A typical CrossFire M2 system connection is shown in Figure 4.

• CrossFire supports 1 Master A2 and 2 Slave A2
• Cascading up to 5 levels of E2-O
• Cascading up to 6 levels of E2-O + M2RU

Operation and Maintenance Terminal

The Operations and Maintenance Terminal (OMT) software runs on all devices in the CrossFire system. WebOMT is the interface for OMT. WebOMT is based on a web browser and is compatible with most common browsers such as IE and Google Chrome. WebOMT is customized for CrossFire to query, debug, and configure parameters on devices. The Master A2 is generally set as the Host of the system. Meanwhile, technicians can access the whole system through the WebOMT of any device (Master or Slave A2, E2-O, and M2RU) connected in the system.

Access to the OMT on the Master A2

In the CrossFire system, the Master A2 is defined as the Host. The default IP address of the A2 is https://10.7.3.200. To set up wired access to the OMT:

1. Connect a PC to the Master A2 with a network cable in the CONSOLE port on the front panel.
2. Change the TCP/IP properties (see Figure 5):
