Liebert vNSA

The Liebert vNSA is designed to connect multiple Liebert iCOM control devices. The Liebert vNSA contains either one or two powered industrial rail switches. An optional remote large display can be attached to the front door as well. All models have a power supply that requires connection to a single phase 120V or 240VAC power source. The enclosure features a key lock for security.

The Liebert vNSA supports autonegotiation, autopolarity and autocrossing, allowing for the use of standard network cables for connection to each port, rather than special crossover cables. The switch detects and makes adjustments for the network's speed and transmission mode, polarity and trans- mit-and-receive pins. See the Liebert vNSA user manual, SL-18840, for more details.

The number of ports available for connecting Liebert iCOM control devices varies by model as shown in Table 11. Models with a remote large display attached to the front door utilize one of the available Ethernet ports in the Liebert vNSA. Models with two switches utilize two ports to connect the switches.
