Cisco router has several types of ports and interfaces to interconnect many other devices and other routers. For this reason, these devices have many types of ports and interfaces. Figure 1 illustrates the back panel of Cisco router 1941. Here is the short explanation of back panel of the Cisco router 1941.
Back Panel Explanation of Cisco Router 1941
- These are 2 USB ports providing extra storage space similar to flash. These ports are also labeled as USB 0 and USB 1.
- These are Gigabit Ethernet interfaces. These ports generally provide LAN access by connecting to switches, other routers, and users. The ports label is GE0/0 and GE0/1.
- These ports are Auxiliary (AUX) RJ-45 ports. Auxiliary ports are being used for remote management access similar to the Console port. Now considered a legacy port because of providing support for dial-up modems.
- These are console ports of the router which is important for the initial configuration of the router. Two ports are available; the commonly used regular RJ-45 port at the left and a new USB Type-B (mini-B USB) connector at the right side at number 4. However, the console can access by one port at a time.
- Enhanced High-speed WAN Interface Card (eHWIC)- This slot labeled as eHWIC 0 and eHWIC 1. These ports provide modularity and flexibility by enabling the router to support different types of interface modules, including serial, digital subscriber line (DSL), switch port, and wireless.
- Compact Flash slots labeled as CF0 and CF1 to provide increased storage flash space upgradable to 4 GB compact flash card per slot. By default, CF0 populated with a 256 MB compact flash card and is the default boot location.
