Inside the server

Cooling fans
The server contains several cooling fans for the HDDs, power supply, system
motherboard, and CPUs. The server may be fitted with a redundant fan module
so that, if one unit fails, the remaining fan module permits the system to remain
in operation.
A faulty cooling fan is indicated by a flashing FAULT indicator & LCD
Display. See “Server status indicators (lamps)” on page 11 for details.
Prompt repair of the failed unit is necessary. The failure of another cooling fan
could result in damage to components and the loss of important programs and
data.
To replace a cooling fan module, see “Fan module installation/removal” on
page 37.
CAUTION: Toshiba recommends that you call an authorized Magnia
service provider. Installing or replacing the fan drawer requires special
techniques and knowledge.
CPU slots
The CPU banks allow easy addition and replacement of the CPU modules. To
install or upgrade a CPU, see “Adding a CPU” on page 43.
SMC board
This is a secondary board. It controls the Power ON/OFF, monitors the power
supply units and FANs, and controls the LCD and LEDs.
RTC battery
The Real Time Clock (RTC) battery maintains the time of day. It may also
provide timing signals for timesharing operations. A RTC battery is on the
motherboard. To replace the battery, see “Replacing the motherboard battery”
on page 48.
Memory banks
There are four memory banks in the server. Each memory bank has four slots
for a total of sixteen memory slots that allow you to replace and upgrade the
server’s Random Access Memory (RAM). To replace or upgrade memory
modules, see “Adding memory” on page 39.
