imikhiqizo

Phakathi kwazo zonke izixhumi ze-I/O, izixhumi ezintathu ze-faston ziyatholakala (ngamaqembu amahlanu) ukuxhuma amandla kumamojula we-I/O. Izixhumi ze-faston zimakwe kanje: • I-Tx-1 (ixhunywe ku-d32 kanye no-z32 yesixhumi se-I/O kwesokunxele nakwesokudla) • I-Tx-2 (ixhunywe ku-d30 kanye no-z30 wezixhumi ze-I/O zokubeka indawo 1 kuya ku-10) • I-Tx-3 (ixhunywe ku-d6 kanye no-z6 kwesixhumi kwesokunxele kanye ne-O). Izikhonkwane ze-Tx-2 zisetshenziselwa i-0 Vdc evamile futhi wonke axhunywe endizeni engemuva ye-I/O. Iphinikhodi ngayinye ye-faston ingakwazi ukuphatha u-10 A. Uma noma iyiphi imojula kurack idinga amandla angaphakathi angu-24 Vdc (kuphinikhodi d8 ne-z8), amandla angaphakathi angu-24 Vdc kufanele axhunywe ngama-faston amabili: • T11-3: 24 Vdc, futhi • T11-2: evamile 0 Vdc. I-watchdog (WDG), 5 Vdc kanye ne-ground (GND) ixhunywe kundiza yangemuva ye-I/O ngesixhumi se-CN11 (bona Umfanekiso 3 kanye noMfanekiso 4). Ukuhlukaniswa kwe-Watchdog kungenzeka ngokukhipha ama-jumpers WD1 kuya ku-WD3 futhi uxhume isignali engu-5 Vdc noma i-watchdog kuphini elingezansi le-jumper. I-Jumper WD1 ingumlindi wamamojula asendaweni yokubeka 1 kuya ku-3 (iqembu labathathu). I-Jumper WD2 iwumlindi wamamojula asendaweni yokubeka 4 kuya ku-6 (iqembu labathathu). I-Jumper WD3 iyinkomba yamamojula asezindaweni zamarack 7 kuya ku-10 (iqembu labane). I-backplane ye-I/O iza nokuxhumana okubili kwe-faston yomhlaba (i-T0 ne-T11-1). Lokhu kuxhumana komhlaba kufanele kunqanyulwe kuhlaka lwe-I/O rack kusetshenziswa izintambo ezimfushane (2.5 mm², AWG 14), isb ngqo kwibhawodi eseduze ku-19-inch I/O rack.
