ZS3-2 Front and Rear Panel Components

Language:

ZS3-2 Front Panel Components - The ZS3-2 controller drive slots and front panel components are shown in the following figure.

Figure 35 ZS3-2 Controller Front Panel

Note - The three Cluster I/O ports (0, 1, and GigE) are reserved for cluster interconnection only.

Cluster Interface Compatibility - The ZS3-2 controller contains embedded support for Version 2 clustering ports. It does not have a cluster interface card nor can one be installed in a PCIe slot.

Ethernet Ports

The ZS3-2 has four RJ-45 10-Gigabit Ethernet (10GbE) network connectors, labeled NET 3, NET 2, NET 1, and NET 0 (left to right) on the rear panel. The ports operate at 100 Mbits/sec, 1000 Mbits/sec, or 10-Gbits/sec. Use these ports to connect the appliance to the network.

Table 27 ZS3-2 Ethernet Port LEDs Description

Connection Type	EEE Terminology	Speed LED Color	Transfer Rate
Fast Ethernet	100BASE-TX	Off	100 Mbits/sec
Gigabit Ethernet	1000BASE-T	Amber	1000 Mbits/sec
10 Gigabit Ethernet	10GBASE-T	Green	10000 Mbits/sec

The LEDs located above each NET port are Link/Activity (left) and Speed (right) indicators for each port.

Network Management Port

The network management connector (NET MGT) is an RJ-45 10/100 BASE-T Ethernet port and provides an alternate terminal interface to the SP console.

Serial Management Port

The serial management connector (SER MGT) is an RJ-45 port and provides a terminal connection to the service processor (SP) console.

Cluster I/O Ports

Two cluster serial ports (0 and 1) and one Ethernet port provide communication between two controllers to form a cluster configuration. For information about how to connect cables to form a cluster, see ZS3-2 Controller Cluster I/O Ports in Oracle ZFS Storage Appliance Cabling Guide.

Caution - When disconnecting an RJ-45 cable from a cluster serial port (0 and 1), use extreme care not to damage the internal RJ-45 receptacle. To properly remove an RJ-45 cable from a cluster serial port, do the following:

4x4 SAS HBA

The 4x4 SAS HBA, installed in PCIe slot 2 of the ZS3-2, provides connectivity to external disk shelves. The HBA logical ports are numbered 0-3, as shown in the following figures.
