Power Supply

The JSA7500 appliance ships with redundant DC power supplies and also supports AC power supply option if you need AC power.

To maintain the power supplies, follow these guidelines:

  • Ensure that the power and grounding cables are arranged so that they do not obstruct access to other components.

  • Routinely check the power LED on the power supply module. If the LED status is green, the power supply is functioning normally.

  • Periodically inspect the site to ensure that the grounding and power cables connected to the JSA appliance are securely in place and that there is no moisture accumulating near the appliance.

To monitor the power supply modules, execute the following files which are available at the Juniper Customer Support website, www.juniper.net/support/downloads:

  • Install rpm –ivh i2c-tools-3.1.0-1.el6.x86_64.rpm

  • ./pwr_status_jnpr.sh
