I/O Modules
The EMG module port configuration can be changed by adding or replacing I/O modules in the I/O
module bays. Any changes to the I/O modules must be done while the unit is powered off. The
following I/O module configurations are supported (Bay 1 is the leftmost bay when viewing the
front of the EMG where the device ports are located):
Table 10-1 Supported I/O Module Configurations
The number of device ports in the EMG can be expanded by adding a 4-port I/O module in Bay 2.
The configurations listed above are the only valid configurations; if any other configuration is
detected at boot, the EMG unit will still boot, disable use of the device ports, and provide
indications in the boot messages, in the CLI and in the web that the I/O configuration is invalid.
When an invalid configuration is corrected by reconfiguring the I/O modules into a valid
configuration, after the EMG module is powered up and booted, the valid configuration will be
detected and the EMG module ports can be used again.
See
Figure 10-2 Devices > Device Status on page 184
.
Device ports in slot 1 are numbered 1-4 and device ports in slot 2 are numbered 5-8, even if slot 1
is empty.
Restoring Configurations
Restoring a configuration to the EMG will automatically adjust the number of device ports to reflect
the number of ports in the EMG unit the configuration is being restored to.
