Direct answer for buyers
The MikroTik G1394-0350WNA is a replaceable AC hot-swap power module for the MikroTik CRS804 DDQ high-speed switch. Its primary role is to provide the switch with a compatible 350W power source and to support power redundancy when two matching modules are installed in the device. It is most relevant to data centres, AI and GPU labs, enterprise core or aggregation racks, research environments, and service providers operating the CRS804 DDQ. Before ordering, a buyer should confirm the exact switch model, the current power-module arrangement, the site input voltage, the number of modules required, and whether the purchase is for immediate replacement, planned maintenance stock, or a redundancy restoration project.
What this power supply does
The G1394-0350WNA converts compatible mains input into the low-voltage DC power required by the CRS804 DDQ. As a hot-swap module, it can be removed and replaced while the switch remains powered through the second operational module, provided the device is correctly configured and the remaining supply can support the active load. This is operationally valuable because a failed module does not automatically require a full shutdown window.
The product is not a general-purpose external adapter. It is a chassis-specific field-replaceable component. Its value therefore depends on exact compatibility, safe handling, and correct installation rather than on network features or software licensing.
Who should consider it
Organisations already operating, deploying, or standardising on the MikroTik CRS804 DDQ should consider the module when a power supply has failed, when redundant operation must be restored, or when an approved spare is needed at the site. It may also be included in a bill of materials for remote facilities where waiting for a replacement could extend operational risk.
It is not the correct choice for buyers seeking a power module for another CRS, CCR, router, server, or third-party switch. Similar ratings or physical appearance do not establish compatibility. The exact product code and host-device model must match.
Business problems the G1394-0350WNA helps address
Failed power module
A failed supply can remove redundancy and leave the switch dependent on one remaining power source. Replacing it with the correct module helps return the chassis to its intended dual-supply arrangement.
Maintenance without an outage
Hot-swap capability allows trained personnel to exchange the affected unit while the compatible switch continues running on the other supply. Site procedures and load conditions should still be reviewed before work begins.
Spare-parts planning
Keeping the exact replacement model available can reduce the period in which a critical switch operates without full power redundancy. Spare quantity should reflect site criticality and the number of deployed CRS804 DDQ units.
Procurement accuracy
The precise model code avoids confusion with other MikroTik hot-swap units, including power supplies designed for different switches or telecom DC input environments.
Product-fit decision matrix
| Requirement | Suitable when | Confirm before ordering |
|---|---|---|
| Replacement supply | An existing CRS804 DDQ module has failed or is suspected to be faulty. | Host switch model, fault diagnosis, existing module code, and required quantity. |
| Power redundancy restoration | The switch is operating on one module and the second bay must be returned to service. | Condition of the remaining supply, site load, and maintenance procedure. |
| On-site spare | The organisation needs a compatible spare for critical or remote infrastructure. | Number of installed switches, storage conditions, and spare-parts policy. |
| Different MikroTik chassis | Not suitable unless MikroTik documentation explicitly confirms compatibility. | Exact chassis model and manufacturer-approved power module. |
Verified technical information
Compatibility and dependency notice
This module is documented for the MikroTik CRS804 DDQ. Buyers should not select it solely from its 350W rating, connector appearance, or brand name. Other MikroTik devices may use power supplies with different voltages, mechanical guides, connectors, telemetry, airflow, or firmware expectations. A physically similar unit may still be unsuitable.
Hot replacement also depends on a healthy second supply, stable input power, correct rack access, and approved operating procedures. Where the switch carries critical traffic, the change should be planned by personnel familiar with the chassis and the organisation’s maintenance controls. FourTeck can help review the bill of materials and clarify whether the request is for an AC replacement unit, a spare, or a different regional or telecom power option.
A practical purchase and replacement journey
Identify the host device
Record the complete CRS804 DDQ model and the product code printed on the installed power module. Photographs of the rear panel and labels can help avoid ordering mistakes.
Define the reason
Clarify whether the requirement is failure replacement, redundancy restoration, planned spare stock, or expansion of a deployment. This affects quantity and urgency.
Review site power
Confirm mains voltage, rack power distribution, plug and cord needs, UPS connection, environmental conditions, and access to the rear of the chassis.
Request quotation
Share quantity, delivery destination, project timeline, and any installation or support expectation so the commercial scope can be prepared accurately.
Plan the change
Before installation, review redundancy state, alarms, remaining power capacity, ESD precautions, maintenance ownership, and rollback or escalation procedures.
Hot-swap serviceability and operational continuity
The main operational reason to choose the G1394-0350WNA is its role as a field-replaceable hot-swap power module. In a dual-supply CRS804 DDQ, each power unit contributes to a design that can tolerate the loss or removal of one supply while the other continues to power the chassis. This helps infrastructure teams replace a failed component without automatically scheduling a complete switch shutdown.
