Verifying environmental suitability
The following section describes how to verify environmental suitability for the switch.
About this task
Perform the following procedure to verify environmental suitability before installing the
switch.
Procedure
1. Determine the physical location and placement of the switch.
2. Test and assess the physical location to gather environmental ranges for
temperature, humidity, altitude, and acoustic noise.
3. Verify that the installation environment meets all environmental requirements, see
on page 15.
Power specifications
The VSP 7000 series switches support the following power supply configurations:
• one AC power supply
• one DC power supply
• two AC power supplies
• 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
