LEDs
Note |
The Cisco NCS 540 Router LEDs are similar for most of the variants, and any differences between the routers are specifically called out. |
Router LEDs
All the data port LEDs in the Cisco NCS 540 Router are at the front panel. There are five LEDs that reflect the different statuses of the system.
