20 Installing the Hardware
Installing RPMs, Line Cards, and SFMs
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. Connect your
ESD strap to the grounding plug located on the front of the chassis. See Figure
2 for ESD strap connector location. After you remove the original packaging,
place RPMs, SFMs, and line cards on an antistatic surface.
CAUTION: Do not supply power to your system until the power supplies and
fan tray(s) are installed and verified, and RPMs, SFMs, line cards, and any
blank panels are installed.
Blank Panels
CAUTION: To avoid a chassis over-temperature condition, install blanks for
RPMs, SFMs, and line card slots not in use. Always replace cards or blanks
immediately.
Blank panels for RPMs, SFMs, 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.
E300
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.
8 Check that the over-current protector (located on the PEM front panel)
is in the OFF position. Energize the remote power source. The Voltage
LED should be green. If it is amber, the -48 VDC and Return cables are
connected incorrectly or are reversed.
