70 IBM Power 770 and 780 Technical Overview and Introduction
Table 2-18 lists the slot configuration of the Power 770 and Power 780.

2.7.1 Blind-swap cassettes
The Power 770 and Power 780 uses new fourth-generation blind-swap cassettes to manage
the installation and removal of adapters. This new mechanism requires an interposer card
that allows the PCIe adapters to plug in vertically to the system, allows more airflow through
the cassette, and provides more room under the PCIe cards to accommodate the GX+
multifunctional host bridge chip heat sink height. Cassettes can be installed and removed
without removing the CEC enclosure from the rack.
2.7.2 System ports
Each CEC enclosure is equipped with a Integrated Multifunction Card (#1768 or #1769). This
integrated card provides two USB ports, one serial port, and four Ethernet connectors for a
processor enclosure and does not require a PCIe slot. When ordering a Power 770 or
Power 780, the following options can be selected:
򐂰 Dual 10 Gb Copper and Dual 1 Gb Ethernet (#1768)
򐂰 Dual 10 Gb Optical and Dual 1 Gb Ethernet (#1769)
All of the connectors are on the rear bulkhead of the CEC, and one Integrated Multifunction
Card can be placed in an individual CEC enclosure. An Integrated Multifunction Card is
required in CEC enclosures one and two, but it is not required in CEC enclosures three or
four. On a multi-enclosure system, the Integrated Multifunction Card features can differ. The
copper twinax ports support up to 5 m cabling distances. The RJ-45 ports support up to
100 m cabling distance using a Cat5e cable. The optical ports only support the 850 Nm optic
cable (multi mode cable) and support up to 300 m cabling distances.
The Power 770 and Power 780 each support one serial port in the rear of the system. This
connector is a standard 9-pin male D-shell, and it supports the RS232 interface. Because the
Power 770 and Power 780 are managed by an HMC/SDMC, this serial port is always
controlled by the operating system, and therefore is available in any system configuration. It
is driven by the integrated PLX Serial chip, and it will support any serial device that has an
operating system device driver. The FSP virtual console will be on the HMC /SDMC.
