In the panel lineup overview, a green square indicates a healthy state and a red
triangle the states that require operator’s attention.
Table 6: Status icons
Status icon Description
Normal relay status
The relay has alarms or some other state that requires oper-
ator’s attention.
Connection to relay is lost or the relay is not trusted.
Physical Home and virtual Home button indications behave identically although the
physical Home button shows a combination of home buttons for each connected
relay. When relays have different statuses, the physical Home button shows the
status with the highest priority.
