Nokia C111825.A2A ESB Series Switch / Carrier Ethernet Line Card

The Nokia C111825.A2A is an ESB24-D (Ethernet Switch for B-series, 24-port), an internal Ethernet switching plug-in unit for the Nokia DX200 core-network platform. It provides 24 ports of Ethernet connectivity that carry the internal control and inter-card traffic between the B-series computing cartridges and the other units in a DX200 subrack. As a B-series switch board it supports the packet-based internal messaging used by DX200 network elements such as the BSC and core switching systems. The -D suffix identifies this hardware variant. It installs in the switching position of the equipment cartridge alongside the computer, power and exchange-terminal cards. Tech Star supplies this board as new or refurbished stock for maintaining installed Nokia DX200 systems. Submit a price enquiry for availability and lead time.
