Summary: Case# 03434266 I called Linksys to get my switch RMA'd and all went well untill the RMA department. RMA rep told me that Linksys no longer supports the Linksys SD2008 and Cisco takes care of it. I called Cisco up and explained the situation which ended up being transfered to Linksys Small Business and that they also no longer support the SD2008 since sometime in 2011. So much for Limited Lifetime after only 5 years of service and one RMA already in.
Excerpt: I never like this device. The SD2008 specifically version 2.1 is piece of hardware that keeps on malfunctioning. I had like five calls received from different customers who own multiple unmanaged switch like these from Linksys.
Good performance but it became intermittent and finally kicked the bucket after 6 years!
7 August 2014
Summary: I have several of these and the one that is about 6 years old just failed. It was becoming intermittent and with a big network it is hard to find the one component that is acting up. Finally today it just died so I could identify the bad component in the system which was this switch. This type of equipment should last for 10 years. It is plugged into a UPS backup system that is surge protected and there is no reason for it to fail. This is the highly touted version 3.
Summary: We've purchased 4 of these switches for our Cat 5e gigabit Ethernet house... and they have ALL failed after only 2 years! First indication is one or more ports suddenly not working. Yes, Linksys (now Cisco) fortunately provides a lifetime warranty and its a good thing since they've ALL gone bad at least once.
Summary: I purchased this unit for a remote area of our offices to replace an older 100Base-T unit. It slowed the area to a crawl. Testing showed that traffic was flowing at 1/3 the speed of the old unit. I have been trying for the last week to return the unit, but PC universe does not reply to email and calls just go to a "mailbox full" message. Fulfillment of the order was good, but customer service is NON-EXISTANT.
Summary: Signifiant changes have occurred over the life of this switch. Version 1 had an internal fan and was quite noisy, albeit cool running. Version 2 & 2.1 eliminated the fan. However capacitor C251, sitting next to an internal heatsink is prone to failure after 6 - 8 months, resulting in dropped packets and link connections. Version 3.0 has solved this problem with a complete re-layout of the printed circuit board (PCB), with a redesign of the power/voltage regulation.
Summary: I own two of these, version 2.1 and version 3.0. Version 2.1 definitely runs too hot but after 2 years of being on 24/7 it is still going strong. Version 3.0 runs cooler and the performance on both is outstanding. I have 5 servers and 4 workstations in a lab setting, moving 40-60 GB files between them often, throughput is excellent with transfer rates upto 40-50 MB/Sec, so a 60 GB file transfers in about 20 min.
Summary: This excellent Ethernet Switch fully lives up to any expectations related to its prestigious manufacturer. Metal body: heavy, solid, durable-looking. Setup time: zero. Problems/bugs: zero. All three PCs having Gigabit capability in my home network immediately recognized the new 1GB bandwidth limit. And of course moving large files between them is now a lot faster.
Summary: Version v3 fixes the well known problems of v1 - noisy fan, no jumbo frame support. Also fixes v2.X issue of overheating. The SD2008 has gotten some justifiably bad reviews based on the earlier v1 & v2.x designs. I had a SD2005 (the 5-port version of the SD2008) v2 suddenly fail (no link on any ports) after 1 year, and Cisco issued an RMA and sent me a new SD2005 v3 switch, and I've had no problems with it.
