Removing and Replacing line cards or RPMs

Step Task (continued)

5.Lift and hold the PEM interlock lever to release the PEM

6.While holding the interlock lever up, using the bottom handle, pull the PEM straight out of the slot.

Removing and Replacing RPMs, Line Cards, or SFMs

Warning:

• Do not remove a panel blank unless you are ready to install a line card, RPM, or SFM 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.

•Electrostatic discharge (ESD) damage can occur when components are mishandled. Always wear an ESD-preventive wrist or foot-heel ground strap when handling RPMs, SFMs, or line cards. (Connect the ESD strap to the grounding plug located on the front of the chassis.)

•After you remove the original packaging, place RPMs, SFMs, and line cards on an antistatic surface.

Note:

•If you operate your E1200i without redundant RPMs, the system enters a software-defined power-down state when you remove the only RPM for replacement.

•Your E1200i system will not function properly with fewer than eight SFMs.

You can add, replace, or remove modules without interrupting the system power or system operations. RPMs, line cards, and SFMs are hot-swappable. The E1200i system generates major alarm events for high temperatures (over 75°C) and module failures depending on the module and whether or not it is redundant. Minor alarms are generated for component temperatures over 65°C and 75°C for line cards. SNMP traps are sent for both alarm types. Refer to Appendix C, on page 87 for more details.
