The components and boards associated with the NBR are sensitive to static discharges. Be sure to use an antistatic wrist strap and observe all static precautions during this procedure. Failure to do so could result in damage to the NBR.

1.Insert the SIMM between the connector teeth in the SIMM slot.

2.Pivot the SIMM back until it locks into the clips in the SIMM slot, and the SIMM holes fit over the SIMM slot posts.

3.2.5 Adding/Replacing EPIMs

This section contains procedures on how to add/replace an Ethernet Port Interface Module (EPIM) to upgrade or change the capabilities of your hub. See Figure 3-5. After installing your new EPIM, refer to appropriate EPIM sections in this chapter for connecting media types and to verify proper operation.
