The module signal ground pins, VeeR and VeeT, shall be isolated from the module case. 2. This pin is an open collector/drain output pin and shall be pulled up with 4.7k-10k ohms to Host_Vcc on the host board. Pull ups can be connected to multiple power supplies, however the host board design shall ensure that no module pin has voltage exceeding module VccT/R + 0.5V. 3. This pin is an open collector/drain input pin and shall be pulled up with 4.7k-10k ohms to VccT in the Module. 4. This pin shall be pulled up with 4.7k-10k ohms to Host_Vcc on the host board. 5 Revision: S3 5/30/2013

6. Low Speed Electrical Hardware Pins In addition to the 2-wire serial interface, the SFP+ module has the following low speed pins for control and status: TX_Fault TX_Disable RS0/RS1 MOD_ABS RX_LOS 1 TX_Fault TX_Fault is a module output pin that when High, indicates that the module transmitter has detected a fault condition related to laser operation or safety. The TX_Fault output pin is an open drain/collector and must be pulled p to the Host_Vcc with 4.7k-10k ohms on the host board 2 TX_Disable TX_Disable is a module input pin. When TX_Disable is asserted High or Left open, the SFP+ module transmitter output must be turned off. The TX_DIS pin must be pulled up to VccT in the SFP+ module.. 3 RS0/RS1 RS0 and RS1 are module input rate select pins and are pulled low to VeeT with a > 30kΩ resistor in the module. RS0 is an input hardware pin which optionally selects the optical receive data path rate coverage for an SFP+ module. RS1 is an input hardware pin which optionally selects the optical transmit path data rate coverage for an SFP+ module. 4 MOD_ABS Mod_ABS is pulled up to Host_Vcc with 4.7k-10k ohms on the host board and connected to VeeT or VeeR in the SFP+ module. MOD_ABS is then asserted High when the SFP+ module is physically absent from a host slot. In the SFP MSA (INF8074i) this pin had the same function but is called MOD_DEF0. 5 SCL/SDA SCL is the 2-wire interface clock and SDA is the 2-wire interface data line. SCL and SDA are pulled up to a voltage in the range of 3.14V to 3.46V on the host. 6 RX_LOS RX_LOS when High indicated an optical signal level below that specified in the relevant standard. The RX_LOS pin is an open drain/collector output and must be pulled up to host Vcc with a 4.7k-10k ohms on the host board. RX_LOS assert min and de-assert max are defined in the relevant standard. 6 Revision: S3 5/30/2013
