NOTICE!

This subsystems come with preset configurations for channel mode and channel ID settings, and should be sufficient for most applications.

•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.

DIMM Module

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.

2.3.4Battery Backup Unit

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.

Fig. 2.11 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.
