  • Page 88 Chapter 5: Subsystem Maintenance and Upgrading Figure 5-8: Removing the BBU Step 2. Install the replacement BBU. Align the BBU with the slot, and then gently push the BBU into the slot. When you feel the contact resistance, use slightly more force for the back-end connector to mate with the backplane.

    Before you install a replacement PSU, be sure that it has the same warning text on its extraction handle as that shown on the handle of a remaining PSU. Double-check to avoid mixing a similar yet different PSU of another Galaxy series. To replace a PSU, please follow these steps: Step 1.
  • Page 91 Galaxy GHDXS2-1430R-16F4D Installation and Hardware Reference Manual Figure 5-12: Removing the PSU Retention Screw Step 4. Remove the PSU by grabbing the extraction handle and pulling the handle upwards. The extraction handle should gracefully disconnect the PSU from the backplane connectors.
  • Page 92 Chapter 5: Subsystem Maintenance and Upgrading WARNING! When a PSU is removed from the chassis, the cooling module is also removed from the chassis. It is recommended that the replacement procedure is completed in less than five (5) minutes to prevent the subsystem from overheating. Step 7.

  • Page 93: Cooling Module Maintenance

    Although the cooling modules are fully redundant, it is not advisable to run the Galaxy subsystem with fans in a single PSU module for an extended period of time. If the cooling fans in the only remaining module fail, the subsystem will quickly overheat.

    Chapter 5: Subsystem Maintenance and Upgrading audible alarm, the firmware utility, the RAIDWatch manager software, or the Configuration Client utility can notify you. Immediate replacement: Once you are notified that a cooling module has failed, it should be replaced as soon as possible. A failed cooling module should only be removed from the subsystem when you have a replacement immediately available.
