Cisco IRM 1100 4A2T, Gigabit Ethernet, 1000 Mbit/s
The IRM 1100 4A2T is an expansion module that can be attached to the IR1101. It offers an additional four asynchronous serial ports and two Ethernet interfaces to the IR1101.
The IRM 1100 4A2T Ethernet interfaces are Layer 2 RJ45 10/100/1000 Mbps ports.
The IRM 1100 4A2T serial ports are RJ45 combo ports (RS232/RS485/RS422).
The IR1101 has two sides that expansion modules mount to. The top is called the Expansion side, and the bottom is called the Compute side. If the additional module is connected to the top, then it is referenced as the Expansion Module (EM) side. If the additional module is connected on the bottom, then it is referenced as the Compute Module (CM) side. Functionality differs depending on which side the expansion module is attached to, and how many and type of expansion modules are in use.
