 1. Before you Begin

  • This article uses details from the PowerStore Hardware Information Guide.
  • Each Node contains one embedded module that can hold one 4-port card for front-end connectivity and internal communication between nodes and appliances.
  • This article will include a diagram from Node A (bottom node). Node B will have the same LED indicator structure, however it is inverted as the Node is installed upside down in the Enclosure.  
     

 2. Base Enclosure Front View


The front of the base enclosure contains the following elements:

 4. Embedded Module View

  • Each node contains one embedded module that can hold one 4-port card for front-end connectivity and internal communication between nodes and appliances.
  • The first two ports of the 4-port card on the embedded module connect to a 10GbE/25GbE Ethernet switch.
  • Note: Both nodes must have the same type of embedded modules in the same slots.
  • The embedded module contains the following components:
  • One 4-port card
  • One non-maskable interrupt (NMI) button
  • Two mini-SAS HD back-end ports
  • Two RJ-45 LAN connectors
  • System management Port
  • Service Port
  • One USB port.
  • One mini serial port
  • One DB9 serial port
