Chapter 1. Introducing the System

6C4 and Model 6E4. The Model 6C4 is a rack mount system and the Model 6E4 is a
deskside system.
System Features
Bus Architecture
Four PCI slots are available. Slots numbered 3 and 4 are 64-bit capable at 133 MHz,
3.3 volts. Use these slots with PCI adapters that demand high performance. Slots
numbered 1 and 2 are 64-bit capable at 66 MHz, 3.3 volts. Use these slots with PCI
adapters that do not demand high performance. All slots are capable of running either
64-bit or 32-bit adapters. However, a 32-bit adapter operates in a 32-bit mode and
shows no performance advantage while running in a 64-bit slot. The following
illustration shows the PCI Adapter Slot locations when viewing from the rear of the
system.
Processors
v One and two-way cards with POWER4 1.0 GHz microprocessors.
Note: Only a single 1-way card is allowed per server at one time; therefore, a 3-way
configuration is unavailable.
v An upgrade from a 1-way (FC 5131) to a 2-way (FC 5132) is available by feature
conversion.
v 32 MB L3 cache per-processor card
