1. Take a photo of the existing ME3400 that shows the current ports and cables being used. This can help if troubleshooting is necessary.
   
   
2. Trace each cable plugged into the ME3400 to its origin and label it accordingly. Put a "LAN" label on the cable(s) that go to your network (i.e. firewall, switch, patch panel, etc.). Put a "WAN" label on the cable that goes to the Internet (i.e. BadgerNet 3, Charter, dark fiber, etc.). Note: BadgerNet Connections often connect to a Juniper device. Charter or other provider's devices usually have a prominent "Owned By" label on them.
   
   
3. Label each fiber-optic strand on your ME3400 indicating Transmit ( T or → ← ) or Receive ( R or ← → ). See photo in Figure 2 below for guidance. Note: you can skip this step for any copper cables that are connected to the ME3400.

      Figure 2
      The top optic has a patch cable with permanent marker arrows drawn on to document polarity.

      
      NOTE: The Transmit connector is on the left and Receive on the right when the top of the SFP's handle is closed and facing upward towards you (such as when plugged into an ME3400). FlexOptix optics have a small triangle on the top of each port indicating light direction.

1. While the ME3400 is still connected, go to a hard-wired computer inside your network, and run a bandwidth test using: fast.com and record the results.
   
   
2. Disconnect the ME3400 network cables and connect them to the ASR-920 as illustrated in Figures 3 and 4 below. Figure 4 identifies the standard WAN and LAN port assignments. Figure 5 can help you identify ASR-920 port numbering.

      Figure 4 - WiscNet ASR-920 Standard Configuration
      PRIMARY
      CPE TYPE	Outside WAN Connections	Internal LAN Connections
      Cisco ME3400E (ME3400-2-CS)	2 Copper or SFP	1 Copper or SFP
      	↓	↓
      Cisco ASR 920 (ASR920-2G-4-10G)	Port 3 (SFP/SFP+)	Port 2 (SFP/SFP+)

      
      

      Note
      Port 2 on the ASR-920 is in the BOTTOM LEFT position, and Port 3 is in TOP LEFT position. Please see Figure 5. Port 2 is "upside down" so TRANSMIT is on the RIGHT and RECEIVE is on the LEFT.

3. The two triangular status lights above port 2 and below port 3 will change to green after a few seconds when they're linked.
   1. Note you may see other status lights flashing red lights on the ASR-920 during this process. Please ignore them for now.
      
      
4. Check your Internet connection to see if it is working.
   1. If you can access the Internet, proceed to the Post Installation Instructions.
   2. If you cannot access the Internet, refer to the Troubleshooting section.

If you're performing the upgrade on your own during business hours you can contact WiscNet to assist with troubleshooting by calling 608-442-6761 x2.  If not performing the upgrade during business hours, please fallback to the ME3400 to restore service (see below) and contact WiscNet support during the next available business hours.

ASR-920 boot time

Allow sufficient boot time – these devices can be quite slow to fully initialize at boot up.  Please allow at least 20 minutes for ASR-920 and 15 minutes for ME3400 (in the event of a failback)
