This invention provides another optical path fault recovery method by which when the resources of a standby path are used by extra traffic, the standby path can be set quickly and an active path can be switched to the standby path without any improper connection in the event of a fault on the active path. An end point node of a path having received fault notification issues a resource securing request message transferred hop by hop to a start point node along the standby path. In the case where resources of the standby path are secured, when the resources are used by the extra traffic, the nodes on the standby path and the start point node that have received the message release the extra traffic and then secure the resources. When the resource securing request message reaches the start point node, the start point node issues a switch changeover request message, and the end point node, the start point node, and the nodes on the standby path set switches according to the secured resources.

A reagent supply arrangement for a hemodialysis system may include an E-prong connector having three parallel prongs with two outer prongs arranged in a common plane and a center prong arranged above the common plane, a first supply line for a first reagent connected in fluid communication with one of the outer prongs, a second supply line for a second reagent connected in fluid communication with the other of the outer prongs, a liquid line connected in fluid communication with the center prong, and a container for housing the first reagent having an inlet connected to the liquid line and an outlet connected to the first supply line for the first reagent.
