• Ethernet management port. See

• RJ-45 console port (EIA/TIA-232). See

• USB mini-Type B console port (5-pin connector).

The 10/100/1000 Ethernet management port connection uses a standard RJ-45 crossover or straight-through

cable. The RJ-45 console port connection uses the supplied RJ-45-to-DB-9 female cable. The USB console

port connection uses a USB Type A to 5-pin mini-Type B cable. The USB console interface speeds are the

same as the RJ-45 console interface speeds.
