1 Chapter 1. General description The IBM® ^™ pSeries™ 610 Models 6C1 and 6E1 (referred to hereafter as the Model 6C1 and Model 6E1) are members of the 64-bit family of symmetric multiprocessing (SMP) UNIX servers from IBM and use state-of-the-art, 64-bit, copper-based, POWER3-II microprocessors. The Model 6C1 (product number 7028-6C1) is a rack-mounted server, the Model 6E1 (7028-6E1) is a tower server.
for keyboard, mouse, one parallel, and three serial. Only the rack-mounted Model 6C1 has serial port one accessible from an RJ48 connection on front as well as the standard 9 pin port on the rear of the system. When one port is used, the other is disabled. The serial port 1, accessible on front, has a higher priority than serial port 1 on the rear. Note: If you want to attach a 25-pin serial cable, you need to order the Serial Port Converter Cable, 9-Pin to 25-Pin (# 3925).
The Models 6C1 and 6E1 are the first IBM UNIX servers that contain built-in Light Path Diagnostics. This technology provides LEDs physically located on key system components, assisting in quick diagnosis and resolution of problems, should they arise. Please refer to “Light Path diagnostics” on page 21 to get detailed information. 1.2 Physical package Figure 1-1 on page 3 shows the package layout for the Model 6C1, and Figure 1-2 on page 4 shows the same for the Model 6E1.
Figure 1-2 pSeries 610 Model 6E1 - package layout 1.3 Enterprise racks The following description provides an overview of racks available from IBM in which the Model 6C1 can be mounted. At the time of writing, no feature is available to convert a tower model to a rack mount model. Check with your IBM representative to determine the availability of this feature. The Enterprise Rack Models T00 and T42 are 19-inch wide racks for general use with pSeries and RS/6000 rack-based or rack drawer based systems.
Note: You can get the latest available IBM ^ pSeries Specifications For Installations in A Non-pSeries Rack or Cabinet document from this IBM internal location: http://wwas.raleigh.ibm.com/safety/racks.pdf 1.3.1 IBM RS/6000 7014 Model T00 Enterprise Rack The 1.8 m (71 inches) Model T00 is compatible with past and present pSeries and RS/6000 racks, and is designed for use in all situations that have previously used the older rack models R00 and S00.
you need to remove the server from the rack at a later time. If you are not able to find them at a later time, you will need to order two of part number 09N7997. A Model 6C1 is 5 U in height, so a maximum of seven Model 6C1s fit in a T00 rack, or you can put eight Model 6C1s in a T42 rack. Each Model 6C1 is shipped with a rack mounting template, which helps you to easily place the cage nuts in the correct position in a rack. 1.3.
1.3.6 Cable management arm The Model 6C1 is shipped by default with a cable management arm. You can route all cables through the cable management arm, attaching the cables to the arm with the hook and loop fastener strips provided. The wraps are provided for additional cable management. Figure 1-3 shows the cable management arm. As the drawer is moved on its rails into the service position, the arms expand or collapse, actively managing the cables.

2 Chapter 2. Architecture and technical overview The following sections provide more detailed information about the architecture of the Models 6C1 and 6E1. Figure 2-1 shows the high level system block diagram of both models.

2.1 Processor and cache The IBM® ^ ™ pSeries™ 610 Models 6C1 and 6E1 have two processor card slots and can accommodate two different processor cards, a 1-way 375 MHz or a 1-way 450 MHz. Note that slot 1 must have a processor card installed for normal operation. If your system unit uses two processor cards, both processor cards must be of the same clock speed. Note: Installing a processor card into your system unit may require updating the firmware.
2.1.3 Copper and CMOS technology Copper is a superior conductor of electricity, making it possible to shrink electronic devices even further while increasing performance. It has less resistance than aluminum and, therefore, allows designs that transmit electrical signals faster. However, it does not mix as well with silicon, the base material of semiconductor chips.

