(Optional) Installing an RPS150 Power Supply

(Optional) Installing an RPS150 Power Supply

Context

NOTE:

The AR2204 and AR2220E can connect to an RPS150 power supply.

An RPS150 is a redundant power supply system that provides power redundancy for the connected routers to ensure uninterrupted services. When the internal power module of a router fails, the RPS150 can detect the power failure and supply power to the router immediately. The router can continue running without a restart, which improves system reliability.

An RPS150 can provide power redundancy for a router to ensure uninterrupted services.

  • If the RPS150 and router are connected to the same external power supply system, the RPS150 can prevent service interruption caused by failures of the router's internal power module.
  • If the RPS150 and router are connected to different external power supply systems, the RPS150 can prevent service interruption caused by failure of the router's internal power module and external power supply system. Therefore, this deployment is more reliable.

To avoid electric shock, do not connect power cables while the power is on.

  • Each router has its own power cables delivered as accessories. The power cables can only be used on the router in the same package and cannot be used on any other device.
  • RPS cables are not hot swappable.

Tools and Accessories

  • ESD wrist strap
  • Phillips screwdriver
  • Flat-head screwdriver
  • Floating nuts
  • Mounting brackets
  • Screws
  • RPS cable
  • RPS AC power cable

Procedure

  1. Wear an ESD wrist strap. Ensure that the ESD wrist strap is grounded and in a close contact with your wrist.
  2. Use a Phillips screwdriver to fix the front mounting brackets at both sides of the RPS150 with M4 screws.



  3. Install floating nuts.

    Install two floating nuts on each front mounting rail. Leave a mounting hole between the two floating nuts on the same mounting rail.

    NOTE:
    • The length of three adjacent mounting holes may not be 1 U. Observe the scale ticks on the mounting rails when installing floating nuts.
    • You can use a flat-head screwdriver to install floating nuts.


  4. Support the bottom of the RPS150 with one hand and tighten the screws on the mounting brackets with the other hand. Tighten the lower screws first, and then the upper screws.



  5. Connect the RPS cable.
    1. Put the TOP side of the RPS cable plugs upwards. Connect one end of the RPS cable to the RPS input interface on the router, and connect the other end to the RPS output interface on the RPS150.
    2. Tighten the captive screws at two sides of the RPS cable plugs clockwise.



  6. Connect the RPS AC power cable.

    Connect one end of the RPS AC power cable to the power jack of the RPS150 and the other end to an AC power outlet. Connect the RPS AC power cable to the same power supply system as the router or a different power supply system, depending on the reliability requirement.

  7. Connect the AC terminal locking latch.
    1. Insert the AC terminal locking latch into the jack on the rear panel of the router.
    2. Adjust the AC terminal locking latch to a proper position.
    3. Lock the AC power cable with the AC terminal locking latch.
