1 Introduction
ote: For the remainder of this document, issues that pertain to both the DS -3200 and DS -3400 units
will be identified as DS -3200/3400.
D-Link Systems, Inc.™ has identified an issue wherein the drive activity light is constantly illuminated
when using a Seagate Barracuda ES.2 1TB SATA-II hard drive (Seagate part number ST31000340 S).
This issue affects DS -3200/3400 units shipped before January 2008. Please review section 1.3 of this
document for a detailed description of how to determine if your system is in need of this resistor pack
update. If you determine that your system is affected, then please proceed to the step-by-step update guide
in Section 2.
1.1 Purpose
The purpose of this document is to communicate the steps required to identify affected DS -3200/3400
units shipped before January 2008. This document will include how to identify affected systems and the
steps required to fix the issue.
1.2 Scope
This document is an EC (Engineering Change otice) concerning the identification of affected DS -
3200/3400 units shipped before January 2008 and the installation of four resistor packs to fix the issue.
This EC relates to any DS -3200/3400 units shipped from D-Link before
January 2008.
This issue does not affect the functionality of the DS -3200/3400 unit, nor
does it affect the data storage functionality of the Seagate ST31000340 S 1TB
hard drive. The drive activity light simply remains illuminated at all times.
1.3 Identification of Affected Systems
DS -3200/3400 units shipped after January 2008 will be modified at the factory to contain the four resistor
packs described in this document. However, any units shipped before this date will need to be examined.
Definitive identification of affected DS -3200/3400 units will require two steps. For this procedure it is
highly recommended that the system be shut down and power cords removed to minimize the electrical
shock risk.
Please follow these steps for inspection:
Step 1) Shut down the DS -3200/3400 through your management GUI. Please follow the instructions in
your xStack Storage User’s Guide.
Step 2) In order to minimize electrical shock risk, remove the three power cords from your DS -3200/3400
unit’s power supply.

Step 3) Remove the two right-most drives from the enclosure as shown in figure 1.
Figure 1: Remove the two right-most drive trays
Step 4) Using a flashlight, examine the upper portion of the now visible chassis backplane PCB (Printed
Circuit Board) located at the rear of the space. You should see something similar to that found in figure 2.
Here you will see a revision number. If your backplane has revision 1.4 or later, then your system is up to
date and needs no changes. If your system has Revision 1.1, 1.2 or 1.3, then you will need to continue to
step 5. You may now reinsert the drive trays.

Step 5) Remove the top cover from the DS -3200/3400. Located in the middle of the chassis is the chassis
backplane as shown in figure 3.
Figure 3: Identifying the chassis backplane
Step 6) Located on the backplane are four 10-position headers labeled A1315, A0912, A0508 and
A0104. The labels themselves are extremely small and difficult to read. Please see figure 4 to identify
these headers. ote that the two right-most headers are made difficult to see because of the placement of
four (4) four-position Molex power connectors. (In order to better orient you to the position of these
jumpers, please see the bare backplane and identified headers shown in figure 5)

Step 7) If you see a jumper block installed on each of these four headers like that shown in Figure 6, then
you will need to proceed to Section 2 for instructions on installing the new resistor packs. If you see a
modified jumper like that found in figure 7, then your system has been modified with the necessary resistor
packs. You may close your unit’s cover and return to normal operation.

2 Installing the Resistor Packs
If you have followed the steps outlined in Section 1.3 and determined that you need to install the resistor
pack modification, then please contact D-Link or your reseller to obtain the four (4) necessary resistor
packs. These resistor packs will take the place of each of the four jumpers found on the four 10-position
headers labeled A1315, A0912, A0508 and A0104.
Step 1) Shut down the DS -3200/3400 through your management GUI. Please follow the instructions in
your xStack Storage User’s Guide.
Step 2) In order to minimize electrical shock risk, remove the three power cords from your DS -3200/3400
unit’s power supply.
Step 3) Please remove the cover from your DS -3200/3400 to gain access to the chassis backplane PCB.
The backplane is identified in figure 3.
Step 4) Identify the four 10-position headers as shown in figures 4 & 5. The two right-most headers are
blocked by the power connectors. Remove the two (2) Molex power connectors labeled C 4 and C 7 to
gain easier access to the two (2) 10-position jumpers found below them. Please see figure 8 for details.

Step 6) For each 10-position header, you must remove the 4-position jumper block as seen in figure 6. You
will then see an empty 10-position header like that shown in figure 9. The top-right pin is removed and
will provide a guide for installation of the new resistor pack.
Figure 9: The empty 10-position header
Step 7) Familiarize yourself with the resistor pack. ote that two of the positions are empty as seen in
figure 10. Also be aware that one of the holes on the connector has been blocked as shown in figure 11.
This blocked hole will need to match with the missing pin shown in figure 9.

Step 8) Carefully orient the resistor pack over the 10-position header, making sure the keyed hole matches
the missing pin on the header. Press the resistor pack inwards until it is firmly seated. Figures 12 & 13
will give you a guide to what it will look like.
