Using Copper and Fiber SFP Transceivers

SFP+ Status and Activity LEDs

68
When you configure the 10-Gigabit Ethernet ports
you can use optical fiber SFP transceivers in any of the ports. However, copper SFP
transceivers are restricted to the lower two rows. See

Figure 45: Supported Placement for Copper and Fiber SFP+ Transceivers

CAUTION: Stacking three copper SFP transceivers in a column can cause
damage to the line card.
Because 1 Gbps copper SFP transceivers are physically larger than optical SFP
transceivers, there is insufficient room for 3 copper SFP transceivers to be stacked. Use
the top row only for optical SFP transceivers. You can stack copper transceivers in the
bottom two rows. Ports are arranged belly-to-belly. Stacking three SFP transceivers in
a column can damage the line card. For the recommended configuration, see
Figure 46 on page 68.

Figure 46: Belly-to-Belly SFP Transceivers

Recommended configuration
All status and activity LEDs for the SFP+ ports are located between the second and third
rows of SFP+. The up arrow, circle, and down arrow indicate the row of the status. A
bi-color LED indicates the status and activity. See
Table 27 on page 69.
