Chassis Slot Numbering and Assignments
The chassis has 32 rear-loaded slots for line cards. This allows for the installation of redundant components and
provides ample space for expanding the system.
There are two rows of slots on the rear of the chassis. The upper row of slots is labeled 17 through 32 from right to left.
The lower row of slots is labeled 33 through 48 from right to left.
Figure 27. Chassis Slot Numbers (Rear)
Important:
The 10 Gigabit Ethernet Line Card is a full-height line card that occupies the upper and lower slots in
the chassis. When referring to installed XGLCs, use the upper slot number only. Slot numbering for other installed half-
height cards is maintained: 17 to 32 and 33 to 48, regardless of the number of installed XGLCs
The following table shows the front slot numbers and their corresponding rear slot numbers.
