The GM-20XT module and GM-20XTR I/O module have 20 autosensing 10/100/1000BASE-T ports that
use standard RJ-45 connectors and 20 SFP mini-GBIC ports.
The default configuration of the GM-20XT and GM-20XTR I/O module is as follows. All ports:
● Are added to the default VLAN as untagged.
● Inherit the properties of the default VLAN (for example, protocol type and VLANid).
● Operate in autonegotiation mode.

Although the XM-2X module and the XM-2XR module are similar in appearance, the functionality of each I/O module
varies. The XM-2XR module is part of the R series and includes the rate limiting feature; the XM-2X module does
not support rate limiting.
To use rate limiting, you must install the MSM-5R plus the GM-20XTR I/O module and/or the XM-2XR I/O module.
