AT-iMG746MOD Installation Guide Chapter 5 Turn-Up and Troubleshooting Turn-up Sequence The AT-iMG7x6MOD is shipped with main software image and a recovery software image, which is used when the main image is corrupted during download. These files are used during turn-up or may be replaced, depending on the DHCP provisioning sequence. Since the initial provisioning of the AT-iMG7x6MOD is done using DHCP, the user must ensure that the DHCP configuration has been set up correctly.

AT-iMG646MOD Installation Guide Power Cord Wiring To wire the terminal block for the gateway to the terminal block for the power supply cord, refer to Figure 32 and Table 5. iMG Terminal Block Power Supply Terminal Block Figure 32. Gateway Terminal Block to Power Cord Terminal Block Wiring Diagram Table 5.
Appendix A: Technical Specifications Serial Port Wiring The CONSOLE port is an RJ45 connection (not a DB9 connection used with other Allied Telesis products). Pinout is as follows. Note When looking at the RJ-45 port, pin 1 is on the right.
Appendix B Cleaning Fiber Optic Connectors The fiber optic connector consists of a fiber optic plug and its adapter. The end of the fiber optic cable is held in the core of the ferrule in the plug. Light signals are transmitted through the core of the fiber. Even minor smudges or dirt on the end face of the fiber, completely invisible to the naked eye, can disrupt light transmission and lead to failure of the component or of the entire system.
Appendix B: Cleaning Fiber Optic Connectors Using a Cartridge-Type Cleaner Fiber optic cartridge cleaners are available from many vendors and are typically called “cartridge cleaners,” as shown in Figure 35. Figure 35. Cartridge Cleaner Note Do not use compressed air or aerosol air to clean a fiber optic connector. To clean a fiber optic connector using a cartridge cleaner, perform the following procedure. 7.
AT-iMG646MOD Installation Guide Note Rub the ferrule tip on the cleaning surface in one direction only. 9. When you reach the end of the cleaning surface, pick up the ferrule tip, rotate and place it at the top and rub downwards at least 2 times. Caution Failing to pick up the ferrule tip when you reach the bottom of the cleaning surface can result in static electricity that can damage the fiber optic cable. 10. If desired, repeat steps 3 and 4. 11.
Appendix B: Cleaning Fiber Optic Connectors Using a Swab Specially treated swabs (stick cleaners) are available for cleaning inside connector adapters or hard-to-reach ferrule tips. These swabs, often referred to as “lint free” or “alcohol free” swabs, are available from many vendors, as shown in Figure 37. Stick cleaners are available in both 2.5 mm and 1.25 mm sizes for use on SC and MU connectors respectively. Note NEVER use a household cotton swab and/or alcohol to clean a fiber optic connector.
AT-iMG646MOD Installation Guide 2. If desired, repeat step 1. 3. If a fiber inspection scope is available, use the scope to inspect the connector to make sure that it is clean and to check for scratches, pits, or other problems that may affect performance. Note Always keep a dust cap on a fiber optic cable when it is not in use. Note Do not touch the end face of the ferrule in the connector. Warning: Do not stare into the laser beam.
