700-Watt AC-Input Power Supply Installation and Replacement Instructions
Product Numbers: PWR/7-AC and PWR/7-AC=
This document contains instructions for installing or replacing a 700-watt (W), AC-input power supply in the Cisco 7000 and Cisco 7507 chassis.
One 700W power supply is standard equipment in the chassis. A second, identical power supply, when installed, provides redundant power. In systems with redundant power, the power supplies are load-sharing and fully hot-swappable; you can remove and replace one supply, while the remaining supply immediately ramps up to full power to maintain uninterrupted system operation.
The sections in this document include the following:
The 700W power supply is a modular power supply for the Cisco 7000 and Cisco 7507 multiprotocol, multimedia routers. One 700W power supply is standard equipment in the chassis. A second, identical power supply, if installed, provides redundant power. Power supplies reside in power supply bays in the rear of the router chassis, as shown in Table 1 on page 4. The lower power supply bay contains the first (standard) power supply, and the upper bay contains the second supply in systems with redundant power. Power supplies reside in power supply bays in the rear of the router chassis, as shown for the Cisco 7000 in Figure 1 and the Cisco 7507 in Figure 2.
Figure 1 AC-Input Power Supplies in the Cisco 7000
The lower power supply bay contains the first (or standard) power supply, and the upper bay contains the second (optional) supply in systems with redundant power.
Figure 2 AC-Input Power Supplies in the Cisco 7507
Dual power supplies are automatically load-sharing and redundant, which means that you can install or replace a second power supply on line. During normal operation, dual supplies provide system power simultaneously (load sharing). When you remove one supply, the remaining supply immediately ramps up to provide full power and maintain uninterrupted power to the system. Whenever possible, connect each power supply to a separate AC source. For example, connect one to a standard wall outlet and the other to an uninterruptible power supply (UPS). If there is a power failure, the power supply connected to the UPS maintains uninterrupted system power.
Table 1 lists the chassis power specifications for the AC-input power supply.

On the chassis front panel, the upper power and lower power LEDs go on when the power supply in the corresponding bay is installed and supplying power to the system. Both the upper and lower power LEDs should go on in systems with redundant power. In addition to the chassis front panel LEDs, each power supply contains AC power and DC fail LEDs and individual power switches, which are shown in Figure 3.
Figure 3 Power Supply and Status Indicators
In systems with a single power supply, and in systems with redundant power when both power supplies are shutting down, the DC fail LED goes on momentarily as the system ramps down, but goes out when the power supply has completely shut down. In systems with redundant power and one power supply still active, the DC fail LED on the failed power supply will remain lit (powered by the active supply).
A modular power cord connects each power supply to the site power source. A cable retention clip on the power supply AC receptacle prevents the cable from accidentally being pulled out. The power supplies feature the following three safety interlock features:
Figure 4 Power Supply Safety Interlocks
The power supplies are self-monitoring. Each supply monitors its own temperature and internal voltages. An internal fan in each power supply draws cooling air from the front of the chassis, through the power supply, and out the back of the chassis. An air dam keeps the power supply airflow separate from that of the rest of the chassis (which is cooled by the system blower).
For a complete description of the power supply, refer to the Cisco 7000 Hardware Installation and Maintenance or Cisco 7507 Hardware Installation and Maintenance publications.
Before you begin this installation, review the safety guidelines in this section to avoid injuring yourself or damaging the equipment. This section also provides power requirements to consider if you are adding a second power supply to your system for redundant power, and lists of the tools and parts you need to perform this installation.

The following guidelines will help to ensure your safety and protect the equipment. This list is not inclusive of all potentially hazardous situations, so be alert.
