5. Connect the other end of the power cord to an AC power outlet.
Warning
Always be sure that the source outlet is properly grounded before plugging the AC power
cord into the AC power supply.
Caution
Make sure that the AC power supply circuit is not overloaded. Use proper overcurrent
protection, such as a circuit breaker, to prevent overcurrent conditions.
Installing an RPS-150XT Redundant Power Supply
You can install the RPS-150XT power supply on a flat surface or in a 19-inch rack in the three-slot
modular shelf (STK-RPS-1005CH3), which is available for purchase separately.
Caution
Observe all ESD precautions when handling sensitive electronic equipment.
Only qualified personnel should install redundant power supply (RPS) units.
Unpacking the RPS-150XT
To prevent electrostatic damage, attach an electrostatic discharge (ESD) wrist strap to your wrist before
handling the RPS-150XT.
Unpack the power supply as follows:
1. Remove the packing material protecting the power supply.
2. Perform a visual inspection of the power supply for any signs of physical damage. Contact Extreme
Networks if there are any signs of damage.
Installation Requirements
The installation site must be within reach of the network cabling and meet the following requirements:
• Appropriate grounded power receptacles must be located within six feet of the site.
• A temperature of between 0°C (32°F) to 60°C (140°F) with
fluctuations of less than 10°C (18°F) per
hour must be maintained.
• A readily accessible disconnect device shall be incorporated into the building wiring.
A Phillips screwdriver and four rack screws (not supplied) are needed to install the RPS-150XT in a rack
using the three-slot modular shelf.
