Dell Force10 E300 Installing and Maintaining the E300 System - Page 47

To remove an AC Power Supply: Step Task 1 Toggle the switch on the AC Power Supply to the OFF position. 2 Disconnect the power cable from the AC power source. 3 Loosen the retaining screws. 4 Pull the AC Power Supply out of the slot. 5 If you are replacing an AC Power Supply, go to Chapter 5, Installing Power Modules, on page 19. If you are replacing an AC Power Supply, go to Chapter 5, Installing Power Modules. If you are not replacing the AC Power Supply, insert a power module blank filler in the empty slot. Removing and Replacing RPMs, Line Cards, or SFMs WARNING: Your E300 system will not send traffic at line rate with only one SFM. WARNING: Electrostatic discharge (ESD) damage can occur when components are mishandled. Always wear an ESD-preventive wrist or ankle strap when handling RPMs, SFMs, or line cards. Connect the ESD strap to the grounding plug located on the front of the chassis. Place RPMs, SFMs, and line cards on an antistatic surface and anti-static bags when they are not installed. WARNING: Do not remove a panel blank unless you are ready to install a line card or RPM into that slot. If you remove a card, immediately replace the empty slot with a panel blank. Blanks are required to control airflow and electromagnetic interference. NOTE: If you operate your E300 without a redundant RPMs, the system enters a software-defined powerdown state when you remove the only RPM for replacement. You can add, replace, or remove E300 modules without interrupting the system power or system operations. RPMs and line cards are hot-swappable. The E300 System system generates major alarm events for high temperatures (over 75°C for RPMs and SFMs; over 80°C for line cards) and module failures depending on the module and whether or not it is redundant. Minor alarms are generated for component temperatures over 65°C for RPMs and SFMs; over 75°C for line cards. SNMP traps are sent for both alarm types. Refer to Appendix C, Alarms, on page 57 for more details. You can add, replace, or remove E300 modules without interrupting the system power or system operations.

If you are not operating your system with redundant cards (with only one SFM or one RPM) you must power off your system until the cards are replaced. Removing and Replacing Components | 47
