Installation
5. Insert the assembly and lock it in place by pushing up the securing latches
on the two circuit packs. (It is normal for the two circuit packs to feel
loosely connected to each other. This is to allow some give when you are
seating them into the two slots of the backplane.) If the switch is powered
on, the DEFINITY LAN Gateway system will boot automatically.
NOTE:
If the switch is not powered on, wait until it is and then proceed to
Step 6.
6. As the DEFINITY LAN Gateway system comes up, watch the Liquid
Crystal Display (LCD) on the faceplate (see Figure 2-5). The LCD
identifies the DEFINITY LAN Gateway states and alarms.
