4 Hardware Check
Once the host computer has booted up, check the expansion unit and verify that all LEDs are correctly illuminated. A fully operational
expansion chassis will show the following LEDs.

LinkUP LED: Target card and Host card, CBL and EDG LEDs both should be illuminated as solid green.

Target Slot LED "D1" should be ON as solid green.

Front LEDs: PWR and FAN should be illuminated solid green.

Power Supply LED Indicator: should be ON as solid green.
The rear part of the expansion unit will show two solid green LEDs on both power supplies and two solid green LEDs on each target card.
4.1 LinkUP LED (CBL & EDG)
The LED indicators (CBL & EDG) on both Target and Host cards will come up as solid green. This is an indication that there is a LINK between
host and chassis. The Linkup LEDs represent only an initial connection/handshake between the chassis and host computer. A successful linkup
does not represent transfer or exchange of data.

The CBL LED shows the link status between the host card in the host computer and the target card in the expansion chassis.

The EDG / EDGE shows:

HOST card – connection between host card and host system

TARGET card – connection between the switch on the target card and the switch in the expansion chassis.
4.2 Target Slot & PWRGO LEDs
The “Target Slot LED” is located on the bottom part of PCIe slot. This LED (D1) should be ON as solid green. This represents that Link is up at
Gen 3 speed. The PWRGO LED, signifies that the card is powered UP correctly.
