Optimizing data flow has never been simpler than the WS-C3750-48PS-S makes it. Because each of the 48 x 10/100 Ethernet ports is backed up by amazing internal hardware features, you may never have to worry about traffic slowdowns again.
In addition to auto-negotiation, per device auto-sensing and two forms of auto-uplink, the WS-C3750-48PS-S Cisco 3750 switch implements unique Cisco flow control algorithms. At face value, these are already some of the best data flow regulation algorithms on the planet, but upon closer examination, you’ll realize that they also give you the ability to step in and take control yourself. Using Trivial File Transfer or any of nine remote management protocols to make changes, you can determine just how bandwidth gets allocated. Of course, you can also use the Access Control Lists to completely shut certain devices out, increasing your network’s overall security.
IPv6 support and the ability to track over 12K of individual MAC addresses lets you connect old and new devices seamlessly. For fast network backbone communication, the WS-C3750-48PS-S Cisco 3750 series switch uses four SFP mini-GBIC connectors capable of super high-speed transmissions. You don’t have to worry about slowdowns on the 10/100 side either because the ports have full duplex capability and layer 3 switching helps optimize transfers.
With 128 MB of RAM and 16 MB of dedicated Flash Memory, the refurbished WS-C3750-48PS-S is more than just your typical bare bones switch. Log data and settings can be stored until you’re ready to collect and analyze them, meaning that you’ll always know just what’s going on in the span of this device’s 166,408-hour mean time between failures.
