Patent ID: 7953109

Claim:
An input/output section comprising: (a) a transmit protocol translation section for translating a protocol used by user data passing from a bank of disk drives to a processor to a protocol used by the user data passing from the processor to the host computer or server, such transmit protocol translation section having a data port coupled to a data port of the processor and a transmit signal port for producing a transmit control signal; (b) a data transceiver having: an data transmitter enable/disable terminal; and a data terminal for receiving the user data from the transmit protocol translation section and for optically transmitting the user data from the processor through the transmit protocol translation section and then to the host computer or server in response to a transmit enable signal fed to the data transmitter enable/disable terminal and for inhibiting the user data from the processor from the passing from the transmit protocol translation section and then to the host computer or server in response to a transmit disable signal fed to the data transmitter enable/disable terminal; (c) a gate for producing the transmit disable signal at the data transmitter enable/disable terminal of the transceiver in response to the transmit disable signal at the enable/disable signal port of the processor independent of the transmit control signal at the transmit signal port of the protocol translation section.
