Pakati pa gulu lililonse la I / O cholumikizira, zolumikizira zitatu za faston zilipo (m'magulu asanu) kuti zilumikize mphamvu ku ma module a I / O. Zolumikizira za faston zimalembedwa motere: • Tx-1 (yolumikizidwa ku d32 ndi z32 ya cholumikizira cha I/O kumanzere ndi kumanja) • Tx-2 (yolumikizidwa ku d30 ndi z30 ya zolumikizira za I/O poyikapo rack 1 mpaka 10) • Tx-3 (yolumikizidwa ku d6 ndi z6 cholumikizira kumanzere ndi I/O). Ma pini a Tx-2 amagwiritsidwa ntchito pa 0 Vdc wamba ndipo onse amalumikizana pa I/O backplane. Pini iliyonse ya faston imatha kugwira 10 A. Ngati gawo lililonse mu rack likufuna 24 Vdc mphamvu yamkati (pa pini d8 ndi z8), mphamvu yamkati ya 24 Vdc iyenera kulumikizidwa kudzera pazitsulo ziwiri: • T11-3: 24 Vdc, ndi • T11-2: wamba 0 Vdc. Woyang'anira (WDG), 5 Vdc ndi nthaka (GND) alumikizidwa ku I/O backplane kudzera cholumikizira CN11 (onani Chithunzi 3 ndi Chithunzi 4). Kupatukana kwa watchdog kumatheka pochotsa ma jumpers WD1 ku WD3 ndikulumikiza 5 Vdc kapena chizindikiro cha watchdog ku pini yapansi ya jumper. Jumper WD1 ndiye woyang'anira ma module omwe ali pamalo oyika 1 mpaka 3 (gulu la atatu). Jumper WD2 ndiye woyang'anira ma module omwe ali pa rack 4 mpaka 6 (gulu la atatu). Jumper WD3 ndiye woyang'anira ma module omwe ali pa rack 7 mpaka 10 (gulu la anayi). The I / O backplane imabwera ndi zolumikizira ziwiri zapadziko lapansi (T0 ndi T11-1). Malumikizidwe apadziko lapansi awa akuyenera kuthetsedwa ku chimango cha I/O pogwiritsa ntchito mawaya aafupi (2.5 mm², AWG 14), mwachitsanzo molunjika ku bawuti yapafupi ya 19-inch I/O rack.
