Removing a Battery from an EX8208 Switch for Recycling
The EX8208 switch contains a CR2032
A base configuration switch has one SRE module, and a redundant configuration switch has two modules installed. Before recycling an SRE module or the switch chassis, remove the battery from each SRE module for battery recycling.
Before you begin to remove the battery:
•Power off the switch or take the SRE module offline. If only one SRE module is installed in a
Ensure that you have the following parts and tools available:
•Phillips (+) screwdriver, number 2
•Electrostatic discharge (ESD) grounding strap
To remove the battery from an SRE module in the switch (see Figure 95 on page 234):
1.Attach the antistatic discharge (ESD) grounding strap to your bare wrist, and connect the strap to one of the ESD points on the chassis.
2.Locate the SRE module in the switch chassis.
3.With the screwdriver, loosen the captive screws on each side of the SRE module by turning them counterclockwise until they are completely unseated.
4.Pull both ejector levers outwards, away from the faceplate of the SRE module, until they go no further. This action causes the module to slide slightly out of the chassis.
5.Grasp the ejector levers, and pull the SRE module out to about halfway.
6.Place one hand underneath the module to support it, and slide it completely out of the chassis.
7.Locate the
8.With your finger, pry the battery out of its socket.
9.If you are recycling the entire chassis of a redundant configuration, repeat Steps 2 through 8 for the second SRE module.
10.Recycle the battery or batteries as required.
