•

Ethernet Port

All controller modules on the subsystems come with a single 10/100BasedT RJ-45 Ether-

net port. The Ethernet port is used for local or remote management through the network 

using the Bosch RAIDWatch GUI manager or Telnet protocol. 

•

COM Port 

All controller modules come with one RS-232C (audio jack) serial port. The serial port is 

used for local access to the system-embedded configuration utility over the included 

serial port cable. 

The controller module comes with a preinstalled 256MB capacity or above DDR RAM DIMM 

module and can support a larger capacity up to 2GB. The DIMM module is mounted in an eas-

ily accessible location on the controller board. However, when the DIMM module is being 

changed, the controller module must be removed from the subsystem chassis.  

The Li-ION battery backup unit (BBU) module sustains cache memory for days after a power 

failure. It is installed on the upper left corner of the controller module in the rear of subsystem 

chassis. Please refer to Section 3 Hardware Installation for installation details.

BBU Module

In accordance with international transportation regulations, the BBU module is only charged 

to between 35% and 45% of its total capacity when shipped. Therefore, when powering on the 

subsystem for the first time the BBU will begin to charge its batteries to their full capacity. It 

normally requires approximately twelve (12) hours for the battery to be fully charged. If the 

battery is not fully charged after twelve (12) hours (its LED is still flashing), there is a problem 

with the BBU module and you should contact your subsystem vendor immediately. While the 

battery is being charged, the LED on the BBU rear panel and the fifth LED on the controller 

module will flash.

You can check the status of the battery’s charge via Bosch RAIDWatch Manager or the firm-

ware utility screen.

This subsystems come with preset configurations for channel mode and channel ID settings, 

and should be sufficient for most applications.
