Dual-Port 40GBASE-SR4 Fiber Configurable Bypass NetMod
The dual-port 40GBASE-SR4 fiber configurable bypass configuration uses MPO (Multiple-Fiber Push
On) connector optical transceivers.
You can use the 40G NetMod only in the following 8000 Series models:
•
Firepower 8270 and 8290
•
Firepower and AMP 8360, 8370 and 8390
•
Firepower 8250 and 8260 (must be 40G-capable)
•
Firepower and AMP 8350 (must be 40G-capable)
Caution
If you attempt to create a 40G interface on a device that is not 40G-capable, the 40G interface screen on
its managing Firepower Management Center web interface displays red. A 40G-capable 8250 displays
“8250-40G” on the LCD Panel and a 40G-capable 8350 displays “8350-40G” on the LCD Panel.
You can use this configuration to passively monitor up to two separate network segments. You also can
use the paired interface in inline or inline with bypass mode, which allows you to deploy the device as
an intrusion prevention system on one network.
You can use up to two 40G NetMods. Install the first 40G NetMod in slots 3 and 7, and the second in
slots 2 and 6. You cannot use a 40G NetMod in slots 1 and 4.

40G NetMod Placement
If you want to take advantage of a device’s automatic bypass capability, you must use the web interface
to configure a pair of interfaces as an inline set and enable bypass mode on the inline set.
