Ma waena o kēlā me kēia hui hoʻohui I/O, loaʻa nā mea hoʻohui faston ʻekolu (i loko o ʻelima mau pūʻulu) e hoʻohui i ka mana i nā pālua I/O module. ʻO nā mea hoʻohui faston penei: • Tx-1 (pili me d32 a me z32 o ka mea hoʻohui I/O ma ka hema a me ka ʻākau) • Tx-2 (i hoʻopili ʻia me d30 a me z30 o nā mea hoʻohui I/O rack kūlana 1 a 10) • Tx-3 (pili me d6 a me z6 o ka mea hoʻohui I/O hema a ʻākau). Hoʻohana ʻia nā pine Tx-2 no ka 0 Vdc maʻamau a ua hui pū ʻia ma ka mokulele I/O. Hiki i kēlā me kēia pine faston ke mālama i ka 10 A. Inā makemake kekahi module i loko o ka pahu i ka mana kūloko 24 Vdc (ma ka pine d8 a me z8), pono e hoʻopili ʻia ka mana kūloko o 24 Vdc ma o ʻelua fastons: • T11-3: 24 Vdc, a • T11-2: maʻamau 0 Vdc. Hoʻopili ʻia ka ʻīlio kiaʻi (WDG), 5 Vdc a me ka lepo (GND) i ka I/O backplane ma o ka mea hoʻohui CN11 (e nānā i ke Kiʻi 3 a me ke Kiʻi 4). Hiki ke hoʻokaʻawale ʻia ka ʻīlio kiaʻi ma ka wehe ʻana i nā mea lele WD1 i WD3 a hoʻohui i kahi hōʻailona 5 Vdc a i ʻole kiaʻi kiaʻi i ka pine haʻahaʻa o ka lele. ʻO Jumper WD1 ka ʻīlio kiaʻi no nā modula ma nā kūlana rack 1 a 3 (hui ʻekolu). ʻO Jumper WD2 ka ʻīlio kiaʻi no nā modula ma nā kūlana rack 4 a 6 (hui ʻekolu). ʻO Jumper WD3 ka ʻīlio kiaʻi no nā modula ma nā kūlana rack 7 a 10 (hui ʻehā). Hele mai ka I/O backplane me ʻelua mau pilina honua (T0 a me T11-1). Pono e hoʻopau ʻia kēia mau hoʻokuʻi honua i ka pā I/O me ka hoʻohana ʻana i nā uwea pōkole (2.5 mm², AWG 14), no ka laʻana i ka pahu kokoke loa ma ka pā I/O 19-inihi.
