5.1. Overview
5.1.1 Maintenance
WARNING!
Do not remove a failed component from the system until you have
a replacement on hand. If you remove a failed component without
replacing it, the internal airflow will be disrupted and the system
will overheat.
CAUTION!
1. Do not insert a controller module from other Galaxy
enclosures. A controller from another enclosure may have
acquired a system serial number from system EEPROM, and
could have used the serial number to generate a unique
controller ID. As the result, you may encounter SAN problems
with identical port names on multiple systems.
2. Do not use a PSU or cooling module from earlier Galaxy
series. They look similar. However, they may come with
cooling fans with different rotation speeds, and may not be
sufficient for your HDX4 models.
All of the following components can be replaced in case of failure:
1. Controller module
2. Memory module
3. CBM module
4. PSU modules
5. Cooling fan modules
6. Hard disk drives
