Adding NICs to Your px12-400r Network Storage

You can add an accessory high performance (10GbE) network interface card to your px12-400r, which
provides two additional NICs. This provides more ports you can connect to different physical networks and
increases flexibility when connecting to a single network or multiple networks. The additional external
NICs can be bonded with each other or with internal NIC ports. You can also use the added NICs to
configure your px12-400r to have multiple IP addresses and create more VLANs.
Wake on LAN is not supported for add-on NICs. For more information on that setting, refer to
Energy Saving
To add an accessory network interface card, follow this procedure:
1. Shut down your px12-400r and remove its cover.
2. Locate a vacant expansion slot at the back of the px12-400r and remove the expansion slot cover.
Save the expansion slot cover screw.
3. Insert the Ethernet card into the expansion slot and push the connector on the card firmly into the
slot until it is completely seated. Make sure the card bracket is flush against the px12-400r
chassis.
4. Replace the slot cover screw.
5. Replace the cover on the px12-400r and power it on.
The px12-400r Network Storage automatically recognizes the new network interface and lists the added
NICs on the Network page.
Special Considerations when Bonding 10GbE NICs
The two 10Gb ports are the only connected (active) NICs:
All bonding modes are fully supported. As with any bonded NIC, you can select only one bonding
●
mode (Adaptive Load Balance, Link Aggregation, or Failover).
10Gb transfer speed will always be used for the bonded NIC (if supported by a 10Gb network
●
switch).
If the selected bonding mode is Adaptive Load Balance or Link Aggregation, the bonded NIC will
●
provide 2 x 10Gb bandwidth, so it will be able to transfer twice as many network packets
simultaneously. (Network transfer speed remains 10Gb.)
10Gb and 1Gb ports connected and bonded in failover mode:
When bonding multiple 10Gb and 1Gb ports, Failover is the only supported bonding mode. In Failover
mode, only one of the bonded NICs is active. All other connected NIC ports will be used as backup for the
primary NIC.
Network transfer speed for the px12-400r will be determined by the primary NIC in the bonded
●
configuration. This means the transfer speed will be 1Gb if a 1Gb port is the primary NIC, even if
the bonded configuration includes a 10Gb port.
The primary NIC is the first network interface selected when configuring the bonded NIC.
If the primary 10Gb NIC fails, one of the backup NICs will become the active (primary) interface.
●
If this is a 1Gb NIC, the network speed for the px12-400r will be reduced to 1Gb.
Some 10Gb and 1Gb ports bonded in Failover mode with other 1Gb ports also connected:
