Procedure￿2￿Connector￿Check￿and￿Replacement￿Check￿

The￿LAN￿connector￿(RJ45)￿is￿mounted￿on￿the￿system￿board.￿￿If￿the￿LAN￿malfunctions,￿the￿ system￿board￿or￿CPU￿might￿be￿faulty.￿ Disassemble￿the￿computer￿following￿the￿steps￿described￿in￿Chapter￿4￿and￿perform￿the￿ following￿checks:￿

Check￿1￿ The￿system￿board￿may￿be￿faulty.￿￿Replace￿it￿with￿a￿new￿one￿following￿the￿ instructions￿in￿Chapter￿4.￿￿If￿the￿LAN￿is￿still￿not￿functioning￿properly,￿ perform￿Check￿2.￿

Check￿2￿ The￿memory￿may￿be￿defective.￿Replace￿the￿memory￿module￿with￿a￿new￿ one￿following￿the￿steps￿described￿in￿Chapter￿4.￿If￿the￿problem￿persists,￿ perform￿Check￿3.￿

Check￿3￿ The￿CPU￿may￿be￿faulty.￿Disassemble￿the￿computer￿following￿the￿steps￿ described￿in￿Chapter￿4￿and￿replace￿the￿CPU￿with￿a￿new￿one.￿
