iDirect HUB chassis

I have 2X iDirect satellite hub 15000series with 20 iSCPC modems. Im wondering if its technically allowed to shut the hub down after end of our working hours (which its about 12 hour/day) and will that effect registering my remote sites on the next day after starting the hub??? people says it will effect registering remotes for reasons related to synchronization and frequancy hopping and some thing like that. I sent iDirect message explaining that and now I'm waiting for the answer but I'm in a hurry and so confused. Can any one help me in this area.

thanks in advanced
