Token Ring Network Modules
Fast Ethernet LEDs
This section describes Fast Ethernet module LEDs.
Figure 3-19
shows 1-port Fast Ethernet network
module LEDs as an example.
Figure 3-19 1-Port Fast Ethernet Network Module LEDs
All network modules have an enable (EN) LED. The enable LED indicates that the module has passed
its self-tests and is available to the router.
Fast Ethernet network modules have the additional LEDs shown in
Table 3-1
.
Token Ring Network Modules
The following network modules provide Token Ring interfaces:
•
1-port Ethernet 1-port Token Ring 2-WAN card slot module (NM-1E1R2W) (see
Figure 3-20
)
•
1-port Fast Ethernet 1-port Token Ring 2-WAN card slot module (NM-1FE2R2W) (see
Figure 3-21
)