This section is only applicable if you do not have clear access to the power supply bays and must move a rack-mounted chassis. If you do have clear access to the power supply bays, proceed to the next section "Safety with Electricity." If space behind a rack-mounted chassis is limited, or if access to the power supply bays is partially blocked by a power strip or other equipment, you may have to slide the chassis partially out of the front of the rack in order to insert the power supplies. At least one person will have to support the front of the chassis while another person pushes it outward from the back and inserts the power supply. If you suspect that pushing the chassis out the front of the rack may topple the rack, make sure enough people are available to support the rack while you perform this procedure. The chassis weighs approximately 120 pounds with 1 power supply and 7 interface processors installed.Whenever you move or lift the chassis or any heavy object, follow these guidelines:
You can remove or install a redundant (second) power supply without turning off the other supply. Before removing a redundant power supply, ensure that the first supply is powered on to ensure uninterrupted operation. Follow these basic guidelines when working with any electrical equipment:
In addition, use the guidelines that follow when working with any equipment that is connected to telephone wiring or other network cabling:
The 700W, wide-input power supply uses a power factor corrector (PFC) that allows it to operate on input voltage and current within the ranges of 100--240 VAC and 50--60 Hz. When two power supplies are installed, the redundant power option assures that power to the chassis continues uninterrupted in the event that one power supply fails. It also provides uninterrupted power if an input power line fails only if the power supplies are connected to separate input lines. For maximum reliability, connect one power supply to a standard wall outlet and the other to a separate source, such as an uninterruptible power supply (UPS). If only one input line is available, and you must connect both power supplies to the same source, the redundant power supply will provide continuous power if the first power supply fails. It cannot, however, provide power backup if the input power fails. Table 1 on page 4 lists system power specifications including input voltage and operating frequency ranges.
This section lists the tools you will need to complete this installation. In most cases, you need only a screwdriver to install or replace a power supply. However, if the chassis is mounted in a rack and access to the power supply bays is partially blocked by a power strip or other equipment, or if you have less than three feet of working space at the rear of the rack, you may need to move the chassis, which requires additional tools.
You need the following tools to install or replace a power supply:
Before beginning the power supply installation, check the installation screws on all power supplies and check the area around the power supply bays to determine which tools you will need.
The new or replacement power supply and the power cord shipped with it are the only parts you need to complete this installation. If you remove a power supply and leave the bay empty, install a cover plate over the empty bay. The chassis is shipped with a cover plate installed over the upper bay. If the plate is not available, contact a service representative to order a replacement (Product Number MAS-7KPSCOVER).
The following section describes the procedures for removing an existing power supply and installing a new one. It also contains procedures for installing power supplies in rack-mounted chassis when the power supply bays are partially blocked.
If cables from other equipment are in front of the bay, move them aside and temporarily secure them with cable ties. If you must remove a rack-mounted chassis from the rack, proceed to the following section, "Removing a Rack-Mounted Chassis." Otherwise, if you now have clear access to the power supply bays, proceed to the section "Removing a Power Supply" on page 13 to replace an existing supply, or to the section "Inserting a Power Supply" on page 14 to install a new power supply for redundant power.
In systems with redundant power, you can install, remove, or replace one of the power supplies without affecting system operation. When power is removed from one supply, the redundant power feature causes the second supply to ramp up to full power and maintain uninterrupted system operation.
This section describes how to proceed if your system is installed in an equipment rack and you do not have clear access to the power supply bays. If the chassis is not in a rack, or if you already have clear access to the power supply bays, you do not need to perform these steps. Proceed to the sections that follow. If you determine that moving the chassis is unavoidable, you will need to disconnect all power and interface cables. Be sure to label the cables to avoid crossing them when you reconnect them to the chassis. The configuration worksheet provided at the end of this document can help you reconnect the cables to the correct ports if you complete it as you disconnect cables from the interface processors. (For the Cisco 7000, refer to Figure 6, and for the Cisco 7507, refer to Figure 7.)
To slide the chassis out of the front of the rack to gain access to the power supply bays, do the following:
If you are replacing the power supply in a single-supply system, remove the existing supply from the lower bay first, if possible, and install the new power supply in the lower bay to maintain a low center of gravity in the chassis (you will have to interrupt system operation to do so). Always install a filler plate over an empty power supply bay to prevent electrical shock and to protect the backplane connectors from contamination.
Follow these steps to remove a power supply:
Figure 5 Handling a Power Supply
If you are installing a replacement power supply, proceed to the next section. Otherwise, reconnect all power and interface cables on the rear of the chassis and restart the system.
Always install the first power supply in the lower power supply bay and the second, if any, in the upper bay. In systems with dual power supplies and when separate power sources are available, connect each power supply to separate input lines, so in case of an input line failure, the second source will most likely still be available.
To complete the installation you turn the power supply on and observe the LEDs on the power supply to verify that the new supply is operating properly.
If the power supply fails to operate properly after several attempts to initialize it, refer to the note on page 25 of this document and contact a service representative for assistance.
This completes the power supply installation. Refer to the Cisco 7000 Hardware Installation and Maintenance or Cisco 7507 Hardware Installation and Maintenance publications for installation-related troubleshooting procedures, and to the Router Products Configuration Guide publication for descriptions and examples of software features and commands.