Hot-swap does not mean risk-free or procedure-free. The team should first confirm that the second module is healthy and that the switch is not reporting a broader power, thermal, fan, or environmental fault. The remaining input path should be connected to a stable source and should not be subject to simultaneous maintenance. It is also good practice to identify the affected module through the management interface or physical indicator before removal.
For critical environments, document the event, serial or asset information, alarm state, replacement time, and post-change checks. After installation, confirm that the new module is seated correctly, recognised by the chassis, and free of persistent fault indications. Where dual power feeds are used, verify that each feed continues to serve the intended supply. This approach turns a simple part replacement into a controlled continuity task rather than an improvised intervention.
Power redundancy as part of rack design
A redundant switch power design is effective only when the supporting power paths are also considered. Installing two supplies but connecting both to the same failing outlet, PDU, UPS, or branch circuit can leave a common point of failure. Organisations using the CRS804 DDQ in aggregation, AI, storage, or research networks should therefore examine how each G1394-0350WNA connects to the rack power architecture.
Where facilities allow, the two supplies can be mapped to separate PDUs or UPS-backed feeds. Labels should identify the upstream source for each module, and the cabling should avoid obstructing hot-swap access or airflow. Teams should also verify that rack-level power monitoring and capacity planning include the switch under realistic attachment and traffic conditions. The power module’s 350W rating is a capability of the unit; it does not mean the switch continuously consumes that amount.
For procurement, this wider view helps determine whether the order requires only the module or also power cords, rack power changes, maintenance support, or spare units. FourTeck can assist with requirement clarification, but final electrical design and site safety decisions should remain with qualified personnel familiar with the facility.
Spares strategy and lifecycle planning
Power supplies are wear-sensitive components exposed to heat, input fluctuations, dust, and sustained electrical load. Even when a manufacturer publishes a high mean time between failures, the figure is a statistical reliability measure under stated conditions rather than a promise for an individual unit. A practical spare-parts plan should therefore consider the number of CRS804 DDQ switches in service, the business impact of losing redundancy, the physical distance to each site, and vendor lead times.
A central data centre with on-site engineering coverage may use a shared spare pool. A remote lab or edge facility may need a dedicated local spare because travel and logistics could be slower than the organisation’s risk tolerance. Larger deployments may also choose to hold more than one unit so that a second fault does not exhaust the spare inventory. Storage conditions matter: the module should remain protected from moisture, contamination, impact, and uncontrolled temperature.
Asset records should distinguish the G1394-0350WNA from other MikroTik power modules. The model code, purchase date, storage location, intended host device, and warranty documentation should be recorded. When a spare is installed, the inventory record should be updated and a replenishment decision made promptly. This disciplined approach supports continuity without relying on unverified assumptions about immediate local availability.
Suitable business environments
AI and GPU labs
The CRS804 DDQ is positioned for high-bandwidth environments, including smaller AI and GPU clusters. In these settings, a compatible spare power module can support maintenance readiness for a switch carrying storage or compute traffic.
Enterprise aggregation racks
Where the switch aggregates multiple high-speed links, loss of power redundancy can increase operational exposure. The G1394-0350WNA helps restore the intended dual-supply arrangement after a module fault.
Research and technical labs
Lab schedules may involve long-running workloads, experiments, or demonstrations. A planned replacement module can reduce disruption when a supply issue occurs during active work.
Service-provider facilities
Operators using CRS804 DDQ switches in controlled network roles may include the module in a site spares plan. Compatibility and operational procedures should be standardised across the deployed estate.
Installation and operational considerations
Installation should be carried out by personnel familiar with rack-mounted electrical equipment and the CRS804 DDQ chassis. Before removing a module, verify the identity of the failed or inactive supply, check that the companion supply is operating normally, and ensure the switch load can remain supported. Do not rely only on visual assumptions; use available status indicators and management information where practical.
Maintain clear access to the rear of the switch. Power cables should be labelled and routed so they do not obstruct the module release mechanism or neighbouring equipment. Follow electrostatic discharge precautions and manufacturer safety guidance. When inserting the replacement, ensure it is aligned with the intended bay and fully seated without excessive force. Reconnect the correct input source and monitor for normal power status.
After the change, confirm that both power supplies are recognised and that there are no persistent alarms. Review switch operation, temperature, fan state, and event logs where available. In a critical environment, test the redundancy design only under an approved maintenance procedure; unplanned removal of a healthy supply can create unnecessary risk. FourTeck can coordinate product supply and discuss configuration or installation support requirements, but the exact service scope should be included in the quotation.
