32 Aruba 8325 Switch Installation and Getting Started Guide
1. Prepare the installation site
Cabling Infrastructure - Ensure the cabling infrastructure meets the necessary network specifications. See
chapter 7, Cabling and technology information for more information:
Installation Location - Before installing the switch, plan its location and orientation relative to other devices and
equipment:
• In the front of the switch, leave at least 3 inches (7.6 cm) of space for the twisted-pair and fiber-optic cabling.
• In the back of the switch, leave at least 3 inches (7.6 cm) of space for the power cord.
• On the sides of the switch, leave at least 3 inches (7.6 cm) for cooling.
Cooling air flow in Aruba 8325 switches is Front-to-Back (FB) or Back-to-Front (BF), depending on which power
supply and fan assembly options are installed. To reverse the cooling air flow direction in an 8325 switch, you must
replace the existing power supplies and fan assemblies with power supplies and fan assemblies having the
opposite air flow direction. All fans and power supplies installed in an 8325 switch must have the same air flow
direction. For specific model information see the
“Overview” .
2. Install power supplies
Skip this step if a power supply is already installed in the switch.
If a power supply is not already installed in the switch, install at least one power supply before continuing in this
guide. The Aruba 8325 switch uses any of the following power supplies:
• Aruba 8325 650W 100-240VAC FB PSU (JL632A)
• Aruba 8325 650W 100-240VAC BF PSU (JL633A)
• Aruba 8325 850W 48VDC FB PSU (JL861A)
• Aruba 8325 850W 48VDC BF PSU (JL862A)
If a power supply must be removed, and then reinstalled, wait at least 5 seconds before reinstallation.
Otherwise, damage to the switch may occur.
The power supply needs this time to bleed off any retained power.
To avoid personal injury or product damage, review “Installation precautions” before beginning the
installation.
A red-colored power supply release lever indicates a Front-to-Back (FB) air flow. A blue-colored power
supply release lever indicates a Back-to-Front (BF) air flow.
