Card slots in the SmartEdge 1200 chassis are numbered sequentially from left to right as you face the front
of the chassis; see Figure 4-16.
Figure 4-16
SmartEdge 1200 Card Slots
Observe the following configuration rules when installing the cards:
• Slots 7 and 8 are reserved for controller cards only.
• Optical, Ethernet, and the other Gigabit Ethernet cards, with the exception of the 20-port GE1020 traffic
card, can be installed in any of slots 1 to 6 and 9 to 14; because the 20-port GE1020 card requires two
adjacent slots, the slot range is 1 to 5 and 9 to 13.
• The XCRP4 Controller card does not support channelized SONET or SDH traffic cards.
Table 4-2 summarizes the slot assignments for the SmartEdge 1200 cards.
Note
When you first power on the system, the active controller card is in slot 7. Thereafter, the slot
changes whenever a switchover occurs.
Note
The breakout cables for an FE-GE traffic card can impinge on the cable routing for other cards
in the chassis. When selecting a slot for an FE-GE card in a SmartEdge 1200 chassis, choose
one of the outer slots on the left side of the chassis.
