When you want a monster of a switch with 128 MB of RAM, our refurbished
WS-C3750-48PS-E is right up your alley. Designed for extensive applications with a need for intelligent switching, this full duplex capable Cisco 3750 switch is made with 48 x 10/100 ports for serious connectivity.
Any network you create with this
WS-C3750-48PS-E will be better for it, benefiting from flow control, layer 3 switching and traffic shaping. You can prioritize certain traffic to ensure that it gets guaranteed bandwidth, or you can leave it to the built-in IGMP snooping tool to figure out where to send multicasts and thereby avoid unnecessary loading.
This IEEE-compliant device also relies on Enhanced Image to ensure that any routing it does complies with your protocol preferences. Support for a number of routing protocols including OSPF for IPv6 and policy-based routing make it possible to really get in there and tweak the way your network operates. Of course, built in features like auto-negotiation and auto MDI or MDI-X auto-uplinking take care of the trivial port interactions to ensure that any higher-level routing or authentication methods you choose work as smoothly as possible.
Over 166,000 hours of mean time between failures and a Redundant Power System connector ensure that you can always count on the
WS-C3750-48PS-E to keep on going strong. It also helps that you’ve got four dedicated SFP mini-GBIC connectors at your command so that you can connect to other network nodes with lightning speed.
