Core I/O Connections

Each hp Integrity rx5670 contains one core I/O board set, consisting of an MP/SCSI board and a LAN/SCSI board. The MP/SCSI board is located in PCI slot 1. The LAN/SCSI board is located in PCI slot 3.

MP/SCSI Connections

The MP/SCSI board is required to access the console, access all but two of the internal peripherals, and utilize other features of the system.

Connections to the MP/SCSI board include the following:

DB25 connector via the M cable (part number A6144-63001)
This RS232 connector provides connections for a local console, external modem, and a UPS. The server end of the M cable terminates in a DB25 connector. The opposite side of the cable terminates in 3 DB9 connectors labeled CONSOLE, REMOTE, and UPS.
10/100 Base-T LAN RJ45 connector (for LAN access to the management processor)
This LAN connection is available whenever the system is connected to a power source, even if the server main power switch is in the off position.
Internal Ultra SCSI (wide) channel for two internal mass storage devices
Internal Ultra SCSI (narrow) channel for connection to internal removable media device

LAN/SCSI Connections

The LAN/SCSI board provides the basic external I/O connectivity for the system.

Connections to the LAN/SCSI board include the following:

Internal Ultra SCSI (wide) channel for two internal mass storage devices
External LVD Ultra 160 SCSI channel connected to a 68-pin VHDCI connector
10/100/1000 Base-T LAN RJ45 connector (for LAN access to the system)

Management Processor

The management processor is an independent support system for the server. It provides a way for you to connect to a server and perform administrative or monitoring tasks for the server hardware.

The management processor controls power, reset, and transfer of control (TOC) capabilities, provides console access, displays and records system events, and can display detailed information about the various internal subsystems. The management processor also provides a virtual front panel which can be used to monitor the system status and see the state of front panel LEDs. All MP functions are available via the MP LAN, local RS-232 and remote RS-232 ports.

The management processor is available whenever the system is connected to a power source, even if the server main power switch is in the off position.

Access to the management processor can be restricted by user accounts. User accounts are password protected and provide a specific level of access to the server and management processor commands.

Multiple users can interact with the management processor. From the MP MAIN MENU users can select any of the following options: enter management processor command mode, enter console, view event logs, view console history, display virtual front panel, enter console session, or connect to another management processor. Multiple users can select different options from the MP MAIN MENU at the same time. However, management processor command mode and console mode are mirrored. The MP allows only one user at a time to have write access to the shared console.

Accessing the Management Processor

You can connect to the management processor using the following methods:

The local RS-232C port using a local terminal
The remote RS-232C port using external modem (dial-up) access, if remote modem access is configured
The management processor LAN port using web console or telnet if login access through the management processor LAN is enabled




	NOTE: The M cable (part number A6144-63001) must be connected to the DB25 connector located on the MP/SCSI board to allow a local terminal connection. The MP/SCSI board is located in PCI Slot 1. If a local terminal is not available, the management processor may be configured using a network connection. Details for configuring the management processor via a network are found in the section titled “Network Access to the Management Processor.”

Local Terminal Access to the Management Processor

Communication with the management processor is established by connecting a terminal to the Local RS-232 port on the MP/SCSI Core I/O board.

A terminal session may be established using a standalone terminal, or using terminal emulation software such as Reflection 1 running on a PC.

During installation, communicating with the management processor enables such tasks as:

Verifying that the components are present and installed correctly
Setting the LAN IP addresses

Setting Terminal Parameters

After powering on the terminal, ensure the communications settings are as follows:

8/none (parity)
9600 baud
None (Receive)
None (Transmit)

If the terminal is a PC using Reflection 1, check or change these communications settings using the following procedure:

From the Reflection 1 Main screen, pull down the Connection menu and select Connection Setup.
Select Serial Port.
Select Com1.
Check the settings and change, if required.
Go to More Settings to set Xon/Xoff. Click OK to close the More Settings window.
Click OK to close the Connection Setup window.
Pull down the Setup menu and select Terminal (under the Emulation tab).
Select a supported terminal type.
The preferred type is VT100+.
Click Apply.
This option is not highlighted if the terminal type you want is already selected.
Click OK.

Accessing the Management Processor Using a Modem

Use the SA command to enable/disable the prt and give the modem control over to the MP or the OS.

Log into the MP and configure the modem using the CA command. Ensure the communications settings are as follows:
- TERMINAL TYPE—Vt100 vs. HPterm
- BAUD RATES—Input and output data rates are the same; 300, 1200, 2400, 4800, 9600, 38400, 115200 bit/sec
- FLOW CONTROL—Hardware uses RTS/CTS; software uses Xon/Xoff
- TRANSMIT CONFIGURATION STRINGS—Disable this setting whenever the modem being used is not compatible with the supported modem.
- MODEM PRESENCE—When the modem may not always be connected, set this parameter to “not always connected”. For example: a modem attached through a switch. In this mode, no dial out functions are allowed and paging in not possible.
- MODEM PROTOCOL—Bell or CCITT (CCITT is a European standard; RTS/CTS signaling is used, as well as the Ring signal. Bell is a U.S. or simple mode.)
Enable modem access to the MP using the SA command. Set Remote Port access to Management Access.
Configure the modem and dial-up software on your remote computer to match the setting on the rx5670 and LAN/SCSI card.
Dial in using the procedures required by your dial-up software.
Wait for the MP login to display on the screen.

Network Access to the Management Processor

By connecting the management processor LAN port to an active network, another host on the same subnet can set the management processor IP address via the ping command. After the IP address has been set, a telnet session can be established to configure additional parameters.

To configure the management processor LAN IP address, perform the following steps:

Determine the MAC address of the management processor LAN interface by viewing the label located at the rear of the server.




	NOTE: If this label is missing, another label can be found at the front of the MP/SCSI card. You might need to remove the MP/SCSI board to view this label. For instructions on removing/replacing the MP/SCSI board, review chapter 6. The section is titled “Removing and Replacing PCI cards”.

Connect a LAN cable on your local subnet to the LAN port found on the MP/SCSI board.

Add an ARP table entry to another host located on your local subnet. This ARP table entry will map the MAC address of the MP/SCSI LAN interface to the IP address chosen for that interface.




	NOTE: Adding an entry to the ARP table is typically done using the ARP command with the appropriate option. For example, arp -s is used with Windows. Consult your operating system documentation for more information.

Use the ping command from the host that has the new ARP table entry. The destination address is the IP address that is mapped to the MAC address of the management processor. The management processor LAN port should now be configured with the appropriate IP address.
Use the telnet command to connect to the management processor from a host on the local subnet.

Interacting with the Management Processor

To interact with the management processor, perform the following steps:




	NOTE: On initial system installation, the MP has two default user accounts. They are: 1. Administrator level user; login = Admin, password = Admin (both are case sensitive) 2. Operator level user; login = Oper, password = Oper (both are case sensitive). For security reasons, it is recommended that the UC command be used during the initial logon session (enter `CM` at the `MP` prompt, and enter `UC` at the `MP:CM>` prompt) to modify default passwords or to delete and create user accounts.




	NOTE: The management processor will start with the MP MAIN MENU displayed. In the following steps it is assumed that this was the starting condition. If you are not at the MP MAIN MENU, use CTRL-B to return to the MP MAIN MENU.

Use the management processor menus and commands as needed. Main menu commands are shown in Figure 3-2 “The MP MAIN MENU”. Commands not displayed in the MP MAIN MENU can be accessed in command mode by first using the CM command at the MP prompt. A list of available commands is presented in Table 3-1 “Management Processor Commands and Descriptions” and can be displayed by using the management processor help function (enter HE followed by LI at the MP> prompt). You can return to the MP MAIN MENU by typing Ctrl-B.
Figure 3-2 The MP MAIN MENU
Log out using the X command (enter X at the MP> prompt) after returning to the MP MAIN MENU.

Configuring Management Processor LAN Information

LAN information includes the management processor network name, the management processor IP address, the management processor subnet mask, the management processor gateway address, and the web console port number.

To set the management processor LAN IP address:

At the MP MAIN MENU prompt (MP>), enter CM to select command mode.
At the command mode prompt (MP:CM>), enter LC (for LAN configuration).
The screen displays the default values and asks if you want to modify them. It is good practice to write down the information, as it may be required for future troubleshooting.
