Chapter 5: Installation Installing a NIDU
Installing a NIDU
To install a NIDU (for TDM), use the following procedures:
• Mounting the NIDU on page 5-40
• Connecting the NIDU to the PSU, LAN and TDM cables on page 5-41
• Connecting the NIDU to a DC power supply on page 5-43
Mounting the NIDU
Mount the NIDU in the equipment building, either in a rack or on a horizontal surface:
• Racking mounting option: fix the NIDU to the rack mount using the M3 screws from the
rack mount installation kit (Figure 119). The rack can hold either two NIDUs or one NIDU
and one PTP-SYNC unit.
• Horizontal option: place the NIDU on a horizontal surface.
