The Service LAN Port location is shown here with number 5.
If in doubt (because one of the nodes is inverted), pay attention to the arrows in the middle of the two ports. Follow the yellow port with the tool (service) symbol.
ATTENTION: Do not remove the management cables as this makes the system inaccessible to the user over the network (affects management only).
The service laptop being used to connect to the Service LAN Ports should be configured with:
IP: 128.221.1.249 Mask: 255.255.255.0 Gateway: <none>
The laptop can be physically connected to one of the PowerStore nodes at a time, or to both nodes' Service LAN ports using a small switch or hub.
However, multiple appliances should never be connected to the same hub or switch as the nodes use the same internal IPs. Never connect multiple appliances to the same hub or switch for Service LAN port access.
Once the laptop IP is configured as shown above and the physical connection is established, you can ping the relevant IPs:
Node A: 128.221.1.250 Node B: 128.221.1.251
You should only be able to ping the IPs where you are physically connected to. If you can ping, move to the next section, otherwise check your settings and physical connection.
Example
Access over the normal mgmt IP and the Service LAN IP should produce the same results.
