Dell has been selling Cisco equipment through its direct online sales channel for several years. It currently offers all of Cisco's products for large enterprises and some of its products for small and medium-sized businesses.
From 27 September most Dell customers will not be able to purchase Cisco gear through the company. Exceptions will be made until 31 October for some customers that are considered critical by either company, a Dell spokeswoman said.
Dell sells a growing line-up of its own network switches under the PowerConnect badge. It also has preferred provider relationships with three other network equipment makers - Nortel, Extreme Networks and Enterasys Networks - and also sells systems from other manufacturers.
"Between the Dell PowerConnect switches and the switches from our preferred providers, there should be no problem for our customers to get what they want," a Dell representative said.
