SWITCH VOLKTEK NSH-561 : Layer 2 Managed 8-port 10/100TX plus 2 Gb Combo Switch

VOLKTEK NSH-561 : Layer 2 Managed 8-port 10/100TX plus 2 Gb Combo Switch

VOLKTEK's NSH-561 Managed Access Switch is equipped with eight 10/100Base-TX ports plus two combo Gigabit ports with RJ-45 (10/100/1000Base-T) and SFP slots (1000Base-SX/LX/LHX). 
The NSH-561 is RoHS-compliant.

It was designed with SNMP, RMON, flexible network management and monitoring options for increased efficiency and performance. Whether managing from an 'in-band' SNMP management station or Internet web browser, or 'out-of-band' on the RS-232 console port, the NSH-561 facilitates network monitoring and troubleshooting to make the switch very user friendly.
The NSH-561 is a feature-rich switch, offering VLAN capabilities, spanning-tree protocol, port isolation and much more. Special software features can also be added upon request.
With its Auto MDI/MDI-X and NWay capabilities, the NSH-561 is simple to deploy within a network. Additionally, the slim housing design is ideal for installation in locations with limited space and in applications requiring low port density. Once installed at any premise, the NSH-561 immediately connects the premise with the optical or copper Gigabit Ethernet ports, which provide high-bandwidth uplinks in flexible distances.
