6. Plug the AC power cord (5) into the main AC power outlet (7), preferably on a dierent circuit for
better redundancy.
The AC OK and DC OK LEDs on the front of the power supply turn green to indicate that the connection
was successful and the power supply is operating properly.
If the LEDs do not light properly, follow these steps to troubleshoot:
• Check the AC power cord connection at the AC power source and make sure the power source is
within specification.
• Check the AC power connection to the power supply.
• Swap the AC power cord with one that is known to work properly.
Installing a VX-RPS-1000 Redundant Power Supply
The VX-RPS-1000 redundant supply (Part no. 18202) is designed as a backup power source for the
V400 Virtual Port Extender.
You can install the VX-RPS-1000 in a 19-inch rack in either of two ways:
• Installing a Single VX-RPS-1000 Power Supply in a Rack on page 290
• Installing up to Three VX-RPS-1000 Power Supplies on a Shelf on page 291
Caution
Observe all ESD precautions when handling sensitive electronic equipment.
Locate each VX-RPS-1000 unit within 6 ft (1.8 m) of its power source.
Only qualified personnel should install redundant power supply (RPS) units.
Installing a Single VX-RPS-1000 Power Supply in a Rack
To install the VX-RPS-1000 power supply in a 19-inch rack, you need four customer-supplied screws to
attach the power supply to a standard 19-inch rack.
Caution
Observe all ESD precautions when handling sensitive electronic equipment.
Caution
Before rack-mounting the device, ensure that the rack can support it without compromising
stability. Otherwise, personal injury and/or equipment damage can result.
To install a single VX-RPS-1000 power supply in a rack, follow these steps.
1. Use screws (provided) to attach a long bracket to one side of the power supply.
Use the holes closest to the rear of the power supply.
