Memory Subsystem Configuration - HP 3000 Series Handbook

For HP Internal Use Only
The switchbox performs a function similar to that of the Access Port "Enable Remote"
command.
If the switchbox is set to position "A", a session through the modem is created through port
2 on the local system. This is the normal "session access" to the system for Response Center
personnel and end-users for remote system administration.
If the switch box is set to position "B", access through the modem is to port 7 on the local
system. The local system must be configured with the remote console permanently enabled
(AP ER command). This setup allows access to the console port and is considered the
"remote console" connection that is traditionally provided by the Access Port.
Note that the local console port is left open for local console usage as needed. Onsite support
by authorized service providers may be performed through the attachment of a terminal
device to port 0.
Hewlett-Packard Customer Engineers (CEs) in Japan use the HP Omnibook 300 PC with an
HP terminal emulator and a 9-pin to 25-pin serial cable as a "service console". Users of this
and other terminal emulation devices should set the device to 9600 baud, 8 data bits, 1 stop
bit, and no parity. Omnibook users should select "COMM 1", and use a 24542M or similar
9-pin to 25-pin serial cable for connection to port 0.
Memory Subsystem Configuration
The memory subsystem consists Single In-line Memory Modules (SIMMs) that plug into the
CPU card assembly.
Note
HP 9000/800 Ex5 Class memory SIMMs are not interchangeable (or
compatible) with any HP 9000/800 F, G, H, or I Class memory SIMMs.
Also, HP 3000/9X8LX/RX memory SIMMs are not interchangeable (or
compatible) with HP 3000/9X7LX/RX/SX memory SIMMs.
Figure 4-8 shows the memory SIMM card slot numbering scheme. Notice that there are four
slots, numbered 0 to 3 right to left, with two connectors per slot (A and B). These memory
slots are located on the CPU card near the card bulkhead.
