Maintaining the JSA3800 Power Supply
The JSA3800 appliance ships with two AC power supply modules. If one power supply
fails, the second power supply takes over the entire power load.
NOTE: The JSA3800 appliance also supports DC power supply modules.
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 JSA3800 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-jsa3800 ~]# lsmod |grep ipmi
