Power Cord Routing

All modules are shipped with two AC power cords that are appropriate for use in a typical outlet in the destination country. Each power cord connects one of the power supplies in a module to an independent, external power source, such as a wall receptacle or uninterruptible power supply (UPS). If you have a rackmount cabinet with internal power cabling, such as a ladder cable, you do not need these power cords.

Typically, a rackmount cabinet has two AC distribution boxes with two separate power cords (Figure 4-4). To ensure redundancy, each power cord must connect to an independent, external power source. Each AC distribution box has a ladder cable that runs up the inside of the cabinet and connects to one of the power supplies in each unit.

Figure 4-5shows the power cords and receptacles for domestic (inside USA) and international use (outside USA).
