Module replacement
Except for the I/O module, all other DAS-300 E modules are hot-pluggable and redundant.
A module can be replaced whilst the DAS-300 E is running.
The following safety requirements must be observed when replacing a plug-in module:
z
Ensure that you have a replacement module of the same type before removing the
faulty plug-in module.
z
The DAS-300 E must never be operated with one or more unfitted bays for more than a
few minutes, since this may cause overheating of the DAS-300 E and thus power failure,
data loss and loss of warranty.
z
Ensure that you are electrostatically discharged (earthed) before you touch a plug-in
module. Wear suitable ESD shoes or a ground strap.
