0. TPU XIO Board Introduction This document accompanies the SGI Tensor Processing Unit (TPU) XIO board and contains information about the TPU power requirements, panel plate and LEDs, software installation, and slot selection requirements for these Silicon Graphics chassis: • SGI Origin 2000 servers • SGI 2200, SGI 2400, and SGI 2800 servers • Silicon Graphics Onyx2 deskside systems • SGI Origin 200 Gigachannel servers The TPU is a high-performance, advanced digital signal processor.
TPU XIO Board Introduction Part Verification Open the XT-TPU-ORIGIN-1 box and verify that these components are included: • One SGI TPU XIO board in antistatic bag, part number 013-2590-xxx • One SGI Tensor Processing Unit (TPU) XIO Board Introduction, part number 007-4222-xxx (this document) Maximum Number of TPU Boards Table 1 summarizes the maximum number of TPU XIO boards that can be installed into the different chassis and systems.
Panel Plate and LEDs Unlike most XIO boards, the TPU XIO panel plate has no ports. It contains three round LEDs. During normal operation, these LEDs illuminate green. • 2.5 PWR: indicates that 2.5 voltage is supplied to the board. • 3.3 PWR: indicates that 3.3 voltage is supplied to the board. • LINK UP LED: indicates that communications have been established with the system. If a problem occurs with power or communications to the board, the LEDs illuminate amber. 3.3 LINK 2.5 PWR PWR UP LEDs 2.
TPU XIO Board Introduction Software Installation and Configuration If your system is currently up and running, save yourself time and extra system reboots by installing and configuring the correct version of IRIX before the board is installed. Follow the instructions below: 1. Verify that IRIX 6.5.5 or greater is installed: % versions eoe I eoe I eoe.sw.base date IRIX Execution Environment, version...
Slot Selection Follow the instructions in this section to select an appropriate XIO slot.

Slot Selection Rules for Onyx2 Deskside Systems Each Onyx2 node board accommodates a maximum of 3 TPU cards. The Onyx2 deskside system has 6 XIO slots. Slots 3, 5, and 6 (shown in Figure 3) are available for TPU XIO boards. It is recommended that you fill available odd-numbered slots before filling even-numbered ones, and that you fill lower-numbered slots before higher-numbered ones. For example, fill slot 3 before filling either slot 5 or slot 6.

Slot Selection Rules for Origin 200 Gigachannel Servers The Origin 200 Gigachannel expansion cabinet has 5 XIO slots, which are numbered 11–15. A maximum of 3 of the 5 XIO slots are available for TPU cards; no restrictions exist on which 3 of the 5 slots you select.

TPU XIO Board Introduction The server installation instructions provide information that can help you determine which of the slots are activated. Note: In general, if a module has a Node board in slot N1 or N3, then XIO slots 1-6 are available. If it has a Node board in slot N2 or N4, XIO slots 7-12 are available. If a module has at least two Node boards (one in N1 or N3 and one in N2 or N4), then all 12 XIO slots are available. 4. Select a slot for the TPU XIO board.

TPU XIO Board Introduction Startup When the board is installed and connected, follow the instructions in this section to start operation. 1. Power on the system. Follow the appropriate power-on instructions for the system's configuration. 2. Log on. 3. Verify that the three LEDs on the board illuminate green. If any LED fails to illuminate, ensure that the correct software is installed and configured; refer to “Software Installation and Configuration” on page 4.
