Console

Console
The RS232 console port provides transmission (Tx), reception (Rx), and ground (Gnd).

USB Console

A single USB 2.0 Type-A receptacle on the front panel of the router provides console access to uboot, Cisco
IOS-XR and diagnostics. While it uses the Type-A connector, it operates as a USB peripheral only for
connection to an external host computer. This interface requires the use of a Type-A to Type-A connector
instead of a standard USB cable.
Note
Use of the USB console is mutually exclusive of the RS232 console port. This interface requires the use of a
Type-A to Type-A USB cable. If you insert the USB cable and connect to the host computer, then you can
only enter the commands using the USB.

Online Insertion and Removal

The router supports the following Online Insertion and Removal (OIR) operations:
• When an SFP is removed, there is no effect on traffic flowing on other ports.
• When an SFP is installed, the system initializes that port for operation based on the current configuration.
• When both power supplies are installed and active, the load may be shared between them or a single
• Both the power supply modules are fixed and cannot be removed.

Supported Transceiver Modules

If the inserted SFP is incompatible with the current configuration of that port, the port does not become
operational until the configuration is updated.
PSU supports the whole load. When a power supply is not working or the input cable is removed, the
remaining power supply takes the entire load without disruption.
