2.3.2 Card Cage and Slot Assignment
The device features a four-slot chassis - four front-panel slots for housing blades and four
rear-panel slots for housing the RTMs. The blades in the front-panel slots interface through
a midplane (located in the middle of the chassis) with the RTMs in the rear-panel slots . A
diagram indicating the number of the slots and Power Supply unit is located on the Fan
Tray panel (refer to ''Chassis Cooling System'' on page
35 ). The midplane contains slot
keys (located in the middle of the midplane), which match the appropriate blade or RTM.
This prevents insertion of a blade or RTM in an incorrect slot.
Notes:
•
While the slot keys on the midplane are designed to prevent the insertion
of a blade in an incorrect location, ensure that you don’t force a blade or
RTM into a slot; otherwise, you may damage the blade/RTM or midplane.
