1-Gb SX/10-Gb SR/10-Gb LR Network Module with Hardware Bypass
The following figure shows the front panel of the 1-Gb SX, 10-Gb SR and 10-Gb LR hardware bypass network
modules (FPR4K-NM-6X1SX-F, FPR4K-NM-6X10SR-F, FPR4K-NM-6X10LR-F). This is a single-wide
module that does not support hot swapping. The six ports are numbered from top to bottom, left to right. Pair
ports 1 and 2, 3 and 4, and 5 and 6 to form hardware bypass paired sets.
Bypass LED BP:
• Green—In standby mode.
• Amber, flashing—Port is in hardware bypass
mode, failure event.
• Amber—Port is in hardware bypass mode,
forced.
Network activity LEDs for Pair 1:
• Amber—No connection, or port is not in
use, or no link or network failure.
• Green—Link up, no network activity.
• Green, flashing—Network activity.
