Pakeng tsa para e 'ngoe le e' ngoe ea li-connector tsa I / O, li-connectors tse tharo tsa faston li fumaneha (ka lihlopha tse hlano) ho hokahanya matla ho li-module tsa I / O. Lihokelo tsa faston li tšoailoe ka tsela e latelang: • Tx-1 (e hokahane le d32 le z32 ea sehokelo sa I/O ka ho le letšehali le ka ho le letona) • Tx-2 (e hokahaneng le d30 le z30 ea li-connectors tsa I/O boemo ba rack 1 ho ea ho 10) • Tx-3 (e hokahaneng le d6 le z6 ea sehokelo se ka ho le letona le I/O). Lithakhisa tsa Tx-2 li sebelisetsoa 0 Vdc e tloaelehileng 'me kaofela li hokahane holim'a sefofane sa morao sa I/O. Pini e 'ngoe le e' ngoe ea faston e ka sebetsana le 10 A. Haeba mochine leha e le ofe oa rack o hloka matla a ka hare a 24 Vdc (ka pin d8 le z8), matla a ka hare a 24 Vdc a tlameha ho kopanngoa ka li-faston tse peli: • T11-3: 24 Vdc, le • T11-2: e tloaelehileng 0 Vdc. The watchdog (WDG), 5 Vdc le ground (GND) li hokahane le I/O backplane ka sehokelo CN11 (sheba Figure 3 le Figure 4). Ho arohana ha balebeli hoa khoneha ka ho tlosa li-jumpers WD1 ho WD3 le ho hokahanya lets'oao la 5 Vdc kapa lets'oao ho pini e tlase ea jumper. Jumper WD1 ke molebeli oa li-module tse maemong a rack 1 ho isa ho 3 (sehlopha sa ba bararo). Jumper WD2 ke molebeli oa li-module tse maemong a rack 4 ho isa ho 6 (sehlopha sa ba bararo). Jumper WD3 ke molebeli oa li-module tse maemong a rack 7 ho isa ho 10 (sehlopha sa ba bane). The I / O backplane e tla le likhokahano tse peli tsa lefatše tsa faston (T0 le T11-1). Maqhama ana a lefats'e a tlameha ho emisoa ho foreime ea rack ea I/O ho sebelisoa lithapo tse khutšoane (2.5 mm², AWG 14), mohlala, ka kotloloho boutung e haufi ea rack ea 19-inch I/O.
