Server rackThis is server rack 1 of 2. You can see that servers are labeled and our EMC AX4 3 chassis array in the middle of the rack right above our Dell M1000e blade server chassis. Below that and out of the picture is an APC UPS. To the left of the rack, you'll notice the very large power connectors; these massive connectors replaced what was a hardline power connection to the UPSs, making it possible for us to disconnect them, if necessary, without involving an electrician.
