Power supply
Your server comes with one or two power supplies. When two power supplies are both installed, they
provide redundant and hot-swap features. Depending on the server model, the power supplies for your
server can be any of the following types:
• 450-watt, 90–264 V ac, universal input and compliant with 80 PLUS Gold
• 550-watt, 90–264 V ac, universal input and compliant with 80 PLUS Platinum
• 750-watt, 90–264 V ac, universal input and compliant with 80 PLUS Platinum
• 750-watt, 180–264 V ac, universal input and compliant with 80 PLUS Titanium
Note: If you are using uninterruptible power supplies (UPS), ensure that you use only pure-sine UPSes
with your ThinkServer server.
System fans
Your server supports up to six system fans. This design helps you avoid significant cooling problems
when a system fan fails.
Internal drives
Internal drives are devices that your server uses to read and store data. The internal drives supported
by your server vary by model.
• Internal storage drive
Your server supports one of the following storage drive configurations:
