The Power 780 operator interface/controls located on the front panel of the primary I/O
drawer consist of a power ON/OFF button with a POWER indicator, an LCD display for
diagnostic feedback, a RESET button, and a disturbance or system attention LED.
Additional considerations: Note the following considerations:
򐂰 The Ethernet ports of the Integrated Multifunction Card cannot be used for an IBM i
console. Separate Ethernet adapters that can be directly controlled by IBM i without
the Virtual I/O server should be used for IBM i LAN consoles if desired. Alternatively,
an HMC can also be used for an IBM i console.
򐂰 The first and second CEC enclosure must contain one Integrated Multifunction Card
(#1768 or #1769). The Integrated Multifunction Card is optional for the third or fourth
CEC enclosure.
򐂰 Each Integrated Multifunction Card has four Ethernet ports, two USB ports, and one
serial port. Usage of the serial port by AIX/Linux is supported for MODEM call home,
TTY console, and snooping even if an HMC/SDMC is attached to the server. Usage
by the serial port to communicate with a UPS is not supported.
򐂰 The first and second CEC enclosures each have two HMC/SDMC ports on the
service processor (#EU05). If there are two CEC enclosures, the HMC must be
connected to both service processor cards.
