［?］An error, retry, time-out, or a drive error not included in the guarantee occurs when an old Mini-SAS
cable is used.
The product life cycle of Mini-SAS connector is 250 times of connection/disconnection (outer, inner and

・Connect a USB device which needs less than 500mA of electricity.

［?］On the flow control of LAN Controller
In case Flow Control is set to "Auto Negotiation", "Rx & Tx Enabled", "Tx Enabled" or "transmission
enabled", or "transmission/reception enabled", when the packet processing of OS stops in the state of
heavy reception load due to system hang etc., PauseFrame might be transmitted continuously. In such
cases, due to massive pile-up of packets at the switch side, the buffer within the switch becomes
scarce and all communication devices connected to the switch may be affected. In order to avoid such
cases, set Flow Control to "Disabled" or "Invalid".
［?］Support of the FCoE function in N8104-173/177
For this product, NEC does not support the FCoE (FibreChannel over Ethernet) function.
The FCoE function is enabled regardless of the version of the firmware applied to the LOM card in
N8104-173, and for Family Firmware Version 8.35.43 or later in N8104-177.
Although it is recognized as a FCoE device on the OS, it does not affect operations as long as the use
of the function is not specified on the OS or driver.
The following devices may be ignored when detected.
-HPE 533FLR-T FCoE Device
-HPE 622FLR-SFP28 FCoE Device
