Just a quick question... We have a fully populated quad hub with a HiperArc card and this afternoon it just start to go into a reboot cycle. This hub had a full load of calls (all modems in use). Once it came back up, it took calls and as soon as it got close to full it rebooted again. Could this be a problem with a power supply? The hub is running statically right now (not taking calls) and has not gone thru a reboot cycle on its own, so I am guessing it is a weak power supply. This hub has the (2) 45amp power supplies in it and is approx. 5 years old. Has anyone seen this and could it be a power supply? Thanks in advance!
