Step 1: Powering Up the System
1. If the DigiCORA PC is running, switch it off.
Before you switch the DigiCORA PC on, make sure that an active
device (Ethernet switch or SPSxxx) is connected to RJ-45 (LAN)
connector. If the active device is SPSxxx, it must be running.
If no active device is connected to the DigiCORA PC, switch
DigiCORA off, connect the active device to RJ-45 (LAN)
connector, and switch DigiCORA PC on. If you use SPSxxx as the
active device, it must be switched on 3 minutes before switching
power on to DigiCORA PC.

RTE21 elevation unit.
