24 System Hardware Guide
The connectivity and functionality for the LED(s) for each NIC is as follows:
NVRAM PCI-X : The 512MB and 1024NB NVRAM card has multiple LEDs. The LEDs from the
bottom to the top are:
•
A Test LED switch that lights the three NVRAM LEDs to test their functionality
•
A power on/off indicator that glows green when powered on
•
A fault indicator for the two batteries on the NVRAM card. The LEDs will flash if the batteries
are discharged. If the batteries remain discharged after five hours, the LEDs remain on
constantly.
•
The LED labeled Remove is not used.
Single Port SAS PCIe HBA : Each SAS HBA port accepts a Infiniband style SAS connector
(SFP-8470) and has two LEDs.
•
The LED on the right flashes when the card has power and is ready for use.
•
The LED on the left flashes when data passes between an expansion shelf and the Data
Domain system
Dual Port SAS PCIe HBA : Each SAS HBA port accepts a miniSAS connector (SFF-8088) and
has two LEDs.
•
The LED on the right flashes when the card has power and is ready for use.
•
The LED on the left flashes when data passes between an expansion shelf and the Data
Domain system.
Dual port 2Gb Fibre Channel PCI-X HBA for Gateway Storage : Each 2Gbps Fibre Channel
port accepts an LC connector and has three LEDs.
•
All three LEDs flash at the same time when power is on and the port has no online connection.
•
The yellow LED on the left glows steadily when a 4 Gbps online connection is live and flashes
with I/O activity.
•
The other two LEDs are for 2 Gbps and 1 Gbps links. All LEDs flash alternately for a firmware
error.
Dual port 4Gb Fibre Channel PCIe HBA for Gateway Storage : Each 4Gbps Fibre Channel port
accepts an LC connector and has three LEDs.
•
All three LEDs flash at the same time when power is on and the port has no online connection.
•
The yellow LED on the left glows steadily when a 4 Gbps online connection is live and flashes
with I/O activity.
•
The other two LEDs are for 2 Gbps and 1 Gbps links. All LEDs flash alternately for a firmware
error.