2.2.1 Memory boot time deconfiguration Memory boot time deconfiguration is a function implemented in the service processor firmware for removing a memory segment or DIMM from the system configuration at boot time. The objective is to minimize system failures or data integrity exposure due to faulty memory hardware. The memory segment or DIMM that is deconfigured remains offline for subsequent reboots until the faulty memory hardware is replaced.
Note: Please refer to the PCI Adapter Placement Reference, SA38-0538, to find detailed information on where to plug in your adapters. Hot plug capabilities for PCI adapters are not supported on the Models 6C1 and 6E1. However, they are available within the IBM ^ pSeries and RS/6000 product line.
Note: On the Model 6C1 the SCSI slots of the hot swap six pack are numbered from 1 to 6, right to left. On the model 6E1 they are numbered 1 to 6, top to bottom. Table 2-2 give you detailed information about how you can connect internal SCSI devices to your system. Table 2-2 SCSI cable configurations Configuration options, a combination of: SCSI devices in media bay 0 or 1. Zero up to six hot swap disk drives to be installed in the six pack enclosure.
2.5.1 Boot options and limitations Information about boot options is included in the subsequent sections.
2.6 Security To prevent the system from unauthorized booting from CD-ROM, you can set up a power-on-password (POP) or a privileged-access password (PAP). In order to protect the system from unauthorized users removing the battery to delete POP and PAP, you can lock the Model 6E1 with a key lock on the front cover, which protects your side cover as well as the hot-swap disk drives and other media bays from unauthorized access.
3 Chapter 3. Availability, investment protection, and expansion The following sections provide more detailed information about configurations, upgrades, and design features that will help you lower your cost of ownership. 3.1 High availability solution For even greater availability and reliability, the Models 6C1 and 6E1 also support IBM® High Availability Cluster Multiprocessing (HACMP) software, the leading UNIX disaster recovery clustering solution.
mode to uniprocessor mode with unpredictable results. Therefore, it could not be used in the Models 6C1 and 6E1. Capacity Upgrade on Demand (CUoD) Capacity Upgrade on Demand (CUoD) is a new feature that allows you to have inactive processors installed on your system, which can be made active quickly and as easily as your business needs require.
3.2.1 Light Path diagnostics The Models 6C1 and 6E1 are the first IBM UNIX servers that implement Light Path diagnostics technology. Light Path LEDs provide an obvious and intuitive means to positively identify the failing Field Replaceable Unit (FRU) through a path of light emitting points, starting on the exterior of the system (System Attention LED), located on the front of the system (also on the rear of rack mounted 6C1), and ending with a LED at or near the failing FRU.
You can access the indicator panel without any tools. The panel provides enough information to identify the area that needs attention. The panel contains a group of amber LEDs that indicate which functional area of the system is experiencing the fault (such as Power, Processor cards, Memory, or Fans).
Machine Check Interrupt. Operating System Hang (Surveillance Failure). Operating System Failure. Surveillance The service processor, if enabled through service processor setup parameters, performs a surveillance of AIX through a heartbeat mechanism. If there is no heartbeat within the time-out period, the service processor does the following: Creates a system reset to allow an AIX dump to occur.
Serial port snoop You can use the serial port snooping at any point after the system is booted to AIX, whenever the configured reset string is typed on the main console. The system uses the service processor reboot policy to restart. This action causes an early power off warning (EPOW) to be logged, and also an AIX dump to be created if the machine is at an AIX prompt, with AIX in such a state that it can respond. If AIX cannot respond, the EPOW record is created, rather than the AIX dump.
3.2.5 Hot plug task The hot plug task provides software function for those devices that support hot-plug or hot-swap capability. This includes PCI adapters, SCSI devices, and some RAID devices. Use diag -T identifyRemove to invoke the hot plug task manager.
SCSI hot swap manager functions Description Configure added or replaced devices After a slot is selected, the device populating that slot is unconfigured. Then the power is removed from that slot. If the unconfigure operation fails, it is possible that the device is in use by another application. In this case, the customer or system administrator must be notified to quiesce the device. If the Unconfigure operation is successful, the visual indicator for the selected slot is set to the Remove state.
