 1. Before Starting

• This article uses details from the PowerStore Hardware Information Guide.
• Each Node contains one embedded module that can hold one 4-port card for frontend connectivity and internal communication between nodes and appliances.
• This article includes a diagram from Node A (bottom node). Node B has 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:

 3. Base Enclosure Back View

• The rear of the base enclosure contains two nodes: NodeA and NodeB.
• Each Node contains the following hardware components:
• One embedded module
• Two optional I/O modules
• One power supply module

 

Location	Description

 4. Embedded Module View

• Each node contains one embedded module that can hold one 4-port card for frontend 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 backend ports
• Two RJ45 LAN connectors
• System management Port
• Service Port
• One USB port
• One mini serial port
• One DB9 serial port

Embedded module and 4-port card LED status:

		Off	No fault has occurred, normal operation.
Ethernet port link	2	Green	Link established.
		Off	No link established
Ethernet port activity	3	Amber blinking	Port activity.
		Off	No port activity
SAS port link	4	Blue	SAS port link is up.
		Off	No link established
Port link	5	Green	Link up with high speed.
		Amber	Link up with degraded speed.

6. Base Enclosure Power Supply

• Each node of the base enclosure contains a power supply.
• If a power supply fails on a node, the other power supply maintains the power for the entire appliance.

Base enclosure power supply LEDs:

 

LED	Location	State	Description
Fault	1	Solid amber	Power supply or backup fault. check cable connection.
		Off	No fault
DC power (output) - Not Supported	2	Green	N/A
		Off	N/A
AC power (input)	3	Green	AC power is on.
		Off	AC power is off. Verify the power source.
