1 Hot-swap redundant power supply 2 (available in some models)
2 Hot-swap redundant power supply 1
The hot-swap redundant power supplies help you avoid significant interruption to the operation of the
system when a power supply fails. You can purchase a hot-swap redundant power supply option from
Lenovo and install the power supply to provide power redundancy without turning off the server.
On each hot-swap redundant power supply, there is a status LED near the power cord connector. When the
LED is lit in green, it indicates that the hot-swap redundant power supply is working correctly. When the LED
is lit in amber, it indicates that the hot-swap redundant power supply is likely to fail or has failed.
3 PCI Express card area for cards on the riser card assembly 2
There are three PCI Express card slots on the riser card assembly 2 for installing Ethernet cards or other
supported PCI Express cards.

Notes:
• The slot 1 and slot 2 are supported only in server models with two microprocessors. For server models
with one microprocessor, the slot 1 and slot 2 are covered. If you install the second microprocessor
in the server, you need to remove the covers that protect the slot 1 and slot 2 before installing any
supported cards into the slots.
• If a ThinkServer Host Bus Adapter is available, refer to its user guide for detailed information. The user
