NORTEL BES 120-48T-PWR 50PORTS POE SWITCH...

Nortel BES 120-48T-PWR 50Ports POE Switch...

The Switch is same performance as the Cisco Catalyst 2950-48 Familly and the 3550-48 familly.

The Switch has an excellent physical and working condition, fully tested by a Cisco Engineer. I did restore the switch to Factory Default.

It can be managed via a Web Browser, GUI Manageable, or the Command Line Interface. Very easy to administer. Ideal for Small and Medium size business as an access layer, and for powering IP Phones and IP Cameras.

The Switch will come with AC Power Cord, Rack Mounts and Console Cable, as the case for all our equipments.
