Chapter 2: Connecting to the Network
The power-up LED sequence for an Ethernet Switch Module not attached
to a network is as follows:
1. All LEDs flash.
2. The PWR LED remains on, and the TX and RX LEDs flash.
3. 3E02-04:
The PROC LED comes on for 5 seconds, then blinks, then remains lit.
The RX, COL, and TX LEDs flash for 100 milliseconds.
3E07-04:
The PROC, RX, and TX LEDs come on for 5 seconds, then the RX and
TX LEDs go off. The PROC LED remains lit.
3E08-04:
The PROC LED comes on for 5 seconds, then blinks, then remains lit.
The RX, COL, and TX LEDs flash for 100 milliseconds.
3E05-04:
The PROC, RX, and TX LEDs come on for 5 seconds, then the RX and
TX LEDs go off. The PROC LED remains lit.
4. After a few seconds the module reboots and the PROC LED comes on.
5. All other LED activity beyond this point is a function of the
configuration and connection of the ATX.

2.3 CONNECTING TO A NETWORK

To connect an Ethernet Switch Module to an Ethernet network, use the
following types of Ethernet cable:
• Unshielded twisted pair (10BASE-T)
• Thin coaxial cabling (10BASE2)
• Multimode fiber optics (10BASE-FL)
• Attachment Unit Interface cabling (10BASE5)
To connect the 3E02-08-ATX to an Ethernet network, use UTP cable
(10BASE-T).
