Replacing System Components
This section describes how to replace the components in the High-performance NAS
Platform. Follow the procedure if you are a qualified System Administrator, Network
Administrator, or Technician.
Note: PSUs and fan assemblies are the only hot-swappable components of a High-
performance NAS Platform. NIM, FSA, FSB, FSX, and SIM modules are not hot-
swappable components. See
Hitachi High-performance NAS Platform™," on page 37

Replacing a Hitachi High-performance NAS Platform
Module (Non-Upgrade)
This section describes how to replace a High-performance NAS Platform module with the
same type of module (a "like for like" replacement). For instructions on how to replace
modules to upgrade a High-performance NAS Platform, see
by Replacing Modules," on page
Caution: All power to the High-performance NAS Platform must be switched off
before replacing any modules.
1. Shut down the server, see
Hitachi High-performance NAS Platform™," on page 37
2. Verify that the power switches on both the PSUs are in the OFF position.
3. Unscrew the retaining screws (the screw is only a 1/4 turn) of the module. The
retaining screws are spring-loaded and remain in the module.
4. Remove the module by pulling and lifting the ejection levers outwards.
5. Slide the module carefully out of the enclosure.
6. Replace the module by sliding the new module in the correct position (refer to the
module position indicator) until it stops.
Note: Modules are 'keyed' only to fit into their correct slot. Therefore, do
not try and force a module into a different slot. The module position in the
chassis is indicated by the graphic in the bottom right hand corner of each
module.
