Nortel has announced that it is extending the warranty service on it’s entire line of stackable Ethernet Routing Switches to include next-business-day replacement. This is only available on purchases made after July 1, 2009. Nortel already had a lifetime hardware warranty in place that required you to return any defective units for depot service which would generally take about 10 business days.
There are quite a few vendors now including lifetime hardware replacement on their products although I’m not sure many of them are offering advanced next-business-day replacements.
You can read all about it over at Nortel’s website.
Cheers!
