The Netgear GSM7352S 48 port switches are a nifty little unit from Netgear. Layer 3 and Layer 2 capable, these switches (the -100 version) are the original release without dual removable internal power supplies. (these have the single internal power supply with a redundant external power supply connector where you can attach the alternate power supply. They run about 10C hotter than their equivalent 24 port counterpart (due to higher component count, increased heat sinks for the components, and for whatever reason they wrap the power supply with flame retardent cardboard. which blocks 60% of the intake airflow on the left hand side.. Guaranteed for life by the manufacture, these little guys are work horses for those unwilling to shell out the big bucks for Cisco equivalents. Stackable with 10 gig (fiber), or 24 gig stacking modules (using thumbscrew infiniband cabling) these units provide the ability to manage up to 8 switches as a single unit. Web Gui's decent. Command line is somewhat tolerable.. 4 10G+ ports are extremely flexible.. 8 multifunctions are superb for long haul fiber interconnects.. a bit too noisy for small office use (most racked gear is "noisy". we use these extensively throughout our blade server infrastructure to interconnect the management and sans (when not using FC or infiniband) and have very little issue with the units (we regularly use 9000 MTU's for virtual system imaging transfers). We've had other manufactures buckle under the consistent load but these switches deliver: highly available, fault tolerent, and ease of stack management in a 1u package. The lifetime guarantee just helps you sleep at night knowing they will replace them as needed. annual service contract on a single switch with same day replace runs us approximately $69 a switch per year.. and thats without a quantity discount. A great data center building block for the budget minded.Read full review
