• DB25 connector, by way of the M cable
This RS-232 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 three DB9 connectors labeled CONSOLE, UPS, and REMOTE.
• 10/100 Base-T LAN RJ45 connector (for LAN and web console access).
This LAN uses standby power and is still active if the front panel power switch is off and
AC is present.
• Internal LVD Ultra 160 SCSI channel for connections to internal mass storage
• Internal SE Ultra SCSI channel for connection to an internal removable media device.

LAN/SCSI Connections

The LAN/SCSI board is a PCI form factor card that provides the basic external I/O connectivity
for the system.
Connections to the LAN/SCSI board include the following:
• PCI-X to PCI-X bridge for multi-device compatibility.
• Internal LVD Ultra 160 SCSI channel for connections to internal mass storage.
• External LVD Ultra 160 SCSI channel connected to a 68-pin VHDCI connector.
• 10/100/1000 Base-T LAN RJ45 connector.
The primary LAN interface is located on the LAN/SCSI board installed in the right-most slot
when viewing the system from the back.

Management Processor Access

NOTE: To access the MP for the initial installation, you must first connect the M cable to the
DB25 connector located on the primary MP/SCSI board. The primary MP/SCSI board is located
in the lower MP/SCSI board slot.

Setting Up the Customer Engineer Tool (PC)

The Customer Engineer (CE) Tool is usually a laptop. It enables communication with the MP in
the HP 9000 rp7420 server. The MP monitors the activity of either a one partition or a
multiple-partition configuration.
During installation, communicating with the MP enables such tasks as:
• Verifying that the components are present and installed correctly
• Setting LAN IP addresses
• Shutting off cell board power
Communication with the MP is established by connecting the CE Tool to the local RS-232 port
on the MP Core I/O card.

Setting CE Tool Parameters

After powering on the CE Tool, ensure the communications settings are as follows:
• 8/none (parity)
• 9600 baud
• na (Receive)
• na (Transmit)
If the CE Tool is a laptop using Reflection, ensure communications settings are in place by
following these steps:
1. From the Reflection Main screen, pull down the Connection menu and select Connection
Setup.
