HPE G2 R5000 3U

Connecting the serial communications port
CAUTION: Use only the computer interface cable supplied with the UPS to connect the communications port to the host
computer.
NOTE: This port is only used for firmware upgrades. To update the UPS firmware, see the Hewlett Packard Enterprise
website.
Connecting the RPO port
WARNING: To meet the requirements stated in NEC (NFPA 70) Articles 645-10 and 645-11, a UPS installed in a
computer equipment room must be connected to an RPO circuit.
IMPORTANT: The remote switch must be in the O (open) position to enable power to the output receptacles.
NOTE: Wire the connector block using stranded, nonshielded wire (AWG #22 - #18, or equivalent).
Separate wire pairs are attached to a single, normally open contact in a parallel connection. Hewlett Packard Enterprise
recommends using dierent colors for the positive and negative wires.
If a connector becomes disconnected and is reconnected with reversed polarity, an RPO is initiated. To avoid RPO port
disconnect:
• Minimize wire strain while connecting the RPO port.
• Avoid allowing the wires to hang in the rear of the UPS.
• Use tie wraps and tie wrap blocks to secure the wires tightly to the rack and the rear of the UPS.
