Cisco ASR 903 is a powerful router that provides high-performance connectivity and services for enterprise and service provider networks. One of the primary concerns for network administrators is the number of power slots available in this router. In this article, we will discuss in detail how many power slots are available in Cisco ASR 903.
Firstly, it is important to understand that Cisco ASR 903 comes in two different models: ASR-903 and ASR-903-R. The ASR-903 model has a single power supply slot, whereas the ASR-903-R model has two power supply slots.

The single power supply slot in the ASR-903 model supports a single AC or DC power supply module. This module can provide up to 2500 watts of power, which is sufficient to run the router and its associated modules.
On the other hand, the two power supply slots in the ASR-903-R model support a redundant configuration, where two AC or DC power supply modules can be installed for redundancy purposes. This means that if one of the power supplies fails, the other one will take over seamlessly without any disruption to network operations.
In terms of physical appearance, both models have identical chassis dimensions and form factors. The only difference is that the ASR-903-R model has an extra slot for the second power supply module.
It is also worth noting that Cisco offers different types of power supply modules for both models. These modules have different output capacities and efficiencies, so it is important to choose the right one based on your specific requirements.
To summarize, the number of power slots in Cisco ASR 903 depends on whether you have an ASR-903 or an ASR-903-R model. The former has a single power supply slot, whereas the latter has two slots for redundant configurations. Both models support AC or DC power supplies with varying output capacities and efficiencies.
In conclusion, having a clear understanding of the power slots available in Cisco ASR 903 is crucial for network administrators who want to ensure reliable and uninterrupted network operations. With the right power supply module and configuration, you can rest assured that your network will run smoothly and efficiently.
