Installing CBM (optional, 3012 & 3016 models only)
The CBM consists of a supercapacitor or battery backup unit (BBU) and flash backup
module (FBM). The CBM can sustain cache memory in the event of a power failure
or in the extremely unlikely event of both PSUs failing at the same time. The use of a
CBM is highly recommended in order to safeguard data integrity. The CBM is an
optional item for this system model and can be purchased from your system vendor.
The CBM has to be installed on the controller before rack-mounting the system.
NOTE
The CBM (BBU + FBM) will be pre-installed for you if you ordered it as a part of the
system. If you purchase the CBM afterwards as an upgrade component, please read
and follow the instructions in this section carefully.
3008 model is not equipped with a BBU or supercapacitor.
Supercapacitor Installation Notes
Please read the following sections on how to install the supercapacitor into the
controller. Always place the controller on a clean, static-free surface and hold the
controller only by its metal canister and never touch the circuit board or connector
pins.
Supercapacitor Installation Steps
1. Remove the controller first. Please refer to
the controller removed, loosen the three screws as shown in the picture. Keep
the three screws at a safe place.
2. Screw the three spacer bolts into the designated thread holes.
3. Place the charge board on top of the three spacer bolts, so the connector of
charge board and controller match. Push the charge board gently down to join
the connectors. Secure the charger board with
two
of the former removed three
screws.
