(SERIES CB)) line cards are interchangeable between the C7008/C300 and
C7004/C150 only if the chassis is running Dell Networking OS version
7.6.1.0 or later.
• To control airflow for adequate system cooling, personal safety, and EMI
containment during operation, blanks are required in empty slots. Yoou must
install all chassis slots with operational modules or blanks. Always replace
cards and blank panels immediately.
Installing RPMs and Line Cards
WARNING: Always wear an ESD-preventive wrist or foot-heel ground strap
when handling RPMs or line cards. Place RPMs and line cards on an antistatic
surface when they are not installed. ESD damage can occur when components
are mishandled.
CAUTION: Unlock the levers before inserting the line card into the chassis.
Fully engage the locking mechanism after the card has been inserted; not
doing so might damage the card below it when you insert that lower card.
NOTE: The fan tray face panel has slot number markings for the RPMs and line
cards. To simplify RPM and line card installation, insert the fan tray before the line
cards.
Step Task
1 Extend the left and right card levers by first pressing gently down on the
thumb tabs in the ejector levers and then pulling the ejector levers
simultaneously until they are in the open position.
2 Hold the card assembly by the metal carrier edges. Avoid touching the
printed circuit board and connector pins.
3 Align the card with the guide, and gently slide it into any line card slot
until the card is about halfway into the slot.
NOTE: To determine which slots are for the RPMs and which are
for the line cards, use the markings on the fan tray.
4 Continue sliding the card until you feel the connectors engage with the
chassis backplane.
