CAUTION: Unlock the levers before inserting an RPM or line card into the chassis. After you insertthe RPM or line card, fully engage the locking mechanism; without the locking mechanismengaged, you can damage a lower line card when you insert it.Installing an RPMInstall the fan modules before you install RPMs in a C9010 switch.Figure 20.

PSU Status LED9. 10GbE SFP+ ports with Link LEDsBefore you install an RPM in the C9010 chassis, review these guidelines:• Although the C9010 switch can operate with one RPM, Dell Networking recommends two RPMs forredundancy and to provide more bandwidth to each line card. One RPM provides 120 Gigabits ofbandwidth to each line card; two RPMs provide 240 Gigabits of bandwidth to each line card.• If the C9010 operates with only one RPM, you can install the RPM in either slot 10 (the top RPM slotlabelled R0) or slot 11 (the bottom RPM slot labelled R1) . If you install two RPMs, the RPM in slot 10 ismaster and the RPM in slot 11 is standby by default. See Figure 1 for RPM slot locations.• To control airflow for adequate system cooling and ensure personal safety and electromagneticinterference (EMI) containment during operation, install a blank in an empty RPM slot. Always replacean RPM or a blank panel immediately.• The blank panels for RPMs and line cards are different sizes (RPM blanks are full-width); be sure toinstall the correct blank panel in each empty slot.• RPMs are hot-swappable. The C9010 supports high availability.• If your system uses two RPMs, both RPMs must have the same software image.Installing the Hardware 29
