Product Overview

The AC redundant power supply has two integrated power modules, with redundant fans and alarm interfaces, to provide higher reliability and load balancing. These units contribute to higher availability times, and high reliability for mission critical applications.

You can use the redundant power supply to replace either a single-cord, non redundant power supply, or another redundant power supply.


Note For maximum reliability and availability, you should supply power to each of the Cisco AS5300 redundant power supplies from an independent AC power outlet. This insures that if one outlet fails, source powered by the other outlet will fully maintain the output of the redundant power supply.
If you can not accommodate this requirement, you may choose to use a single outlet for the power feed, but the resulting single point of failure will impact overall system redundant operations in the form of reduced availability.

The AC redundant power supply Y-cable is a foot-long 120-VAC power cable consisting of two standard IEC 320 receptacles that connect to the Cisco AS5300 AC Ingress and one standard IEC 320 plug that connects to either the Cisco AccessPath Cabinet AC power egress strip, or to the appropriate power extension cord for your site and country. Figure 1 shows the AC redundant power supply Y-cable.

The AC power cable retention clip is constructed only for connections from the Y-cable IEC 320 plug to a country-specific AC power extension cord. The cable ties required for the procedure explained in the "Constructing the AC Power Cable Retention Clip" section ship with the Y-Cable.



Warning   This unit has two power cables. To reduce the risk of electric shock, disconnect the two power supply cords before servicing the unit.

Warning   

Ultimate disposal of this product should be handled according to all national laws and regulations.

Your access server ships with a hardware quick start guide to help you quickly install the server and connect the necessary cabling. This quick start guide details the initial configuration of the server. Basic hardware installation instructions are described in the Cisco AS5300 Universal Access Server Chassis Installation Guide that accompanied your access server.

Maintain Safety with Electricity

Warning Before working on equipment that is connected to power lines, remove jewelry (including rings, necklaces, and watches). Metal objects will heat up when connected to power and ground and can cause serious burns or can weld the metal object to the terminals.

Follow these guidelines when you work on equipment powered by electricity.

  • Locate the emergency power-OFF switch for the room in which you are working. Then, if an electrical accident occurs, you can act quickly to turn OFF the power.

  • Before working on the system, unplug the power cord.

  • Disconnect all power before doing the following:

    • Installing or removing a chassis

    • Working near power supplies

Warning Read the installation instructions before you connect the system to its power source.
  • Look carefully for possible hazards in your work area, such as moist floors, ungrounded power extension cables, frayed power cords, and missing safety grounds.

  • If an electrical accident occurs, proceed as follows:

    • Use caution; do not become a victim yourself.

    • Turn OFF power to the system.

    • If possible, send another person to get medical aid. Otherwise, assess the condition of the victim and then call for help.

    • Determine if the person needs rescue breathing or external cardiac compressions; then take appropriate action.

Power Supply Considerations

Check the power at your site to ensure that you are receiving "clean" power (free of spikes and noise). Install a power conditioner if necessary.

Warning The device is designed to work with TN power systems.

The access server AC power supply Auto ranges input from 100VAC to 240VAC operation.

Warning This product relies on the building's installation for short-circuit (overcurrent) protection. Ensure that a fuse or circuit breaker no larger than 120 VAC, 15A U.S. (240 VAC, 10A international) is used on the phase conductors (all current-carrying conductors).

Hardware Supported

Cisco recommends that you feed power from independent AC power outlets to each power module in the Cisco AS5300 redundant power supply. Should it be necessary to feed both power modules from a single AC power outlet, you can use the Y-cable to do so.

In this single-outlet configuration:

  • If you are rack-mounting a Cisco AS5300 in either an Cisco AccessPath-TS3 or Cisco AccessPath-VS3 cabinet, then only the Y-Cable is required.

  • If you are not rack-mounting a Cisco AS5300 in an AccessPath cabinet, then you must supply one country-specific AC power extension cord for each Cisco AS5300.

You can order country-specific AC power extension cords from Cisco. See the "Hardware Required" section for more information.

