4.5.2 LAN Status LEDs
Two pairs of LAN status indicators are located below the Ethernet ports on the rear panel
of the SDM-9220/9230 chassis (refer to “Rear View of the SDM-9230 UAC” on page 4-
3). The LEDs for Ethernet port 1 are located on the left, and those for Ethernet port 2 are
on the right.
These LEDs indicate the following:
• LINK: Goes on when the corresponding LAN connection passes the Link Integ-
rity test. In addition, the LED color indicates the LAN speed:
- Amber: Link integrity at 100 Mbps
- Green: Link integrity at 10 Mbps
- Off: No link integrity signal detected.
•
ACT: Goes on (green) when there is activity on the corresponding LAN port
(LAN traffic transmitted or received).
