  • Page 22 Removing a Port Adapter When only one port adapter is installed on a VIP2, a blank port adapter must fill the empty slot. This allows the VIP2 and router chassis to conform to electromagnetic interference (EMI) emissions requirements, and encourages air to flow through the chassis properly. If you plan to install a new port adapter, you must first remove the blank port adapter.
  • Page 23 Figure 3-4 Step 7 If you removed a port adapter, place it in an antistatic container for safe storage or shipment back to the factory. If you removed a blank port adapter, no special handling is required; however, store the blank port adapter for potential future use. This completes the procedure for removing a new port adapter on a VIP2.
