700-Watt DC-Input Power Supply
Installation and Replacement Instructions
Product Number: PWR/7-DC and PWR/7-DC=
This document contains instructions for installing or replacing a direct current (DC)–input power
supply in the Cisco 7000 and Cisco 7507 chassis.
Note
therefore, throughout this document, both chassis are referred to as the chassis, with differences
clearly noted.
The DC-input power supply is optional equipment for the chassis. A second, identical DC-input
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. Sections in this document include the following:

system that is already operating. If you are installing a new system, and you ordered a copy, refer to
the Cisco 7000 Hardware Installation and Maintenance or Cisco 7507 Hardware Installation and
Maintenance publications. Because the chassis are shipped without the power supplies installed,
refer to these publications for initial power supply installation and startup procedures. Both of these
publications are also available on UniverCD.

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.
- Page 7 If you remove AC-input power supplies from a Cisco 7000 and replace them with Caution DC-input power supplies, you might need to replace the LED board in the Cisco 7000, if the chassis was shipped before November 1, 1994. In this earlier chassis, the LED circuitry will not recognize and indicate the presence of the new DC-input power supplies.
- Page 8 Installation Safety, ESD Precautions, and Tools Required • Do not perform any action that creates a potential hazard to people or makes the equipment unsafe. • Carefully examine your work area for possible hazards such as moist floors, ungrounded power extension cables, and missing safety grounds.
- Page 9 Installation Safety, ESD Precautions, and Tools Required Safety with Electricity 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.
- Page 10 Installation • Handle printed circuit boards, such as the arbiter, by the edges only; avoid touching the board components, traces, or connector pins. • Place removed printed circuit boards or components that contain boards on an antistatic surface or in a static shielding bag. Place a removed board component-side-up; place a removed processor module or fan tray board-side-up.
- Page 11 (For the Cisco 7000, refer to Figure 9, and for the Cisco 7507, refer to Figure 10.) This procedure might shift the chassis’ center of gravity toward the front of the rack and Caution may cause the rack or the chassis to tip.
- Page 12 Reconnect all interface cables to the ports on the rear of the chassis. If you completed the Step 10 configuration worksheet before you disconnected the cables, use it as a guideline to reconnect the cables. (For the Cisco 7000, refer to Figure 9, and for the Cisco 7507, refer to Figure 10.) Step 11 Proceed to the section “Checking the Installation”...
- Page 13 Installation Removing a Power Supply 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.
- Page 14 Installation Use a screwdriver to remove the three power leads from the terminal block. (See Figure 6.) Step 5 Use a screwdriver to reinstall the terminal block cover. (The terminal block cover should Step 6 stay with the power supply.) Do not overtighten the captive installation screws on the terminal block cover.
- Page 15 Installation Grasp the power supply handle and pull the supply out of the bay. Place one hand Step 8 underneath to support the bottom of the supply as you pull it out of the bay. (See Figure 7.) If the power supply resists when you attempt to pull it out of the bay, the switch is probably not fully in the OFF (O) position, or the captive installation screw at the top of the supply is not fully loosened.
- Page 16 If you remove AC-input power supplies from a Cisco 7000 and replace them with Caution DC-input power supplies, you might need to replace the LED board in the Cisco 7000, if the chassis was shipped before November 1, 1994. In this earlier chassis, the LED circuitry will not recognize and indicate the presence of the new DC-input power supplies.
- Page 17 To prevent problems with the Cisco 7000, do not mix DC-input and AC-input power supplies in the same chassis. Your Cisco 7000 must have either DC-input or AC-input power supplies.
- Page 18 Installation The illustration shows the DC power supply terminal block. Wire the DC power supply Warning using the appropriate lugs at the wiring end, as illustrated. The proper wiring sequence is ground to ground, positive to positive (line to L), and negative to negative (neutral to N). Note that the ground wire should always be connected first and disconnected last.
- Page 19 Checking the Installation Do not turn on any power supplies until you are ready to power up the system. The interlock Note switch that locks the power supply in the slot also turns on the system power. If you are installing or replacing a second power supply, repeat step 1 through step 11 for Step 11 the second power supply.
- Page 20 If you are currently using software other than Maintenance Release 9.17(10) or later in your Note Cisco 7000, then the show environment all command will indicate the AC-input power supply as “850W.” A DC-input power supply will still be indicated as “700W.”...
