Abstract: Described embodiments provide system and methods for selecting a device via which a client is to connect with a server. A client may identify a server and a plurality of devices intermediary to the client and the server via one of which the client is authenticated to connect to access the server using a certificate. The client may detect that the server is unreachable from the client authenticated to use a first connection via a first device of the plurality of devices using the certificate. The client may select, responsive to detecting that the server is unreachable, a second device of the plurality of devices via which the client is to access the server. The client may authenticate, using the certificate used to authenticate with the first device, the client to establish a second connection with the second device to access the server.

Abstract: A high power amplifier may amplify an RF or microwave input signal. The amplifier may include: an input signal divider (DIV) that has an input port for the input signal and that divides this input signal into multiple sub-input signals; multiple power amplifier units (PAUs), each having an input port for receiving one of the sub-input signals and an output port for delivering an amplified version of the received signal; multiple power supply units (PSUs), each connected to power a different one of the PAUs; and an interface control unit (ICU). The ICU may: monitor each PSU to verify that it is operating within one or more pre-determined PSU specifications; and upon detecting that a PSU is no longer operating within the one or more pre-determined PSU specification (malfunctioning PSU), set the PAU being powered by the malfunctioning PSU (online PAU in online mode) not to amplify one of the sub-input signals and not to be available for being switched to the online mode (offline mode of offline PAU).
