Description
Connection on
82564EB
Single Port
Device
LED 0 – Link Up/Activity LED
This corresponds to port 1’s LED#0
from the 631xESB/632xESB.
No-connect
LED 1 – 10 Mbps LED
This corresponds to port 1’s LED#1
from the 631xESB/632xESB.
No-connect
LED 2 – 100 Mbps LED
This corresponds to port 1’s LED#2
from the 631xESB/632xESB.
No-connect
LED 3 – 1000 Mbps LED
This corresponds to port 1’s LED#3
from the 631xESB/632xESB.
No-connect
LED 4 – Full Duplex LED
This LED will light when port 1’s PHY ^No-connect
is operating in Full Duplex Mode
LED 5 – Transmit Activity LED
This LED will light when port 1’s PHY ^No-connect
transmits a packet
LED 6 – Receive Activity LED
This LED will light when port 1’s PHY
receives a packet
This pin also functions as the clock
view pin and will output clock signals
required for IEEE conformance
testing. This pin should have a
stuffing option for a test header.
