5-4 SBM-GEM-002 1-Gb Ethernet Pass-through Module
The SBM-GEM-002 Gigabit pass-through module is a non-configurable pass through
module that includes fourteen (14) 1-Gb/s uplink (RJ45) ports and fourteen 1-Gb/s
downlink ports for the SuperBlade's LAN interfaces. This Ethernet module has two
internal Ethernet paths to the CMM(s). The switch 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 14 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 5-4 , Table 5-10 and Table 5-11 for switch details.

NOTE: The SBM-GEM-002 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.
