Cisco NCS 540 Large Density Routers Overview
Each alarm input can be provisioned as critical, major, or minor.
Console
The RS232 console port, connected through RJ-45 jack at rear panel, provides transmission (Tx), reception
(Rx), and ground (Gnd).
USB Console
A single USB 2.0 and 3.0 Type-A receptacle on the front panel of the router provides console access to Cisco
IOS XR, and diagnostics. While it uses the Type-A connector, it operates as a USB peripheral only for

Type-A to Type-A USB cable.
