Yes, it’s OK to briefly unplug and relocate a Hub provided its new location will be centrally located amongst its WorkPoints and maintain a strong network connection.
When locating a Hub in the office, try to place the hub in a hidden yet not buried location. Hubs, if not operating on a LAN, are operating off a wireless network and their location may obstruct the wireless signal. If possible, keep hubs in an open environment yet not in a location where they may be subject to tampering.
