This maintenance object covers environmental maintenance for S8700-series servers <strong>and</strong><br />

S8500 servers equipped with multicarrier cabinets (MCCs), <strong>and</strong> for servers equipped with<br />

CMC1 or G600 carriers.<br />

<strong>test</strong> environment location Cabinet Sensors<br />

Note:<br />

Note: The CABINET MO for S8700-series servers <strong>and</strong> S8500 servers is valid only for<br />

multicarrier cabinets (MCCs). For information about environmental maintenance<br />

on single-carrier cabinets (SCCs), see DC-POWER (Single-Carrier Cabinet<br />

Environment).<br />

The cabinet sensors monitor cabinet temperature <strong>and</strong> fan rotation. Variable-speed fans are<br />

used extensively in S8700-series systems.<br />

The Maintenance circuit pack in an MCC PN monitors a temperature sensor (S1) at the top of<br />

the cabinet <strong>and</strong> generates a major alarm if the exit air temperature exceeds 65 degrees Celsius<br />

(149 degrees Fahrenheit). Another temperature sensor in the top of the cabinet (S2) also<br />

monitors exit air temperature. If it exceeds 70 degrees Celsius (158 degrees Fahrenheit), the<br />

power-distribution unit turns off all cabinet power <strong>and</strong> invokes emergency transfer. Other<br />

sensors monitor fan performance.<br />

The repair procedures that follow rely on your ability to distinguish between high <strong>and</strong> low fan<br />

speeds by the sound of the fans. Experience will allow you to distinguish between the high <strong>and</strong><br />

low pitches generated by high <strong>and</strong> low speeds. A thermometer is also required for some of the<br />

procedures that follow.<br />

In making replacements, observe the following rules:<br />

● New fan assemblies accept only variable-speed fans.<br />

● Old fan assemblies accept either variable- or constant-speed fans.<br />

● Replace a fan assembly (carrier) only with a fan assembly of the same type (new for new,<br />

old for old).<br />
