Powering M1XEP from M1G power supply

Does anyone foresee a problem with powering the M1XEP ethernet adapter from the M1G control's power supply rather than the ac/dc adapter that comes with the xep? Is anyone running a system this way?

Edit: This is assuming that you stay within the 1 amp load limitation of the control.
 
At 300mA it takes 1/3rd of your M1's power quota.   So it's a big hit.  But people have done it.
 
If the rest of your network is not on battery backup it provides no value in having it up during a power outage and if the rest of your network is on battery backup then it might be better just to add the adapter to that.
 
I located the power supply on my computer rack (with UPS), picked up a couple of M/F barrel connectors at ratshack and made an "extension cord" from the power supply to the XEP.   That way I didn't have to cut up the power supply cord.
 
I generally prefer to do this wherever possible, then run it through a relay to enable a remote reboot (if needed) or drive the same via rules.

Interesting, can you give me an example where you have had a need to reboot the xep remotely?

I have a customer's site where the XEP remains on the network with a static IP and static port config and at random times, while the unit is still pingable, RP will not connect to it (they use it often to add/remove user credentials for access control).
 
My own personal unit, with reserved DHCP address and static configuration does similar and/or my DNS stops updating properly (even with the service running on an external machine to update and ping the DNS server) and while RP can connect to it on the LAN, the WAN seems to fail occasionally. Might have to do with Uverse and their gateway. Too lazy too look into it further.
 
In a customer's situation, it's pretty easy to automate and tie into a consumer router/switch and modem to force a reboot remotely, same with the XEP. Far easier to do this as a troubleshooting step instead of rolling a truck. Same goes for most situations...customer on vacation but can't get their app or what have you to connect remotely...easy enough to dial in (yay POTS!) and do a remote reboot.
 
Usually I'm putting in a M1RB or XOVR or both and usually have spare outputs to burn. That and a DPDT relay can be pretty easy to do.
