Cisco Prisma II XD Chassis network equipment chassis 3U Gray

In optical transmission systems, the network platform forms the foundation of the product family. The Prisma II ™ XD platform provides network operators with a full-featured space saving design. The chassis can be AC or DC powered – the AC chassis uses 2 redundant and load sharing, rear mount power supply modules. DC power can be wired directly to the chassis without the need of a power supply module, and redundant power connections provide power sharing from chassis-to-chassis. Features such as high module density, broad operating temperature range, and a design optimized for easy module insertion, setup, and administration make the Prisma II XD platform a key co mponent in increased network reliability, scalability, and more cost-effective deployments
