PowerConnect 5316M Ethernet Switch Module
The PowerConnect 5316M Ethernet switch module is a 16-port switch with 6 uplinks and 10 downlinks (see Figure 2 -12 ). The uplinks connect to the external
Ethernet network and operate at 10/100/1000 Mb. The downlinks connect to the embedded Ethernet controller on the server module and operate at 1000 Mb
only.
The PowerConnect 5316M Ethernet switch module is hot-pluggable. To provide connectivity into separate Ethernet networks, two switch modules can be
installed in bays I/O 1 and I/O 2 (see
Figure 2 -5 ). I/O bays 3 and 4 require that you install a Gb Ethernet daughter card in the server module. If redundancy is
not required, the switch module must be installed in I/O 1 bay. The switch module has an internal serial port that communicates with the DRAC/MC module.
Table 2 -11 lists the indicators on each switch module. For additional information about the PowerConnect 5316M Ethernet switch module, see the
documentation that shipped with the module.

Fibre Channel Pass-Through Module
The Fibre Channel pass-through module provides a bypass connection between the Fibre Channel daughter card in the server module and optical transceivers
for direct connection into a Fibre Channel switch or a storage array. (see
Figure 2 -13 ). The Fibre Channel pass-through modules are hot-pluggable. The Fibre
Channel pass-through module in I/O bay 3 connects to port 1 on the optional Fibre Channel daughter card installed in a server module. The Fibre Channel
pass-through module in I/O bay 4 connects to port 2 on the optional Fibre Channel daughter card installed in a server module. To provide redundancy, both
I/O bay 3 and I/O bay 4 must have Fibre Channel pass-through modules installed.
Table 2 -12 lists the functionality of the Fibre Channel pass-through module
indicators. For additional information on installing this module, see " Chassis I/O Module " in "Installing System Options."
