V\u00fdm\u011bna hlavn\u00edho jisti\u010de – 29.1.<\/h2>\n\n\n\n
Prvn\u00ed \u00fapravy prob\u011bhly v sobotu 29.1.<\/strong> Museli jsme vym\u011bnit zoufale nedostate\u010dn\u00fd 32 A hlavn\u00ed jisti\u010d od EONu za nov\u00fd jisti\u010d 80 A. To znamenalo odst\u00e1vku nap\u00e1jen\u00ed na 1 hodinu, na tu dobu jsme museli od elekt\u0159iny odpojit tak\u00e9 obyvatele sousedn\u00ed budovy. Na\u0161e servery byly nap\u00e1jeny z na\u0161eho gener\u00e1toru. V\u0161e prob\u011bhlo t\u00e9m\u011b\u0159 dle pl\u00e1nu, jen jeden server zaznamenal nepl\u00e1novan\u00fd v\u00fdpadek.<\/p>\n\n\n\n Dal\u0161\u00edm krokem, ke kter\u00e9mu dojde b\u011bhem p\u00e1r m\u011bs\u00edc\u016f, je v\u00fdm\u011bna hlavn\u00edho jisti\u010de na 200 A, to v\u0161ak znamen\u00e1 z\u00e1sadn\u011bj\u0161\u00ed p\u0159ed\u011bl\u00e1n\u00ed rozvad\u011b\u010d\u016f EONu a nata\u017een\u00ed nov\u00fdch p\u0159\u00edvodn\u00edch kabel\u016f do na\u0161\u00ed budovy. To u\u017e je s EONem v\u0161e domluven\u00e9 a p\u0159ipraven\u00e9, snad to brzy zrealizuj\u00ed.<\/p>\n\n\n\n V\u00fdrazn\u011b n\u00e1ro\u010dn\u011bj\u0161\u00ed operace prob\u011bhla v ned\u011bli 6.2. P\u0159epojila se cel\u00e1 p\u00e1te\u0159n\u00ed elektroinstalace. Musela b\u00fdt vym\u011bn\u011bna ve\u0161ker\u00e1 kabel\u00e1\u017e, zapojen byl nov\u00fd hlavn\u00ed rozvad\u011b\u010d. \u00dapravy se t\u00fdkaly tak\u00e9 na\u0161eho gener\u00e1toru, kter\u00fd tak nemohl b\u00fdt b\u011bhem t\u00e9to akce pou\u017eit. Proto jsme si pronajali je\u0161t\u011b dal\u0161\u00ed gener\u00e1tor, kter\u00fd po dobu 1. f\u00e1ze t\u00e9to akce z\u00e1soboval servery energi\u00ed.<\/p>\n\n\n\n V 1. f\u00e1zi<\/strong> jsme odpojili ATS (automatic transfer switch)<\/strong>. Jedn\u00e1 se o za\u0159\u00edzen\u00ed, kter\u00e9 podle situace p\u0159epojuje mezi p\u0159\u00edvodem energie z elektr\u00e1rny a z gener\u00e1toru. Z n\u011bj vede elekt\u0159ina do hlavn\u00edho rozvad\u011b\u010de a d\u00e1le do UPS a do server\u016f. ATS se p\u0159em\u00edstilo, p\u0159ivedla se k n\u011bmu nov\u00e1 kabel\u00e1\u017e od gener\u00e1toru, p\u0159ipojil se k n\u011bmu nov\u00fd hlavn\u00ed rozvad\u011b\u010d.

Nakonec jsme celou serverovnu p\u0159epojili na nov\u00fd rozvad\u011b\u010d, kter\u00fd byl nyn\u00ed nap\u00e1jen pouze z na\u0161eho gener\u00e1toru. T\u00edm mohl b\u00fdt zap\u016fj\u010den\u00fd gener\u00e1tor vypnut a odvezen pry\u010d.<\/p>\n\n\n\n Ve 2. f\u00e1zi<\/strong> bylo c\u00edlem vym\u011bnit p\u0159\u00edvodn\u00ed kabely od EONu. Nejprve jsme p\u0159epojili tak\u00e9 horn\u00ed patro budovy s kancel\u00e1\u0159emi na nov\u00fd rozvad\u011b\u010d. Pot\u00e9 byl shozen hlavn\u00ed jisti\u010d pro celou budovu a k ATS byl doveden nov\u00fd p\u0159\u00edvod od EONu.<\/p>\n\n\n\n V\u0161e prob\u011bhlo p\u0159esn\u011b dle pl\u00e1nu, i kdy\u017e to bylo \u010dasov\u011b n\u00e1ro\u010dn\u011bj\u0161\u00ed, ne\u017e jsme \u010dekali. Nejkomplikovan\u011bj\u0161\u00ed byla pr\u00e1ce s nov\u00fdmi kabely, kter\u00e9 bylo neuv\u011b\u0159iteln\u011b slo\u017eit\u00e9 oh\u00fdbat a zapojovat do t\u011bsn\u00e9 sk\u0159\u00edn\u011b s ATS. Nakonec cel\u00e1 operace trvala 7 hodin.<\/p>\n\n\n\n V\u00fdsledkem je, \u017ee v\u0161echny p\u00e1te\u0159n\u00ed elektrick\u00e9 rozvody v na\u0161\u00ed budov\u011b jsou nyn\u00ed dimenzov\u00e1ny na 200 A.
