CAUTION: Any slot not filled with a line card or RPM must be filled with a blank to ensure adequate cooling and EMI containment. RPMs The E1200 system requires the installation of at least one RPM, although two are recommended for redundancy. RPMs are designed to be installed in either the center R0 or R1 slots.

Installing Line Cards and RPMs
At a minimum, the E1200 requires one RPM and one line card to operate.
CAUTION:
Any slot not filled with a line card or RPM must be filled with a blank to ensure adequate cooling
and EMI containment.
RPMs
The E1200 system requires the installation of at least one RPM, although two are recommended for
redundancy. RPMs are designed to be installed in either the center R0 or R1 slots. Since FTOS searches
for an RPM in slot 0 first, Force 10 recommends you install your RPM in slot 0 when only running with
one RPM. 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

provides more information on the second RPM.
The RPM Major and Minor alarm LEDs are controlled by software which sets the threshold levels for
triggering the different stages of alarms.
Line Cards
Your E1200 configuration requires a minimum of
one
line card. Line cards are hot-swappable. The line
card ports provide external interface functions for connections to other systems (for example, a router or
switch). Each line card has an onboard CPU for line card management which updates packet forwarding
information, obtains statistical information, and performs synchronization tasks with the RPM, as well as
Dell Force10 custom-built ASICs, which enable line-rate forwarding.

starting from 0 (see
