Always wear an ESD-preventive wrist or foot-heel ground strap when handling RPMs, SFMs, or line cards. Place RPMs, SFMs, and line cards on an antistatic surface when they are not installed.

Installing RPMs, Line Cards, and SFMs
The E300 System accommodates six line cards, two Route Processor Module (RPMs), and two Switch
Fabric Modules (SFMs).
RPMs
The E300 system requires the installation of at least one RPM, although two are recommended for
redundancy. RPMs are designed to be installed in either the R0 or R1 slot. Do not force RPMs into line
card slots. RPMs are keyed differently than line cards to prevent improper installation.
You can hot-insert a second RPM into a running system without performance interruption or software
intervention. A second RPM for redundant functionality provides uninterrupted operability if the system
transitions from the active RPM to the standby RPM. The standby RPM constantly performs updates and
receives the same configuration information received by the active RPM. The standby RPM also
performs diagnostics on its subsystems. In the event of a switch over, the standby RPM immediately
takes over and resumes the control activities that the active RPM was performing.

The RPM Major and Minor Alarm LEDs are controlled by software that sets the threshold levels for
triggering the different alarm stages.
Blank Panels
CAUTION:
To ensure clean air and emission integrity (EMI), install blank panels for RPMs and line cards slots
not in use. Always replace cards or blank panel immediately.
Blank panels for RPMs and line cards must be installed in empty slots to control airflow. Blank panels are
shipped with the system to ensure that all chassis slots are installed with operational modules or blanks.
The blank panels do not have board components or connector pins. Align the blank with the guides and
gently slide toward the backplane.
Unpacking Cards
WARNING:
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. Place
RPMs, SFMs, and line cards on an antistatic surface when they are not installed.
