Overview
This document provides information to recyclers about how to disaasemble the UCS S3260 Storage Server
printed circuit board assembly (PCBA) to comply with ewaste and eco design requiements for Commission
Regulation (EU) 2019/424.
This document is an addendum to the Cisco UCS S3260 Storage Server Chassis Installation and Service
Guide https://www.cisco.com/c/dam/en/us/td/docs/unified_computing/ucs/s/hw/S3260/installb/S3260.pdf

Considerations for Battery Replacement
This chapter contains the following topic:
•Considerations for Battery Recycling, on page 3
Considerations for Battery Recycling
The following additional text supplements the information about replacing the Real Time Clock battery in
the Cisco UCS S3260 Storage Server.
For inforamtion about the RTC battery and battery installation and replacement procedures, see "Replacing
an RTC Battery Inside the Server Node" in the Cisco UCS S3260 Storage Server Chassis Installation and
Service Guide. Go to https://www.cisco.com/c/dam/en/us/td/docs/unified_computing/ucs/s/hw/S3260/installb/
S3260.pdf.
Recyclers: Do not shred the battery! Make sure you dispose of the battery according to appropriate regulations
for your country or locale.
Warning
The real-time clock (RTC) battery retains system settings when the server is disconnected from power. The
battery type is CR2032. Cisco supports the industry-standard CR2032 battery, which can be purchased from
most electronic stores.

CHAPTER 3
Recycling the PCB Assembly (PCBA)
This chapter contains the following topic:
•Recycling the PCB Assembly (PCBA), on page 5
Recycling the PCB Assembly (PCBA)
The PCBA is secured to the bottom of the server chassis. To recycle the PCBA, you will need to remove some
components from the server. The assemblies and subassemblies are secured to the chassis and held together
by M3x0.5mm screws.
Before you begin
For Recyclers Only! This procedure is not a standard field-service option. This procedure is for recyclers
who will be reclaiming the electronics for proper disposal to comply with local eco design and e-waste
regulations.
Note
To remove the printed circuit board assembly (PCBA), the following requirements must be met:
• The server must be disconnected from facility power. See "Shutting Down and Powering Off the S3260
System" in the Cisco UCS S3260 Storage Server Chassis Installation and Service Guide. Go to
https://www.cisco.com/c/dam/en/us/td/docs/unified_computing/ucs/s/hw/S3260/installb/S3260.pdf.
• The server must be removed from the equipment rack.
• The server's top cover must be removed. See in the Cisco UCS S3260 Storage Server Chassis Installation
and Service Guide. Go to https://www.cisco.com/c/dam/en/us/td/docs/unified_computing/ucs/s/hw/S3260/
installb/S3260.pdf.
• All drives in the drive cage should be removed. If they are present, remove them now. See "Replacing
Internal Drives" in the Cisco UCS S3260 Storage Server Chassis Installation and Service Guide. Go to
https://www.cisco.com/c/dam/en/us/td/docs/unified_computing/ucs/s/hw/S3260/installb/S3260.pdf.
Step 1 Remove the mouting screws from the left and right exterior sides of the chassis.
The following figure shows these screws.

Step 2 Remove the SSD backplane cables.
a) Using a screwdriver, rotate each of the top rear cover screws counter-clockwise until it disengages.
b) Remove the top rear cover.
The following image shows the location of the rear top cover screws.

c) Reach down to grasp the SSD backplane cable connectors, then disconnect the cables from the SSD backplane and
Midplane assembly.
d) Cut the cable tie that secures the SSD backplane cables to the chassis.

Step 3 Remove the cover plate.
a) Open the fan compartment doors by pushing the latches inward toward each other.
b) Using a screwdriver, rotate each of the Midplane assembly screws counter-clockwise until it disengages.
c) Grasp the cover and remove it by hand.
The following illustration shows the location of the screws.

Step 4 Remove the Midplane PCBA.
a) Remove all the fans (if present).
b) Remove the fan cage.
c) Disconnect the sensor connector from the motherboard.
d) Locate the cable tie on the interior chassis wall and cut the tie so that the cables are no longer attached to the chassis.
e) Lift the Midplane assembly straight up to disconnect it from its sockets and remove it from the chassis.
The following image shows the locations of these components.

Step 5 Disassemble the Midplane PCBA.
a) Using a standard screwdriver, gently pry up the Bus Bar modules at each connector until you can remove them by
hand.
b) Using a screwdriver, rotate each of the screws counter-clockwise until it disengages.
c) Grasp the midplane bracket and remove it by hand.
d) Separate the Midplane PCBA from the midplane bracket by hand.
The following image shows the screws and components.

Step 6 Remove the drive cage mounting screws from the front of the chassis.
The following illustration shows these screws.

Step 7 Open the double doors for the drive cage.
Step 8 Remove the drive cage.
a) Disconnect the motherboard sensor connector from the motherboard by hand.
b) Using a long standard screwdriver, disconnect the ribbon cable from the each of the FPC motherboard connectors
by swiping the connector towards the chassis front panel.
The FPC connectors have small hinges that open by pivoting toward the chassis front panel. When a
connector opens, its ribbon cable is disconnected. The ribbon cable is attached to the inside of the drive
cage, which can add resistance when you remove the drive cage.
Note
c) Using a screwdriver, rotate each of the screws counter-clockwise until it disengages.
d) Lift the drive cage out of the chassis.
If the ribbon cables for the FPC connectors cause resistance when you lift the drive cage, pull the cables to detach
them from the drive cage.
The following image shows the screws and components.
