Cisco Secondary Power Supplies: Ensuring High Availability in Network Infrastructure

Cisco Secondary Power Supplies: Ensuring High Availability in Network Infrastructure

In today’s interconnected world, a steadfast network infrastructure is indispensable to the vitality of any enterprise. With the ever-increasing demands for uninterrupted connectivity organizations cannot deal with downtime. While the importance of robust routers, switches, and other networking devices is evident, one critical component often remains in the shadows: the power supply system. Cisco, a global leader in networking offers an impressive range of secondary power supplies to maintain network resilience.
