Preface

Returning Merchandise for Service

A receipt or copy of your invoice marked with the date of purchase is required be-

fore any warranty service will be rendered. You can obtain service by calling your

vendor for a Returned Merchandise Authorization (RMA) number. When returning

to the manufacturer, the RMA number should be prominently displayed on the

outside of the shipping carton, and mailed prepaid or hand-carried. Shipping and

handling charges will be applied for all orders that must be mailed when service

is complete.

For faster service, RMA authorizations may be requested online (http://www.super-

micro.com/support/rma/).

Whenever possible, repack the backplane in the original Supermicro box, using the

original packaging materials. If these are no longer available, be sure to pack the

backplane in an anti-static bag and inside the box. Make sure that there is enough

packaging material surrounding the backplane so that it does not become damaged

during shipping.

This warranty only covers normal consumer use and does not cover damages in-

curred in shipping or from failure due to the alteration, misuse, abuse or improper

maintenance of products.

Duringthewarrantyperiod,contactyourdistributorrstforanyproductproblems.

Chapter 1: Safety Guidelines

Chapter 1

Safety Guidelines

To avoid personal injury and property damage, carefully follow all the safety steps

listed below when accessing your system or handling the components.

1-1 ESD Safety Guidelines

Electrostatic Discharge (ESD) can damage electronic com ponents. To prevent dam-

age to your system, it is important to handle it very carefully. The following measures

are generally sucient to protect your equipment from ESD.

• Use a grounded wrist strap designed to prevent static discharge.

• Touch a grounded metal object before removing a component from the antistatic

bag.

• Handle the backplane by its edges only; do not touch its components, peripheral

chips, memory modules, or gold contacts.

• When handling chips or modules, avoid touching their pins.

• Put the card and peripherals back into their antistatic bags when not in use.

1-2 General Safety Guidelines

• Always disconnect power cables before installing or removing any components

from the computer, including the backplane.

• Disconnect the power cable before installing or removing any cables from the

backplane.

• Make sure that the backplane is securely and properly installed on the mother-

board to prevent damage to the system due to power shortage.

#7. - 8. SAS Ports

The SAS ports are used to connect the

SAS or SATA drive cables CBL-SAST-0532

to an HBA card inserted in a PCIe slot on

motherboard X11DAi-N. The 2 ports are

designated JSM0, for drives at SAS #0-#3,

and JSM1, for drives at SAS #4-#7 (see

section 2-4 for SAS drive locations). Each

port is also compatible with SATA drives.

However, mixing SAS and SATA drives in

the same enclosure is not recommended.

#1. CPLD Chip

The CPLD is an enclosure management

chip that supports the SGPIO and LED

management.

#3. - 6. NVMe Connectors

The NVMe ports are used to connect the

NVMe drive cables. To congure 2 NVMe

drives, OCuLink cables CBL-SAST-0820

should be used to connect ports CN0 and

CN1 to NVMe slots 1 and 2 on motherboard

X11DAi-N. To congure 4 NVMe drives,

OCuLink cables CBL-SAST-0820 should

be used to connect all 4 ports to four corre-

sponding ports on add-on card AOC-SLG3-

4E4T in slot 3 of motherboard X11DAi-N

and connected to the motherboard's NVMe

I2C2 header with cable CBL-CDAT-0674.

Figure 2-2. Front Jumpers

Explanation of Jumpers

To modify the operation of the backplane,

jumpers can be used to choose between

optional settings. Jumpers create shorts

between two pins to change the function

of the connector. Pin 1 is identied with

a square solder pad on the printed circuit

board.

Note: On two pin jumpers, "Closed" means

the jumper is on and "Open" means the

jumperiso󰀨thepins.
