RB750UP

RB750UP is a small five port ethernet router in a nice plastic case, the UP model includes a USB 2.0 port and PoE output. Ports 2-5 can power other PoE capable devices with the same voltage as applied to the unit. Less power adapters and cables to worry about. Max current is 500mA per port, Ethernet ports are shielded.

It is affordable, small, good looking and easy to use - It’s probably the most affordable MPLS capable router on the market. No more compromise between price and features - RB750 series has both. With it’s compact design and clean looks, it will fit perfectly into any SOHO environment.

Box contains: RB750UP, plastic case, 24v 2.5A power adapter

All throughput tests done with Xena Networks specialized test system and RouterOS v5, according RFC2544, with Ethernet frame sizes 64, 512, 1518 bytes.
Each board is tested with specified number of Ethernet interfaces, to ensure optimal load on hardware.
Values in Italics indicate that the maximum possible throughput was reached, limited only by ethernet ports themselves.
