Console
The RS232 console port provides transmission (Tx), reception (Rx), and ground (Gnd).
Online Insertion and Removal
The router supports OIR for optical modules, power supplies, and fan modules and trays.
The router supports the following OIR operations:
• When a QSFP is removed, there is no effect on traffic flowing on other ports.
• When a QSFP is installed, the system initializes that port for operation that is based on the current
configuration. If the inserted QSFP is incompatible with the current configuration for that port, the port
does not become operational until the configuration is updated.
• With both power supplies installed and active, the load is shared between them.
When a power supply is removed, not working (failure), or the input cable is removed, the remaining
power supply takes the entire load without disruption.
• There are six fan modules for the NCS 57B1 chassis, and six fan trays for the NCS 57C3-MOD chassis.
Each module or fan tray has two fan units.
