4.7 Ethernet Ports
4.7.1 Ports
• 2 fully routed Ethernet IEEE 802.3 LAN interfaces with two optional SFP slots for
the SDM-9140e, each of which can accept a 1000Base-LX Ethernet optical SFP
or a 1000Base-T RJ-45 electrical SFP.
• 6 additional Ethernet ports for the SDM-9140e connected through an integrated
LAN switch.
• RJ-45 10/100 Base-T connectors and 1000 Base-T (for the SDM-9140).
• Each port can be configured with 6 IP addresses, providing a maximum of 12 IP
addresses per unit.
• Auto-detect speed, 10 or 100 Mbps or 1000 Mbps (for the SDM-9140).
• Frame types: Ethernet II, IEEE 802.2, 802.3, SNAP.
• Ethernet interface: Ethernet II and IEEE 802.2, 802.3.
• Standards: IP RIP V1/V2 or Static, OSPF, NAT, IP Multicast IGMP V1/V2 PIM-
DM, BOOTP/DHCP Relay, DHCP client, IPX RIP and SAP, LLC2, 802.1p/q
prioritization and VLAN, 802.1D Spanning Tree Protocol (STP), MAC Layer.
• Filter Criteria: Based on protocol, address (source, destination or SAP) or custom
filtering.

page 3-39.
4.7.2 LAN Status LEDs
For the SDM-9120/9220/9230 units, two pairs of LAN status indicators are located below
the Ethernet ports on the rear panel of the chassis (refer to “Rear View of the SDM-9220/
9230 UAC” on page 4-5). The LEDs for Ethernet port 1 are located on the left, and the
LEDS for Ethernet port 2 are located on the right.
These LEDs indicate the following:
•LINK: Goes on when the corresponding LAN connection passes the Link
Integrity 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).
For the SDM-9140, two LEDS are embedded in each RJ-45 Ethernet connector (refer to
“Front View of the SDM-9140e” on page 4-7).
The Ethernet Port link is up when the Left LED is on. The LEDs indicate the following:
