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 ser ver to the mpx100/100b
You can manage the mpx100/100b us ing the HP StorageWorks mpx Manag er 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 por t
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 con figure the ser ver
appropriately. This involves either setting the server IP address for Ethernet connections, or configuring
the server's serial port.
