Can the power module of AR2240-S be moved to the back of the router

1

The power module on the front panel of AR2240-S cannot be moved to the back panel.
Slots on the front panel of AR2240-S are specified for the power module and SRU respectively. Slots on the back panel are used to install service cards.

Differences between a PoE power module and a common power module on an S series switch
A PoE power module and a common power module on an S series switch have the following differences: Appearance: On fixed switches, a PoE power module has a fan, but a common power module does not. PoE and common power modules are not distinguished on modular switches (S7700, S9700, S9300, and S12700). The modular switches need to support the PoE function and power modules in PoE slots. Function: A PoE power module can provide power for both the entire switch and the PDs, whereas a common power module can provide power for only the entire switch.

PoE power module of an S series switch
Configuration and power of PoE power modules on S series switches are as follows: The fixed series switches that have PWR or PWH in their names support PoE. 1. You can use Hardware Query Tool to query the configuration and power of PoE power modules on S series switches. 2. Among modular switches (S7700, S9700, S9300, and S12700), only the S7700 and S9300 support the PoE function. If a switch is running V200R006 or a later version, it allows 800 W AC, 2200 W AC, and 2200 W DC power modules in PoE power slots. If the input voltage is 220 V AC, the PoE power is 800 W or 2200 W. If the input voltage is 110 V AC, the PoE power is 400 W or 1100 W (the S7712 and S9312 do not support 110 V AC). Only ES0D0G48VA00 cards of the S7700 and LE0DG48VEA00 cards of the S9300 support the PoE function. Dual power modules with the same power can be installed to provide power for PDs in load balancing mode. The total power is the sum of two power modules. The number of PoE interfaces supported by a switch is the result of dividing the available PoE power by 15.4 W (802.3af), 30 W (802.3at), or 60 W (802.3bt). Generally, a 250 W power module supports eight interfaces of 15.4 W. A 500 W power module supports 24 interfaces of 15.4 W and 12 interfaces of 30 W. For details, see Tell You About PoE.
