The TwinBlade 1-Gigabit Ethernet Pass-through Module (part ID SBM-GEP-T20) is a non-configurable pass- through module that includes twenty 1-Gb/s external uplink (RJ45) ports and twenty internal 1-Gb/s downlink ports for the TwinBlade's LAN interfaces. This module also has an internal I2C path to the CMM for viewing module temperature and voltage (but not for configuration since all connections are fixed).
