Ethernet Switches or Hubs

Each Ethernet switch or hub you plan to install requires an AC power source. For

information about the use of Ethernet switches or hubs, refer to Section 11, Planning

for LAN Communications.

System Enclosures

Auto-ranging power supplies in the PMF CRUs and IOMF CRUs automatically

configure themselves for either 100-120 V AC or 200-240 V AC operation upon

application of AC power. In system enclosures without power shelves, the power

supplies are within the PMF CRUs and IOMF CRUs. In system enclosures with power

shelves, the power supplies are independent CRUs contained in the power shelf.

For the power requirements for a system enclosure, refer to AC Power Requirements

for One System Enclosure on page B-11.

IOAM Enclosures

For the power requirements for an IOAM enclosure, refer to Appendix G, Modular

Power Information.

Peripheral Devices

Tape drives and other peripheral devices installed outside of system enclosures must

each have a dedicated branch circuit. Different devices have their own power

requirements. Refer to the documentation for the peripheral device for power and other

site planning information.

If a tape drive is connected to the SCSI port of a PMF CRU, you must use a specific

cable to connect the tape drive to the PMF CRU. For available cables, refer to Cables

and Cable Assemblies on page A-26.

AC Power Cords

Each system enclosure requires two AC power cords. The types of AC power cords

vary by country, enclosure type, and voltage required; for the AC power cords that are

appropriate for your system, refer to AC Power Cords, Enclosures Without Power

Shelves on page A-29 and AC Power Cords, Enclosures With Power Shelves on

page A-30.
