Run the following command to read the module's EEPROM information from the A0 register area: show fiber-ports optics-eeprom <slot/port>Run the following command to read the module's EEPROM information from the A0 register area: show fiber-ports optics-eeprom <slot/port>You can use the display commands to view information about the optical module on an interface, including conventional information, manufacturing information, and alarm information about the optical module. When the optical module on an interface is faulty, you can run the following command to view. These modules play a crucial role in establishing high-quality links that are zero-packet-loss, non-blocking, and low-error. The installation, removal, replacement, and maintenance of optical modules affect the overall link quality. ) ships with a small EEPROM that stores two kinds of information: a fixed Serial-ID block (vendor, part number, serial number, capabilities) and—when provided—a diagnostics area (real-time temperature, voltage, TX/RX power, etc. This is used to support the basic GBIC requirements and the extended SFF-8472 requirements at the first 2-wire address (by default address A2 is handled by the.
