This Redundant Power Array Cabinet accessories provide optional redundant power options to a range of Allied Telesis switches. Installing a redundant power supply increases network reliability, as the switch can continue to operate in the event of a failure of the switch's main internal power supply, or that of the redundant power supply. Failure of either power supply causes an event to be sent to a Network Management System (NMS) allowing a network administrator to take the appropriate remedial action, thus averting a catastrophic failure on the network. This cabinet thus increasing system reliability on multi-switch installations. Additionally, each power supply can be individually isolated, to help in both installation and troubleshooting.
