SAS/ SATA and SSD drive guidelines
When adding drives to the server, observe the following general guidelines:
Drives must be the same capacity to provide the greatest storage space efficiency when drives are
grouped together into the same drive array.
Drives in the same logical volume must be of the same type.
Hardware problem troubleshooting
Power problems
Power source problems
1.
Press the Power On/ Standby button to be sure it is on. If the server has a Power On/ Standby button
that returns to its original position after being pressed, be sure you press the switch firmly.
2.
Plug another device into the grounded power outlet to be sure the outlet works. Also, be sure the
power source meets applicable standards.
3.
Replace the power cord with a known functional power cord to be sure it is not faulty.
4.
Replace the power strip with a known functional power strip to be sure it is not faulty.
5.
Have a qualified electrician check the line voltage to be sure it meets the required specifications.
6.
If Enclosure Dynamic Power Capping or Enclosure Power Limit is enabled on supported servers, be
sure there is sufficient power allocation to support the server.
7.
Be sure no loose connections exist.
Power supply problems
1.
Be sure no loose connections exist.
2.
If the power supplies have LEDs, be sure they indicate that each power supply is working properly. If
the LEDs indicate a problem with a power supply(6.7Hz flashes green for 650W fixed PSU, yellow is
on for 800W or 500W RDN PSU), then check the power source. If the power source is working
properly, then replace the power supply.
If the 6.7Hz green LED is flashing for 650W fixed PSU, yellow LED is on for 800W or 500W RDN
PSU, it could mean any of the following:
o
AC power unavailable
o
Power supply failed
