I/O Module (IOM)
I/O Module (IOM) is a hardware platform card with ports that provides the following functions:
l Receive data
l Fast forward data
l Transfer data to SSM, QSM, or SWM (only SG-6000-X10800, and SG-6000-X9180 support
the SWM module) modules.
The device should have at least one IOM installed and you can install more to increase the port
amount. IOM should be installed in general expansion slots.
Service and IO Module (SIOM)
Service and IO Module (SIOM) is a hardware platform card with ports that provides the following
functions:
l Receive data
l Fast forward data
l Transfer data and process data traffic
You can install more than one SIOM modules to escalate system performance and increase the
port amount. SIOM should be installed in general expansion slots.
Switch Module(SWM)
Switch Module (SWM) is a hardware platform card that connects the general expansion slots of
the front panel to forward the data. Only SG-6000-X10800, and SG-6000-X9180 support the
SWM module.
The device must have at least one SWM installed. You can install a second SWM for redundancy.
SWM can only be installed in the SWM0 and SWM1 slots of the back panel. If the device has two
SWMs installed, they work in the redundancy mode in which the backup module takes over the
master module’s work when the master module fails.