Hardware Required

Unless you are installing your Cisco AS5300 into a Cisco AccessPath Cabinet, you must provide 1 or 2 AC power extension cable for each Redundant Power version of the Cisco AS5300.

You can order these country-specific AC power extension cord from Cisco with the following order numbers:

Order Number Country-type

CAB-AC-Y-AS=

U.S.

CAB-ACA-Y-AS=

Australia

CAB-ACE-Y-AS=

Europe

CAB-ACI-Y-AS=

Italy

CAB-ACR-Y-AS=

Argentina

CAB-ACU-Y-AS=

U.K.



The male connector of this country-specific AC power extension cord must be compatible with your site's power supply outlets, and the female connector must be a standard IEC 320 receptacle.

Figure 3 illustrates this extension cord, and shows the order numbers available for the various countries.

Connecting the AC Y-Cable to the Cisco AS5300

This step is only required if you will feed power from a single AC power outlet to both power modules in the redundant power supply.

If this is not the case, you can feed power from independent outlets into each power supply as you would in the single-power-supply configuration. Your Cisco AS5300 is then configured to follow the standard startup procedures described either:

  • beginning with step 2 on page 3-8 of the Cisco AccessPath Model 531 Hardware Upgrade and Configuration Guide if the Cisco AS5300 is installed in a Cisco AccessPath Cabinet.

  • in the Cisco AS5300 Universal Access Server Chassis Installation Guide if the Cisco AS5300 is not installed in a Cisco AccessPath Cabinet.

Complete Step 1 through Step 2 to construct the AC power cable retention clip:


Step 1   Connect the Y-cable to the cabling side of the Cisco AS5300 as shown in Figure 1.

Step 2   Close the bale clips to secure the Y-cable's IEC 320 receptacles.

You can now connect theY-cable's IEC 320 plug to either:


Figure 1: Connecting the AC Y-Cable to the Cisco AS5300 AC Ingress


Connecting the AC Y-Cable to the Cisco AccessPath Cabinet


Note This step is only required if you are installing the Cisco AS5300 in a Cisco AccessPath Cabinet.

Step 1   Connect the Y-Cable's IEC 320 plug to the AC power egress strip as shown in Figure 2.


Figure 2: Connecting the AC Y-Cable to the Cisco AccessPath Cabinet AC power egress strip


The Cisco AS5300 is now configured to follow the standard startup procedures described beginning with step 2 on page 3-8 of Cisco AccessPath Model 531 Hardware Upgrade and Configuration Guide.

Constructing the AC Power Cable Retention Clip


Note This step is required unless you are installing the Cisco AS5300 in a Cisco AccessPath Cabinet, and you are feeding power to both power modules in the redundant power supply from a single AC power outlet.
Caution Confirm that the country-specific AC power extension cord is not connected to any power supply, and remains so until you reach the final step of this procedure.

Complete Step 1 through Step 7 to construct the AC power cable retention clip:


Step 1   Firmly connect the Y-cable's standard IEC 320 plug to your extension cord's standard IEC 320 receptacle. Figure 3 shows the order numbers for the five power cables orderable from Cisco.


Figure 3: AC power cable retention clip Connecting to Local Power Extension Cable


Step 2   Wrap and loosely secure the shorter cable ties around the strain-relievers of the connections that you connected in Step 1. (See Figure 4)

Step 3   On opposite sides of the power cable connection, wrap and loosely secure each longer cable tie through the rings that you created in Step 2, thereby linking those 2 rings. (See Figure 4)


Figure 4: AC Power Cable Retention Clip with Cable Ties Loose


Step 4   Tighten the rings around the strain-relievers of the connectors until the longer cable ties barely slide through the rings.

Step 5   Tighten the longer cable ties until the power cable is firmly secured. (See Figure 5)


Figure 5: AC Power Cable Retention Clip with Cable Ties Tight


Step 6   Confirm that the Cisco AS5300 power switch is turned off.

Step 7   Connect the country-specific AC power extension cord to the AC power outlet.

The Cisco AS5300 is now configured to follow the standard rack-mounting or installation procedures as described in Cisco AS5300 Universal Access Server Chassis Installation Guide.
