PCIe Slots - The Oracle ZFS Storage ZS4-4 base configuration contains the following PCIe cards:
- Slot 2 - One 8-port SAS-2 internal HBA
- Slot 4 - One cluster interface card
- Slots 6 and 7 - Two 4-port (4x4) SAS external HBAs

For information about PCIe slot order, see Oracle ZFS Storage ZS4-4 PCIe I/O Cards in Oracle ZFS Storage Appliance Customer Service Manual, Release OS8.8.x.

Ethernet Ports - Oracle ZFS Storage ZS4-4 has four RJ-45 10-Gigabit Ethernet (10GbE) network connectors on the rear panel, labeled NET 0, NET 1, NET 2, and NET 3 (bottom left to top right), as shown in the following figure. Use these ports to connect the appliance to the network.

The LEDs located above the NET ports, labeled 2, 0, 3, 1 (left to right) are Link/Activity indicators.
