Juniper CB-M-S-B, Control Board (CB) for the M320.

The Juniper CB-M-S-B is a Control Board (CB) for the Juniper M320 router. The CB provides the control and monitoring functions of the M320 and hosts the Routing Engine. The -B suffix is the hardware revision of the board.

It is a field-replaceable unit, supplied as a spare or as a replacement for a failed control board in an existing M320 chassis. Tech-Star (UK-based, shipped worldwide) stocks Juniper control, switch fabric and interface boards for M-series, T-series and MX-series routers. Send us your chassis model and current board revision and we will check the fit before you order. Boards and cards are chassis-specific, so quote the part number printed on the unit when you enquire.
