5-5 SBM-GEP-T20 1Gb Ethernet Pass-through Module
for Twin-Blade Modules
The SBM-GEP-T20 Gigabit pass-through module is a non-configurable pass through
module that includes twenty (20) 1-Gb/s uplink (RJ45) ports and twenty (20) 1-Gb/s
downlink ports for the SuperBlade's LAN interfaces. This Ethernet module has an
internal I
2
C path to the CMM. The pass-through module is used to provide a connection
between the Ethernet controller integrated on the mainboard and an external Ethernet
device.
Unlike the SBM-GEM-001 Gigabit Ethernet switch module, this is a pass-through
module and is not configurable. With this module Blade 1 would be connected directly to
port 1, Blade 2 to port 2 and so on. If you are only connected to 10 blades then ports 11
through 20 are not connected.
Temperature and voltage of the pass-through module are read through the CMM
module. The LED’s of the pass-through for a blade are only lit when the blade is on. Like
the SBM-GEM-001 Gigabit Ethernet switch module, this pass-through module is a
hot-pluggable module. See Figure 5-5, Table 5-11 and Table 5-12 for switch details.

NOTE: The SBM-GEP-T20 Gigabit pass-through module must be connected to
another Gigabit Ethernet switch module in order to operate. If you connect it to
a 10/100 switch, it will not work.
