What Is MikroTik G1251-0250WNA?

The G1251-0250WNA is a removable power module designed for the CRS812 DDQ high-capacity switch.

Unlike open-frame internal power supplies that require the entire chassis to be opened, this PSU is built around a hot-swap design. A failed module can therefore be removed and replaced through the dedicated PSU bay while the other power source keeps the switch operational.

A typical redundant setup works like this:

AC power → PSU 1 + PSU 2 → CRS812 DDQ

If one PSU fails:

Working PSU → CRS812 remains online → Failed G1251-0250WNA replaced

Key Features of MikroTik G1251-0250WNA

1. 250W Power Capacity

The G1251-0250WNA is rated at 250W, making it suitable for the high-performance CRS812 DDQ platform. (MikroTik CDN)

Its output specification is:

12V × 20.8A = approximately 249.6W

which corresponds to the advertised 250W power class.

2. 12V DC Output

The PSU supplies 12V DC to the switch's internal power system. (MikroTik CDN)

This power remains internal to the CRS812 chassis; the module is not designed as a standalone 12V supply for unrelated devices.

3. High 20.8A Current Capacity

At 12V, the G1251-0250WNA can deliver up to 20.8A. (MikroTik CDN)

That high current rating supports the power needs of the CRS812 DDQ's high-speed switching hardware and related internal components.

For this reason, compatibility should be confirmed by product code rather than simply matching voltage and wattage.

7. Metal Enclosed Module

Unlike an open-frame power board, the G1251-0250WNA is built into a compact metal cartridge that slides into the switch's power-supply bay.

The design includes:

• Protective metal housing

• Ventilation openings

• Pull handle

• Locking/release mechanism

• Internal high-current connector

This makes it appropriate for frequent service and replacement in rack environments.

8. No RouterOS Configuration Required

The G1251-0250WNA is an electrical power module rather than a managed network component.

It does not have:

• RouterOS

• SwOS

• Ethernet ports

• IP address

• CPU

• Wireless interface

• WinBox interface

• User-configurable firmware

Once correctly inserted and supplied with power, it performs its PSU function automatically.

9. Suitable as a Spare PSU

Replacing the MikroTik G1251-0250WNA

In a redundant CRS812 setup, first verify which PSU has failed and make sure the other power supply is operating normally. The switch should remain powered by the working module while the failed PSU is removed.

Release the failed G1251-0250WNA using its front latch and handle, remove it from the PSU bay, and insert the replacement securely into the same slot. The hot-swap design means the CRS812 does not need to be restarted during this process when redundant power remains available.

After installation, verify that the replacement PSU has been recognized and that the switch's power status is normal. For mission-critical environments, monitoring PSU health and keeping a spare module on-site can help minimize recovery time.

The MikroTik G1251-0250WNA is a dedicated 250W hot-swap replacement power supply for the CRS812 DDQ, delivering 12V DC at 20.8A. Its primary value is redundancy: a failed PSU can be replaced without shutting down or restarting the switch when another power source remains active.

This makes the G1251-0250WNA particularly suitable for ISPs, data centres, enterprise networks and high-availability switching environments where taking a core switch offline for power-supply maintenance would be disruptive. MikroTik also specifies an MTBF of approximately 100,000 hours at 25°C.
