CHAPTER 6 System Configuration
l Life-span of UPS is shortend by operating in high-temperatures. Be sure to keep the
temperature of the installation environment 30 C (86 F) or lower, even when the main unit
is not in operation.
l Leaving UPS unconducted for a long time with the main unit off may prevent recharging to
the UPS. The UPS becomes unusable. To avoid such loss when leaving the main unit non-
operational for a long time, be sure to recharge the UPS for about 24 hours every six months.
l When frequent power failures have occurred, the UPS life span may be shortened due to
frequent recharging.
l Verify the UPS battery is always charged and that the battery recharges after a power outage.
l If the UPS is not recharged and it is left unused after a power failure has occurred, the
electrodes of the battery may corrode. To avoid this, recharge the UPS within 7 days after
the power failure occurred.
l The UPS activates when power failure occurs and while the main unit is operating. If the
power supply to the distribution panel is shut down while the main unit is operating, the
shutdown is recognized as power failure. The UPS then activates and the battery discharges.
To avoid this, be sure to shut down the main unit before shutting down the distribution panel.
l When selecting a UPS that is connected to the main unit, consider the total power
consumption, including the power consumption of the main unit, the file units, and the HUB.
l To connect the main unit's UPS and the UPC connector, prepare a UPS cable and a branch
adapter for UPS cable connection. UPC connectors are provided; two ports in each unit.
Use the connectors to connect the respective UPSs for the power systems.
For details on UPC connector, see
6.1.5

On-board LAN Port

l Each System Board has one on-board LAN port. A unique MAC address is assigned to a
specific partition. Therefore, all System Boad LAN port assigned to the same partition have
the same MAC address.
l To operate the main unit with the SMC, one of the System Board LAN ports that construct
the partition must be connected to the same User LAN SMC connected segment.
l If connection with multiple LAN segments is required for adding PCI cards or for other
reasons, select one of the following methods according to the value of "local-mac-address?"
of the OBP environmental variables. The default value of "local-mac-address?" is "false".
For details on OBP environment variables, see
- When "local-mac-address?" is "false"
To connect multiple LAN segments in a partition, each system board in a partition must
be connected to a separate LAN segment.
- When "local-mac-address?" is "true"
When a PC card is added, connection to multiple ports within the same LAN segment is
possible. On the other hand, on-board LAN ports in a partition cannot be connected to
other ports in the same segment, even if "local-mac-address?" is set to "true".
For details, contact a certified service engineer.
l For information about the operation of the enhancement PCI cards, follow the instructions in
the document supplied with the PCI cards.
