This article will outline the Ethernet port speed capability of the aforementioned product lines.


APC Network Management Card 1 and 2 enabled products can be set to one of the following settings in terms of Ethernet port speed:
  • Auto-negotiation
  • 10 Half-Duplex
  • 10 Full-Duplex
  • 100 Half-Duplex
  • 100 Full-Duplex
Speeds are in mbps (megabits per second).

Choosing auto-negotiation will allow the network card to connect to the network at the fastest possible speed available on the network.  If the card has difficulty in negotiating a speed with the network switch, it will choose 10 Half-Duplex.

Note: Connecting the devices mentioned in this knowledgebase  to gigabit/1000mbps network switches may still work. Some switches may support 1000/100mbps and will auto-negotiatiate. They may also the user to specifically force the port to 100mbps but are at least capable of doing so. Other switches support 10/100mbps modules/add-ons for connectivity.
