Memory
Your server has 20 memory slots. For more information, see “Memory module installation rules” on page 86.
Power supply
One or two 800-watt hot-swap redundant power supplies (Universal input and compliant with 80 PLUS Gold)
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 six hot-swap system fans with redundancy, which means that five system fans can
provide adequate cooling while the extra one serves as a redundant system fan. This design helps you to
avoid significant cooling problems when a system fan fails and you can replace a hot-swap system fan
without turning off the server.
