Installing and Maintaining the E1200i System 71
Removing and Replacing RPMs, Line Cards, or 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.
Removing and Replacing line cards or RPMs
To remove and replace E1200i line card or RPM modules:
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.
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.
Step Task
1. Unplug the network interface cables connected to the line card or RPM.
2. Loosen the captive screws and pull the ejector levers simultaneously toward you to disengage the
backplane connections.
3. Slide the card out of the slot and store the cards in the original antistatic packaging.
4. If you are immediately installing a replacement card, align the new card with the guide, and gently slide
the card into the slot until you feel the connectors engage with the chassis backplane.
If you are not planning to install a new card immediately, install a blank panel.
