Recycling Chassis Components

This chapter contains the following topics:

Recycling Chassis Components

The Cisco UCS XE9305 Chassis and some of its nodes have printed circuit boards (PCBs) and other components that must be disposed of in compliance with your appropriate recycling and ewaste regulations, including, but not limited to Commission Regulation (EU) 2019/424.

The following procedures are not standard field-service options. They should be used only by certified or approved recyclers.

Recycling Batteries

The Cisco UCS XE9305 Chassis has two batteries that are included when the product is shipped.

Each battery is a coin-style lithium battery (CR2032) that retains system settings when the chassis is disconnected from power.

  • One battery is inside the left mounting bracket. This battery is called the chassis battery, and it is mounted on the LED board.

  • One battery is on the eCMC module. This battery is called the eCMC battery, and it is mounted directly on the module's motherboard.

Each battery sits in a clip that is accessible after removing some components. After components are removed, you can remove the battery with your fingers.

The battery is not a FRU, so remove it for recycling purposes only.


Warning

Recyclers: Do not shred the battery! Make sure you dispose of the battery according to appropriate regulations for your country or locale.

Use the following tasks to recycle the batteries.

Recycling the Chassis Battery

The Cisco UCS XE9305 modular system has a chassis battery built into the left mounting bracket. This component contains latch and LED board, and the chassis battery is located on the LED board.

Recycling DIMMs

The Cisco UCS XE130c Compute Node contains DIMM memory modules that must be recycled in compliance with your local ewaste and recycling regulations.

DIMMs are arranged in banks connected to the node's CPU. Each DIMM module occupies one slot in the DIMM bank, and the DIMM module is held in place by connector latches.

Use the following tasks to recycle the DIMM modules.

Recycling the Compute Node DIMM Modules

DIMM modules must be recycled in compliance with your local ewaste and recycling laws. DIMMs are installed in slots on the compute node and held in place by connector latches.

Use this procedure to recycle DIMM memory modules.

Before you begin

Recycling Power Supplies

The Cisco UCS XE9305 Chassis features two hot-swappable 2400 W Titanium AC power supply units (PSUs) providing N+N redundancy. The PSUs are accessible from the front of the chassis.

PSUs must be recycled in compliance with your local ewaste and recycling regulations.

Recycling PSUs is a tool less process. You do not need to power down the chassis to recycle the PSUs, because when you remove enough PSUs, the chassis power management features will begin gracefully powering down the Cisco UCS XE9305 Modular System. However, it is a best practice to power down the chassis before recycling power supplies.

Recycling Power Supplies

The chassis has two PSUs that are accessible from the front of the chassis. You do not need any tools to recycle the power supplies.

Procedure

Step 1

Remove the PSUs

Go to Removing Power Supply Units.

Step 2

Recycle the PSUs in compliance with your local ewaste and recycling regulations.

Recycling CPUs

Each Cisco UCS XE130c Compute Node contains a CPU that is connected to, and sits between, DIMM memory banks. The CPU is accessible by removing each compute node.

To recycle the CPU, you will need to remove the CPU's heatsink and disconnect the CPU from the socket. The CPU is not field-serviceable or easliy replaceable, so recycling it is a destructive process.

Recycling the XE130c Compute Node CPU

Each XE130c Compute Node has a CPU that must be recycled in compliance with your local ewaste and recycling regulations.

To recycle the CPU, you will need to remove the CPU's heatsink and disconnect the CPU from the socket. Each compute node features a BGA (Ball Grid Array) type CPU, which requires a hot air gun, soldering gun, or other equipment to heat the CPU and desolder it from the motherboard.

Before you begin

Gather a #2 Phillips (cross head) screwdriver.

A soldering gun, hot air gun, or similar tool to heat the connections between the CPU and the motherboard.
