Maintaining the JSA5800 Power Supply

The JSA5800 appliances ship with redundant AC power supply modules. If one power supply fails, the
second power supply takes over for the entire power load.
NOTE: The JSA5800 also supports optional DC power supply modules if you need DC 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
JSA5800 appliance are securely in place and that there no moisture is accumulating near the
appliance.
To monitor the power supply modules, execute the following commands:
• To enable IPMI and boot, use # chkconfig ipmi on
• To start IPMI service, use service ipmi start
• To load IPMI driver, use modprobe ipmi_devintf
For example, the following load driver is displayed:
[root@hw-jsa5800 ~]# lsmod |grep ipmi
ipmi_devintf 7729 Ø
• For the IPMI hardware status, use # ipmitool sdr
