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 power-
down 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
for more details.

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.
