Gateway ALR 7200 - Manual (Page 35)

Components 23
• One RJ-45 Ethernet connector with two LED indicators. The green
LED indicates a communication link has been established with the
network and the yellow indicator shows that the communication is
occurring at 100 Mbps.
Processor subsystem
The system board supports as many as two processors (CPUs). The board
provides several additional connectors for supporting components, as
described in the following paragraphs.
CPUs and CPU slots
Depending on the model, the system is equipped with one Intel Pentium
®
II
processor with 512-KB ECC L2 cache, integrated into a Single Edge
Contact (SEC) cartridge.
The system’s SMP design supports up to two processors and is Intel MP
Specification v1.1 and 1.4 compliant.
CPU fan connectors
The CPU fan connectors provide power for the fans mounted on the
processor heatsinks. These fans cool the processors and prevent
overheating. Note that not all processor heatsink have or need fans. If the
processor heatsink includes a fan, connect it to the correct fan connector.
Voltage regulator modules
Each CPU must have a dedicated voltage regulator module (VRM) which
adjusts the voltage supplied to the CPU. The VRM for the first CPU (CPU
1) is embedded on the system board.
Memory
The system comes standard with 64-MB of Error Checking and Correcting
(ECC) RAM. System RAM is expandable up to 1-GB using ECC 60-ns
72-bit synchronous DRAM (SDRAM) DIMMs (4 DIMM sockets).
