The NIC LEDs at the right and left of each NIC provide the following information.
Hot-Swap Backplane
The Intel
®
Server System SR2520SAX/SR2520SAXS and SR2520SAXR/
SR2520SAXSR supports a backplane. The backplane provides the platform support for
peripheral drives and hot-swap SAS or SATA hard drives. To eliminate several cables, the
backplanes are also used as a pathway for signals from the server board to various
platform interconnects, including those for the control panel and peripheral drives. The
backplane acts as a 'pass-through' for the SAS/SATA data from the drives to the SATA
controller on the server board or a SAS/SATA controller add-in card. It provides the
physical requirements for the hot-swap capabilities.

®
Server System SR2520SAX/SR2520SAXR ships with a passive backplane with 6
SATA cables installed. The Intel
®
Server System SR2520SAXS/SR2520SAXSR ships with
an active backplane with 2 SAS cables installed.
