## Summary description

Lancom SPSU-400-F2B is a dedicated power supply unit for access switches providing up to 400 W total power. It accepts an AC input of 100–240 V at 50/60 Hz and delivers stable power for network equipment. The unit is grey and designed for reliable continuous operation in networking environments where fixed AC mains compatibility is required.

## Long description

The Lancom SPSU-400-F2B is a dedicated 400 W power supply unit designed for access switches, specifically matching the airflow configuration of the LANCOM YS-7154CF-F2B model. It accepts an AC input of 100–240 V at 50/60 Hz and provides stable DC outputs to maintain continuous operation of the switch. The unit supports hot-swapping so it can be replaced during operation to minimise downtime and preserve network availability.
Advantages
The power supply delivers up to 400 watts and is built to the airflow orientation of the switch (front-to-back), ensuring compatibility and efficient cooling. Hot-swappable capability allows replacement without powering down the switch. Built-in protections for over-current, over-voltage and short circuits increase operational safety and help protect connected equipment.
Suitable for
LANCOM YS-7154CF-F2B access switches requiring a front-to-back power supply
Network environments that demand uninterrupted operation and easy serviceability
Racks and installations using 100–240 V AC mains at 50/60 Hz
Когда может не подойти
This specific SPSU variant is designed for front-to-back airflow (F2B) switch models; it is not suitable for switches that require a back-to-front (B2F) oriented power supply. If your switch uses the opposite airflow direction, choose the matching B2F unit instead.
Key specifications
Output power: 400 W total
Input voltage: 100–240 V AC, 50/60 Hz
Output voltages: +12 V at 37.5 A, +5 Vsb at 3 A
Hot-swappable design for replacement during operation
Protections: over-current, over-voltage, short-circuit
Operating temperature range: 0 °C to 40 °C
Colour: grey
How to use
Install the SPSU-400-F2B into the compatible LANCOM YS-7154CF-F2B power bay following the switch manufacturer’s insertion guide so the airflow orientation aligns with the chassis. Connect the unit to an AC mains source within the specified 100–240 V 50/60 Hz range. For hot-swap replacement, remove and insert the power supply while the switch remains powered, observing standard electrostatic discharge precautions and the vendor’s safety instructions.
What to consider before purchase
Confirm your switch model is LANCOM YS-7154CF-F2B (front-to-back airflow) and not the B2F variant
Ensure your installation provides 100–240 V AC at 50/60 Hz
Check rack cooling and ambient temperature to stay within 0 °C to 40 °C operating range
Usage recommendations
Use this 400 W SPSU as a redundant or replacement unit in access switch deployments that require continuous availability; pair with a second power supply for failover and follow the switch manufacturer’s hot-swap and safety procedures.
