iimveliso

Phakathi kwazo zonke izibini ze-I / O zokudibanisa, izixhumi ezintathu ze-faston ziyafumaneka (ngamaqela amahlanu) ukudibanisa amandla kwii-module ze-I / O. Izihlanganisi ze-faston ziphawulwe ngolu hlobo lulandelayo: • Tx-1 (iqhagamshelwe kwi-d32 kunye ne-z32 yesiqhagamshelanisi se-I/O ekhohlo nasekunene) • Tx-2 (iqhagamshelwe kwi-d30 kunye ne-z30 ye-I/O yezihlanganisi indawo yokubeka i-1 ukuya kwi-10) • Tx-3 (iqhagamshelwe kwi-d6 kunye ne-z6 yesiqhagamshelanisi sasekhohlo kunye ne-O). Izikhonkwane ze-Tx-2 zisetyenziselwa i-0 Vdc eqhelekileyo kwaye zonke zidibene kwi-backplane ye-I / O. I-pini nganye ye-faston inokusingatha i-10 A. Ukuba nayiphi na imodyuli kwi-rack idinga i-24 Vdc amandla angaphakathi (kwi-pin d8 kunye ne-z8), amandla angaphakathi e-24 Vdc kufuneka adibaniswe ngeefasons ezimbini: • T11-3: 24 Vdc, kunye • T11-2: eqhelekileyo 0 Vdc. I-watchdog (WDG), i-5 Vdc kunye nomhlaba (GND) ixhunyiwe kwi-backplane ye-I / O nge-connector CN11 (jonga i-Figure 3 kunye ne-Figure 4). Ukuhlukana kwe-Watchdog kunokwenzeka ngokususa i-jumpers WD1 kwi-WD3 kunye nokudibanisa i-5 Vdc okanye i-watchdog signal kwi-pin ephantsi ye-jumper. I-Jumper WD1 yi-watchdog yeemodyuli kwiindawo zokubeka i-1 ukuya kwi-3 (iqela labathathu). I-Jumper WD2 yi-watchdog yeemodyuli kwiindawo ze-rack 4 ukuya kwi-6 (iqela labathathu). I-Jumper WD3 yi-watchdog yeemodyuli kwiindawo ze-rack 7 ukuya kwi-10 (iqela lezine). I-backplane ye-I / O iza kunye noqhagamshelwano lwe-faston ezimbini zomhlaba (T0 kunye ne-T11-1). Olu nxulumano lomhlaba kufuneka lupheliswe kwi-rack ye-I/O kusetyenziswa iingcingo ezimfutshane (2.5 mm², AWG 14), umz. ngokuthe ngqo kwibholithi ekufutshane kwi-19-intshi ye-I/O yerekhi.
