Management Interface Pins Sample Clauses

Management Interface Pins. The CFP8 Module supports alarm, control and monitor functions via an MDIO bus. Upon module initialization, these functions are available. The CFP8 MDIO electrical interface consists of four pins including 2pins for MDC and MDIO, the Module Select pin and the Global Alarm pin. MDC is the MDIO Clock line driven by the host and MDIO is the bidirectional data line driven by both the host and module depending upon the data direction. The CFP8 MDIO pins are listed in Table 2-3. Specifications of the CFP8 hardware management interface pins are given in Ref. [2] with the following changes listed below. Table 2-3: Management Interface Pins (MDIO) Pin # Symbol Description I/O Logic ³+ ³/ Pull-up /down 89 GLB_ALRMn Global Alarm O 3.3V LVCMOS OK Alarm 92 MDC MDIO Clock I 1.2V LVCMOS 91 MDIO Management Data Input Output Bi-Directional Data I/O 1.2V LVCMOS 90 MOD_SELn Module Select I 3.3V LVCMOS De- select Select Pull-Up3 3 Pull-Up resistor (4.7 kOhm to 10 kOhm) is located within the CFP8 module For CFP8, the MOD_SELn pin replaces the PRTADR pins used on CFP/CFP2/CFP4. The MOD_SELn pin is used in cases where a single MDIO bus is shared between more than one CFP8 module.

Management Interface Pins. The CFP2 Module supports alarm, control and monitor functions via an MDIO bus. Upon module initialization, these functions are available. CFP2 MDIO electrical interface consists of six (6) pins including two (2) pins for MDC and MDIO, three (3) Physical Port Address pins, and the Global Alarm pin. MDC is the MDIO Clock line driven by the host and MDIO is the bidirectional data line driven by both the host and module depending upon the data directions. The CFP2 MDIO pins are listed in Table 2-4. Specifications of the CFP2 hardware management interface pins are given in Reference [1] with the following changes listed below.

Management Interface Pins. The CFP4 Module supports alarm, control and monitor functions via an MDIO bus. Upon module initialization, these functions are available. CFP4 MDIO electrical interface consists of 6pins including 2pins for MDC and MDIO, 3 Physical Port Address pins and th Global Alarm pin. MDC is the MDIO Clock line driven by the host and MDIO is the bidirectional data line driven by both the host and module depending upon the data directions. The CFP4 MDIO pins are listed in Table 1-3. Specifications of the CFP4 hardware management interface pins are given in Ref.[2] with the following changes listed below.
