Ethernet Switches or Hubs
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.
