• two DC power supplies
• one AC power supply and one DC power supply
When you operate the switch with two power supplies, the switch supports redundancy, load
sharing, and full hot-swap replacement of a power supply for uninterruptible operation. The
power supply is location independent, you can install an AC or DC power supply into either
power supply slot on the switch.
For cooling, the switch supports two air flow patterns: front to back or back to front. The air
flow direction is determined by the main power supply. All power supplies and fan trays must
match the air flow direction. A switch can operate for a brief period with one fan tray, but one
fan may not be able to achieve maximum environmental conditions.
Each switch is shipped with two fan trays and can support up to two power supplies.
Important:
Power supply and fan tray direction must match. If you require front to back cooling, you
must ensure that the power supply is designated for front to back cooling. Or, if you require
back to front cooling, you must ensure that the power supply is designated for back to front
cooling.
