System Booting and Dumping
2.3. Booting the System
There are five types of boot operations:
• Port path load from the OS 1100 host
• Port path load from disk
• Boot from the integrated diskette
• Load from disk using configured load paths
• Load from host using configured load paths
Tell the DCP which type of boot to perform by using the LOAD switches on the DCP. The basic LOAD settings are described in Table 2-2.
Table 2-2. Basic load Settings
Setting Operation
All switches down (zeroes). Load from the integrated diskette (typically for troubleshooting or when a host is
leftmost switch up and port number in unavailable) .
other switches. load using designated port.
leftmost switch down and load path in
other switches. load using load path.
You can perform any of the boot operations by following this sequence:
1. 'furn on the equipment.
2. Insert the system diskette. The label should face either up, down, or to the right, depending on the DCP model.
3. Set the switches according to DCP type, as specified in Table 2-3.
Note: The position of any unspecified switch does not affect the boot process.
4. Set the LOAD switches. The number of LOAD switches varies according to the DCP type. In all cases, however, the switches represent binary number values where the DOWN position indicates a 0 value and UP indicates a 1. Set these switches as shown in Table 2-4.

6. Push either the SYSTEM RESET button or the PROGRAM LOAD button. Table 2-6 explains the differences between these buttons.
Notes:
1. The DCP/5 uses the same load switch philosophy as the other DCP models, but implements the switches through screen menu selections.
For more information on how to set the load switches on the DCP / 5, refer to the DCP / 5 Installation and Operations Reference Manual (UP-14133).
2. The DCP612,614,618,622, and 624 use the same load switch philosophy as the other DCP models, but implements the switches through a window on the Control Station.

2. Loads CP/OS's bootstrap' from boot diskette.
3. Dumps DCP memory and loads DCP/OS.
Push SYSTEM RESET for a boot to clear memory. Push PROGRAM LOAD for a dump of DCP memory. You can follow the progress of the load operation by watching the display lights on the DCP and by watching the system console.
Mode clear is issued by the partition's lOPs to the LMs on both system reset and program load (if that partition is of a
DCP/25,30,35,50,55,612,614,618,622, and 624 machines, and on program load for DCP/5,15 machines). The hardware clear is issued by the hardware to the LMs on system reset. This results in the following states (Table 2-6) for the various LM categories:
~m Booting and Dumpinl
operational still operational not operational not operational not operational loaded still loaded still loaded still loaded not loaded connected to not connected not co~nected not connected not connected partition's bus
Notes:
1. If the LM was not connected to the partition's bus at the time of the system reset or program load, the LM is not affected at all.

2. If the LM is not associated with the partition, the LM is not affected at all
For an initial download of the DCP from a host, you should determine the port number of the host channel or communications line. Enter this number into the LOAD switches and set the leftmost (0 position) switch to UP. You do not need to determine the port number if you created DOWNLOAD load path with @MONFIG.
Note: When you have completed booting the system, set the switches to the dump path that you want to use.
Caution
To dump OCP memory, press PROGRAM LOAD. Do not press SYSTEM RESET; this will clear memory.

2.3.1. Example: Booting a DCP/50
This example explains how to boot a DCP/50 by downloading the
software from an OS 1100 host. Assume that the host channel is on port number OE in the DCP/50.
1. Before downloading, prepare the host for the load. See the
Communications Delivery Installation Guide (7831 5645) for details on preparing the download file and configuring CMS 1100.
2. Ensure that the DCP/50 is powered on.
3. Insert the 3 lh-inch system diskette.
4. Set the MAINTENANCE switch to the NORMAL position (down).
5. Set the LOAD switches to 1000 1110 (port path, using port OE).
6. Push the SYSTEM RESET button.
Note: For more information on the DCP file transfer program, refer to Appendix. B.
2.3.2. Booting a Partition on a DCP600 Series
The DCP600 has either one or two partitions. The diskette for the top 10M (partition A) is labeled 'partition A', while the diskette for the middle 10M (partition B) is labeled 'partition B'.
This example explains how to boot a partition on a DCP600 series by downloading the software from an
as
1100 host. Assume that the host channel is on port number OE in the DCP600.1. Set the power switch at the rear of the control station to ON. The DCP Control window is displayed as shown below in Figure 2-1.
