I'm rather pressed for space, this gear is in a tiny cupboard also
storing the traditional contents of a utility room and garage. I'd
manged to allow myself 1 shelf, 30cm x 50cm x 20cm for the UPS gear.
That might just be enough space to squeeze in a UPS and a 120Ah SLA
battery, which would keep both up for at least 6h, hopefully enough to
span most outages. For outages longer than that, I'd probably not mind
losing my DHCP leases anyway. Are there any specific requirements for
the attached batteries, or will any 12V SLA battery suffice? It's just
a shame that no UPS units offer a WOL option for waking up attached
