WAN interfaces: four GE electrical interfaces NOTE:
GE9 is a management interface and is used to upgrade the router. |
10 |
LAN interfaces: eight GE electrical interfaces NOTE:
All GE LAN interfaces can be configured as WAN interfaces. |
11 |
AC power jack NOTE:
Use an AC power cable to connect the router to an external power source. |
12 |
Jack for power cable locking strap NOTE:
Insert a power cable locking strap in this jack to secure the power cable. |
Slot Distribution
- Two SIC slots can be combined into one WSIC slot by removing the guide rail between them.
- After two slots are combined into one, the new slot ID is the larger one between the two original slot IDs.
Figure 4-148 shows the slot distribution of the AR1220-8GE router.
- Slot 1 and slot 2 can be combined into new slot 2.
