Reducing power consumption of electronics

One of our network switches stopped working.  While looking for replacements, I decided to look for a switch that would be more energy-efficient than the existing one.  I was very interested in D-Link's Green line of products. I bought the DSG-1024D 24-port network switch.  I figured that I would be able to replace several switches with a single energy-efficient switch.

The D-Link Green series has several ways that it saves power:

  • It powers down port where it detects an idle link status.

  • The switch can detect the cable length of Gigabit Ethernet run, and will use less power for shorter runs.

Before I replaced the switch, I measured the combined energy usages of the switches and did the same after replacing the old ones with the new switch.  By just replacing the two older switches, with the single new switch I saw some power savings.  Since I have other switches that are always on, I decided to replace those as well.

Once I replaced these switches, I saw a savings of 8 watts.

Setting up D-Link DAP-2553

Our Airport base stations were starting to die.  Every once in a while, the basestations would still broadcast the SSID, and wireless devices could still connect to them but wouldn't transmit any data to our wired network.  Since this was happening to both our Airport Express and Airport Extreme base stations, I assume that there was something, either on the wired network, or some RF interference that was causing them to lock up.

I took this opportunity to upgrade to a 802.11n base station, so I bought the D-Link DAP-2553.  This was one of the few dual-band, non-router, base stations.  Once I set it up,  things have been working a lot better than they were with the Apple base stations.
