Installation and maintenance
This section describes how to install and configure the mpx100/100b. It also describes how to update
new firmware and recover a disabled mpx100/100b.
For the mpx100/100b hardware installation, see
“ Installing and upgrading EVA iSCSI connectivity ” on page 39.
Power requirements
Power requirements for the mpx100/100b are 0.5 Amp at 100 VAC or 0.25 A at 240 VAC.
Environmental conditions
Consider the factors that affect the climate in your facility, such as equipment heat dissipation and
ventilation. The mpx100/100b requires the following operating conditions:
• Operating temperature range: 5°–40° C (41°–104° F)
• Relative humidity: 15–80%, noncondensing
Connecting the server to the mpx100/100b
You can manage the mpx100/100b using the HP StorageWorks mpx Manager or the CLI. HP
StorageWorks mpx Manager requires an Ethernet connection to the mpx100/100b management port.
The CLI uses either an Ethernet connection or a serial connection. Choose the mpx100/100b management
method, then connect the management server to the mpx100/100b in one of the following ways:
• Indirect Ethernet connection from the management server to the mpx100/100b RJ-45 connector
through an Ethernet switch or hub.
• Direct Ethernet connection from the management server to the mpx100/100b RJ-45 Ethernet
connector.
• Serial port connection from management workstation to the mpx100/100b RS-232 serial port
connector. This requires a 10/100 Base-T straight cable and a dongle.
Configuring the server
If you plan to use the CLI to configure and manage the mpx100/100b, you must configure the server
appropriately. This involves either setting the server IP address for Ethernet connections, or configuring
the server's serial port.
