Cable Manufacturing Business’s CMB-16-PMCFC 16-slot EIA-19" Rack-Mount Chassis System provides housing for up to 16 CMB series media converters. Designed for continuous operation, the chassis is equipped with dual cooling fans and redundant power supplies (optional). Its Plug-and-Play and Hot-Swap features allow installing/removing the converter unit without powering off the chassis.
