Technical FAQs 4

What is the difference between N+0 and n+n backup mode?

In the N+N backup mode, N power modules provide power supply, and N power modules act as backups. Even if all the N primary power modules fail, the N redundant power modules can still ensure normal operations of the switch. In the N+0 mode, N power modules provide power supply, and no redundant power module is available.

What happens if a power module fails in n+0 mode?

In the N+0 mode, N power modules provide power supply, and no redundant power module is available. If one power module fails and the total output of the other power modules is smaller than the actual power consumption of the switch, the switch cannot run normally.

How many lbbp boards can be configured in a base station?

The number of LBBP boards to be configured in a base station that supports LTE depends on the number of cells, bandwidths, antenna configurations, and the number of CPRI ports to be supported by the base station. Each BBU working in LTE mode needs to be configured with at least one LBBP and each LBBP supports six RF modules.

How many Boolean alarm inputs can a distributed base station support?

Configured for a distributed base station that needs to support 17 to 32 Boolean alarm inputs or a distributed base station that is supplied with +24 V DC power and needs to support 1 to 16 Boolean alarm inputs. Optional.
