HP HPE 336045-B21 16 port Dual console KVM switch 396631-001

HP Server Console Switches are key components for rack mount implementations
 (a console represents one keyboard, video monitor, and mouse (KVM) attached to a server).
 The family of HP Server Console Switches allows multiple servers in a rack to be accessed and
 managed by one keyboard, monitor, and mouse. By using a console, as many as 128 computers
 running different operating systems can be managed. Servers can be identified by a user-defined name
 or sequentially by number, enabling easy access to connected servers.
 HP Server Console Switches can be connected in a tiered fashion, to increase server access
 from eight servers to as many as 128 servers. (256 servers if tiering to an HP IP Console Switch)
 Switching between computers is accomplished by typing a switching command at the keyboard,
 or by using the mouse to interact with the graphic interface of the selected computer via the OSD.
