Usage Features
Installation Flexibility:
- The device can be installed in both IEC 19-inch and ETSI 21-inch cabinets, with specific instructions for each type, including configurations with front columns and middle columns.
- DC and AC chassis are installed similarly, with the DC chassis used as a primary example in the guide.
Component Installation:
- Detailed steps are provided for installing interface boards and main control boards, including handling ejector levers and captive screws.
- Optical modules are installed by inserting them fully into the optical port, followed by connecting optical fibers.
Cable Management:
- The guide emphasizes proper cable routing to prevent blocking air vents and ensure heat dissipation.
- Temporary and formal labels are recommended for cables.
- Specific routing guidelines are provided for different cable types (power, E1, optical fiber, Ethernet) and their placement within the cabinet (e.g., left side for power module maintenance).
- Instructions for handling corrugated pipes for optical fibers are included, specifying length and capacity recommendations.
Safety and ESD Protection:

- Caution against laser beams and direct eye exposure to optical modules/fibers.
- Guidelines for handling chassis to prevent damage during transport and installation (e.g., moving upright, not dragging).
- Instructions for handling cards and modules, including not opening ESD bags until delivery to the equipment room and avoiding using connectors to support card weight.
Maintenance Features
Pre-Power-on Checks:
- Before powering on the device, users must verify the installation of fixed optical attenuators, check the fuse capacity of the external power supply, and confirm normal external power supply voltage.
Power-on Check and Troubleshooting:
- A table describes the expected states of indicators (PWR, FAN, STAT, PROG, L/A) for power modules, fan modules, main control boards, and interface boards when the device is operating properly (steady green).
- Troubleshooting procedures are provided for abnormal indicator states, such as steady red (signals lost on optical port) or steady off (module not detected). These procedures include checking peer chassis/boards, fiber connections, optical attenuators, cleaning fiber connectors, and replacing damaged fibers or boards.
Optical Fiber Maintenance:
