facility when a configuration or connectivity problem occurs.
03
Shared dependencies
Carrier, cross-connect, routing, and facility dependencies can complicate diagnosis when normal access paths are degraded.
04
Change at scale
Turn-ups, upgrades, migrations, and configuration changes increase the need for a standardized recovery path.
How the Colocation Recovery Model Works
Keep a separate path from normal operations to recovery.
The NR4400 gives teams a practical out-of-band operating model for both day-to-day management and incident recovery inside colocation facilities.
01 / OPERATE
Run normally
Production traffic and customer services use the primary network while the NR4400 management layer remains available.
02 / DETECT
Identify the issue
Teams detect a failed path, configuration problem, device issue, or maintenance event that limits normal access.
03 / ACCESS
Reach the console
Use wired OOB or an LTE-enabled model to reach the affected infrastructure through a separate management path.
04 / RECOVER
Diagnose and restore
Review console output, troubleshoot, automate tasks, and restore service without waiting for the primary network.
05 / SCALE
Standardize the model
Repeat the same access and recovery design across racks, cages, rooms, facilities, or customer environments.
Cellular or Non-Cellular
Choose the alternate path that fits each colocation deployment.
The NR4400 family gives colocation teams the same core platform in both wired and LTE-enabled configurations, so connectivity can match the facility design rather than forcing one model everywhere.
Non-Cellular NR4400
Separate wired management network
Use NR4416 or NR4448 when the facility already provides an independent and resilient wired management path.
- 16-port or 48-port console density
- Two 1GbE RJ45/SFP ports plus two 10GbE SFP+ ports
- Dual AC power and passive cooling
- ZERO cloud management across the deployment
4G LTE NR4400
Add a carrier-based alternate path
Use NR4416-4G or NR4448-4G when the resilience design calls for cellular access in addition to the wired management network.
- Integrated dual-SIM global 4G LTE
- Same 16-port or 48-port platform choices
- Useful for independent access during wired path failures
- Managed through the same ZERO cloud platform
Reference Architecture
Build an independent management layer around the colocation environment.
Place the NR4400 alongside the infrastructure it protects, then use ZERO for centralized visibility and management across racks, rooms, and facilities.
The NR4400 family provides 16 or 48 software-selectable RS-232 serial ports, flexible 1GbE and 10GbE connectivity, automation capabilities, and optional global 4G LTE. All models are managed through ZERO.

NR4400 Family for Colocation
Two port densities. Cellular or non-cellular.
Colocation environments use the NR4400 family only. Select 16-port or 48-port density, then choose a standard wired model or an integrated 4G LTE model.
16-Port NR4400 Family
NR4416 / NR4416-4G
Use the 16-port platform for smaller cages, dedicated network rooms, or deployments that need lower console density without giving up the NR4400 management architecture.

FAQ
Questions about Gearlinx for colocation environments.
Answers for colocation operators and infrastructure teams evaluating a more resilient out-of-band management design.
Why is out-of-band management important in a colocation data center?
Colocation environments contain dense infrastructure that may need to be accessed during outages, maintenance windows, or configuration issues. A separate out-of-band management path helps teams retain access when normal network paths are unavailable.
Which Gearlinx products should a colocation use?
For this use case, Gearlinx uses the NR4400 family. The family includes 16-port and 48-port models in both non-cellular and global 4G LTE configurations.
When should we choose a 4G LTE NR4400?
Choose an LTE model when the facility design benefits from a carrier-based alternate access path in addition to wired management connectivity. LTE models include dual-SIM capability.
Can we use non-cellular NR4400 models in the same environment?
Yes. NR4416 and NR4448 provide the same core management architecture without integrated cellular. A colocation can mix cellular and non-cellular models based on the resilience requirements of each room, cage, or site.
What does ZERO provide across colocation locations?
ZERO provides centralized management, remote access, alerts, reporting, device and location visibility, warranty information, subscriptions, and lifecycle context across the Gearlinx fleet.
