Gaining Access to Memory Modules

Before you can replace the DRAM SIMM, you must gain access to it by removing the safety cover and the network expansion module, if one is installed. To gain access to the DIMM, you only need to remove the safety cover.

Electrical Hazard: To prevent exposure to an energy hazard in a 7H4385-49 connected to an external N-POE Power System, disconnect the 48-Vdc power cable from the 48-Vdc input connector before servicing or removing the 7H4385-49.

Riesgo Eléctrico: Para prevenir la exposicion a un riesgo electrico en una tarjeta 7H4385-49 conectada a un sistema externo de energia N-POE Power System, desconectar el cable de poder de 48-Vdc del conector de entrada 48-Vdc antes de dar servicio o remover la tarjeta 7H4385-49.

Elektrischer Gefahrenhinweis: Um den Schutz vor el. Schäden des Moduls

(7H4385-49) zu gewähleisten, bei Verwendung der N-POE Systeme, sollte dies bevor man dieses entnimmt oder Servicearbeiten daran vornimmt, vom 48-Vdc Stecker getrennt werden.
