- | ==== ==== | + | ==== Remove Dual Output Prevention from EL ==== |
+ | \\ | ||
+ | If you are using DOP (dual output prevention) in the Encoders, you need to turn this off. | ||
+ | \\ | ||
+ | \\ | ||
+ | {{ : | ||
+ | \\ | ||
+ | From the General tab on the Encoder, untick Dual Output Prevention. | ||
+ | \\ | ||
+ | \\ | ||
+ | In a 1+1 EL configuration, | ||
+ | \\ | ||
+ | \\ | ||
+ | This causes an issue because there is a short period of time where neither Encoder is outputting, While the time for this condition is very short, it is long enough that the active Mux will have no inputs from either Encoder, and the active Mux will switch to the backup. Disabling DOP on the Encoders will stop this happening. | ||

+ | ---- | ||
+ | ==== nCompass Changes ==== | ||
+ | \\ | ||
+ | There are a couple of things we need to change in nCompass. One is the criticality of an alarm and the other is a config file. | ||
+ | \\ | ||
+ | \\ | ||
+ | We know that if one of our output interfaces goes down, the ELs will switch, for this reason we need to change the criticality of an interface down alarm. If we do this and nothing else, if both interfaces go down, then we will NOT get an encoder switch, so we need to change an nCompass file. | ||
