Chapter 2 Hardware Components

2-1 Expansion Card Layout and Components

The AOC-SLG4-4X4T is a low-profile, PCIe x16 buffer expansion card that features an external NVMe connector for high-performance storage connectivity. This HBA card is built around a PCIe re-timer IC which is proven NVMe technology with optimum performance for increased bandwidth.
This AOC addresses the growing demand for increased data throughput and scalability requirements across enterprise-class Gen 4 JBOF platforms.
The following pages describe the components and settings for the AOC- SLG4-4X4T.

2-2 Major Components
The following are the major components that make up the AOC-SLG4-4X4T expansion card:

AOC-SLG4-4X4T Components

2-3 Connectors
NVMe Connectors
There is one NVMe connector on the expansion card, which provides a transfer rate speed of up to 16GB/s.

AOC-SLG4-4X4T Connector

Item| Description
1| MiniSAS HD Connector for PCIe x16

While the number of hosts can vary based on the configuration, in every configuration the cables between the JBOF and the hosts are usually connected from Port A (JBOF) to Port A (Host) and from Port B (JBOF) to Port B (Host). Looking at the L bracket from the outside, there is a clear marking on the end where Cable A should go (and Cable B goes in to the other port).
If two cables are plugged into the AOC, then all x16 lanes will be used. If only Cable A is connected, then it’s limited to x8. The table below lists supported cables.

Part Number	Cable Length
CBL-SAST-1035-1	1 meter
CBL-SAST-1036-1	2 meters

Chapter 3 Installation

3-1 Static-Sensitive Devices
Electrostatic Discharge (ESD) can damage electronic com ponents. To avoid damaging your expansion card, it is important to handle it very carefully. The following measures are generally sufficient to protect your equipment from ESD.
Precautions

Use a grounded wrist strap designed to prevent static discharge.
Touch a grounded metal object before removing the expansion card from the antistatic bag.
Handle the expansion card by its edges only; do not touch its components or peripheral chips.
Put the expansion card back into the antistatic bags when not in use.
For grounding purposes, make sure that your system chassis provides excellent conductivity between the power supply, the case, the mounting fasteners, and the expansion card.

Unpacking
The expansion card is shipped in antistatic packaging to avoid static damage. When unpacking your component, make sure you are static protected.
Note: To avoid damaging your components and to ensure proper installation, be sure to always connect the power cord last, and always remove it before adding, removing, or changing any hardware components.

3-2 Before Installation
To install the expansion card properly, follow the steps below.
Prior to Installation

Power down the system and unplug the power cord.
Use industry-standard anti-static equipment (such as gloves or wrist strap) and follow the precautions on page 3-1 to avoid damage caused by ESD.

3-3 Installing the Expansion Card

Once the system is fully powered down, remove the power cords from the rear of the power supply, and remove the system cover.
Verify that the expansion card is equipped with the correct PCIe slot bracket length for your system. AOC-SLG4-4X4T expansion cards include a low-profile PCIe bracket. However, if your system features full-height PCIe locations, replace the low-profile bracket with a full-height bracket.
Install the add-on card into a PCIe x16 slot on your motherboard and secure the bracket with the hardware provided.
Replace the system cover, plug in the power cord, and power up the system.
