Upgrading the 1200-Watt, AC-Input
Power Supplies in the Cisco 7513
This document contains instructions for upgrading your existing Cisco 7513, 1200-watt (W), alternating
current (AC)–input power supplies, with new AC-input power supplies. (See .) A single power supply is
standard equipment for the Cisco 7513. 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

The power supplies feature the following three safety interlock features: • An on/off switch with a locking mechanism on each power supply prevents the power supply from being removed from the chassis when the power supply switc

Product Overview • A spring clip on the AC receptacle supplies strain relief and prevents the power supply power cable from being pulled out accidentally. Environmental Monitoring and Reporting Functions The environmental monitoring and reporting functions, controlled by the chassis interface board, enable you to maintain normal system operation by identifying and resolving adverse conditions prior to loss of operation. The environmental monitoring functions constantly monitor the internal cha

Product Overview • Power supply shutdown—An out-of-tolerance voltage, current, or temperature condition was detected within the power supply and it was shut down (or a shutdown is imminent). All DC power remains disabled until the operator toggles the power switch and corrects the problem that caused the shutdown (if any). This condition typically occurs because of one of the following reasons: – Loss of AC input power (the power source failed). – Power supply detected an overvoltage, overcurr

Product Overview Environmental Reports The system displays warning messages on the console if chassis interface-monitored parameters exceed a desired threshold or if a blower failure occurs. You can also retrieve and display environmental status reports with the show environment, show environment all, show environment last and show environment table commands. Parameters are measured and reporting functions are updated every 60 seconds. A brief description of each of these commands follows. Cau

Product Overview The show environment table command displays the temperature and voltage thresholds for each of the three RSP2 temperature sensors, for each monitored status level: low critical, low warning, high warning, and high critical, which are the same as those listed in Tables 2 and 3. The slots in which the RSP2 can be installed are indicated in parentheses (6 and 7). Also listed are the shutdown thresholds for the processor boards and power supplies.

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, yo
