Replacing Older AC-Input Power Supplies

•If access to the power supply bays is partially blocked by a power strip or other permanent rack fixture, you will need a 1/4-inch flat-blade screwdriver to temporarily detach the ears from the equipment rack mounting strips.

•ESD-preventive wrist strap.

•At least one new AC-input power supply, Part Number 34-0667-01. (Replaces power supply Part Number 34-0049-01.)

Note If you have a Cisco 7513 with one or two of the older AC-input power supplies, you must replace both with the new AC-input power supplies. All Cisco 7513 chassis must have the new power supplies installed in them.

•AC-input power cords from your currently installed power supplies.

Note The new AC-input power supplies, which are included with this upgrade, do not ship with new AC-input power cords.

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 power supply and the power cable, that you supply, are the only parts you need to complete this installation.

If you remove a power supply and leave the bay empty, install a power supply blank in the empty power supply bay. (See .) Chassis shipped with a single power supply include a power supply blank installed in the empty power supply bay.

Circuit Protection Requirements

Based on the NFPA 70 National Electrical Code, you should use a 35A overcurrent protector to meet the requirement for the overcurrent protector size of 125 percent of the load current, which is approximately 27A. An overcurrent protector rated for 30A can be used only if it has been listed by the safety agency for operation at 100 percent of its rating.

Replacing Older AC-Input Power Supplies

The following procedures describe removing the older power supplies from your Cisco 7513 (Part Number 34-0049-01 or later), and installing new power supplies (Part Number 34-0667-01 or later).

All power supplies rest on the floor of the chassis under the card cage.

Note If cables from other equipment are in front of the bay, move them aside and temporarily secure them with cable ties.

Warning Although it is not necessary to turn OFF both power supplies to remove one of two power supplies, you must turn OFF the power to the power supply you plan to remove. When the power is on with one of two power supplies removed, high current is exposed on the power connector inside the chassis. If you have only one power supply, you must turn OFF the power to this power supply.
