Hardware installation
This chapter describes installing a FIM-7920E interface module into a FortiGate-7000 chassis.
Installing QSFP28, QSFP+, SFP+, and SFP transceivers
You must install QSFP28 or QSFP+, transceivers into the FIM-7920E front panel C1 to C4 fabric channel
interfaces before connecting them to 100Gbps or 40Gbps networks (10Gbps networks if splitting interface into
four 10GBASE-SR interfaces). You can install the transceivers before or after inserting the FIM-7920E module
into a chassis.
You must install SFP+ transceivers into the FIM-7920E M1 and M2 interfaces before connecting them to 10Gbps
networks. The FIM-7920E ships with two 10GBASE-SR SFP+ transceivers. You can also configure the M1 and
M2 interfaces to operate at 1Gbps and install SFP transceivers. You can install these transceivers before or after
inserting the FIM-7920E board into a chassis.
You can install the following types of transceivers for connectors M1 and M2:
l
10GBASE-SR SFP+ (10Gbps)
l
10GBASE-LR SFP+ (10Gbps)
l
1000BASE SFP (1Gbps)
The M1 and M2 interfaces are used for heartbeat, session sync, and management
communication between FIM-7920Es in different chassis. This communication
requires 10 Gbps connections so, even though it supported, the M1 and M2 interfaces
should not changed to 1000Base SFP 1Gbps interfaces.
To install transceivers
To complete this procedure, you need:
l
A FIM-7920E
l
Transceivers to install
l
An electrostatic discharge (ESD) preventive wrist strap with connection cord
FIM-7920Es must be protected from static discharge and physical shock. Only handle
or work with FIM-7920Es at a static-free workstation. Always wear a grounded
electrostatic discharge (ESD) preventive wrist strap when handling FIM-7920Es.
Handling the transceivers by holding the release latch can damage the connector. Do
not force transceivers into their cage slots. If the transceiver does not easily slide in
and click into place, it may not be aligned correctly. If this happens, remove the
transceiver, realign it and slide it in again.
