2.5 LED Display
Signal Name
LED[1:0]
Type Pin No.
O
Description
85, 84
Those signals indicate each port‘s statuses (such as activity, jabber and
partition) and global information(such as Collision , Repeater ID,
Utilization ) in sequence. For detail , see the LED timing specification
The utilization of 100M segment and 10M segment are using the same scale.
The Utilization % display define as following : (See also Note 1)
1: Led off
0: Led on
The buffer utilization of internal switch uses the following definition:
1: Led off
0: Led on
LED[0] : This signal also indicates SRAM chip 0 fail ( continue active low )
and 100M repeater collision ( Blinking ) during the interval of sequence shift
data.
LED[1] : This signal also indicates SRAM chip 1 fail ( continue active low )
and 10 M repeater collision ( Blinking ) during the interval of sequence shift
data.

86
LED Clock :
The signal is a discontinue clock for LED signals serial shift
out. The clock period width is 400nS and last 32 cycle with every 52.4ms
repeated.
