Verifier/Certifier as long as it works. - 08/26/11 08:43 PM
Today I had an issue with a number of pcs in a new medical office. The ip guy called me to say he was losing network conectivity with some of his pcs. I went to the site and tested the cables and network ports with my RWC. It told me that my cables all passed for gigabit speed but that there was a problem negotiating with the Dell managed gig switches. After a call to Dell support, the solution turned out to be a setting on both ends, a nic option as well as a switch option. We had to turn IEEE settings off. This is the energy efficient ethernet option which turns the nic and the switch port off after a time of inactivity. This causes the connection to drop and a problem with auto negotiation when the pc tries to reconnect. My inexpensive certifier saved me a lot of time by pointing me in the right direction.
