Additional Advisory Data
Solutions
CNA: Eppendorf has released a software update that permanently removes VNC access from the controller. Users should download and apply this update from: https://www.eppendorf.com/software-downloads. https://www.eppendorf.com/software-downloads All affected BioFlo 320 systems always shipped with Virtual Network Computing (VNC) disabled by default, and VNC can only be enabled locally at the tower. Eppendorf has removed VNC configuration information from all current documentation, so it no longer appears in BioFlo 320 Operating Manuals. Eppendorf recommends user do the following: - Verify that VNC is disabled on the controller - Enable security so that only Admin and Supervisor roles can change VNC settings - Install Version 5.0 Software as soon as possible
