Unpack the BRIM-W6 as follows:
1. Remove the shipping box material covering the BRIM-W6.
2. Carefully remove the module from the shipping box. Leave the
module in its non-conductive bag until you are ready to install.
3. Attach the disposable grounding strap to your wrist and to a proper
ground (refer to the instructions outlined on the grounding strap
package).
4. After removing the module from its non-conductive bag, visually
inspect the device. If you notice any signs of damage, contact
Cabletron Systems Technical Support immediately.
The BRIM-W6 and the host hub are sensitive to static
discharges. Use a grounding strap and observe all static
precautions during this procedure. Failure to do so could
result in damage to the BRIM-W6 or the host hub.
