1. FEPS control and monitoring. Superdome has six BPS and the UGUY sends 5V to the BPS for use by the fault collection circuitry. 2. Fan control and monitoring. In addition to the blowers, there are five I/O system fans above and between the I/O bays. These fans run at full speed all the time. There is no fan speed signal. 3. Cabinet mode and cabinet number fan out. The surface mount dip switch on the HUCB (UGUY backplane) is used to configure a Superdome cabinet for normal use or as an SD16 cabinet. Use the 16-position thumb switch on the UGUY to set the cabinet number. Numbers 0-7 are for CPU-oriented cabinets and numbers 8-15 are for I/O-only cabinets. 4. Local Power Monitor (LPM) interfaces. Each big board (cell board, I/ O backplane, and main backplane) contains logic that controls conversion of 48 V to lower voltages. The PM3 interfaces to the LPM with the board-present input signal to the PM3 and the power-enable output signal from the PM3. 5. Front and rear panel board control. System Clocks The sx2000 system clock differs from the sx1000 system clock in that the system clocks are only supplied from the backplane and to the backplane crossbar ASICs and the cell boards. There is no distribution of the system clocks to the I/O backplanes. Instead, independent local clock distribution is provided on the I/O backplane. The system clocks are not provided by the PM3 on sx2000 servers. The sx2000 system clock source resides on the system backplane. Management Processor The MP is comprised of two PCBs, the SBC and the SBCH.The MP is a hot-swappable unit powered by +5 V HKP that holds the MP configuration parameters in compact flash and the error and activity logs and the complex identification information or complex profile in battery backed NVRAM. It also provides the USB network controller (MP bus). Each complex has one MP per complex. It cannot be set up for redundancy. However, it is not a single point of failure for the complex because it can be hot-swapped. If the MP fails, the complex can still boot and function. However, the following utility functions are lost until the MP can be replaced: • Processing and storing log entries (chassis codes) • Console functions to every partition • OL* functions • VFP and system alert notification • Connection to the MP for maintenance, either locally or remotely • Diagnostics (ODE and scan) 24 Overview
