Limitations of 2X100 GE IM
After any QSFP28 100G optics is inserted, it takes approximately 10 seconds for the optics to be detected
and the link to come up. We recommend this time delay for complete initialization and operation.
After inserting the cable or after unshutting the 100G interface, the 100G link may take approximately about
2 seconds to come up.
QSFP-100G-SR4-S and QSFP-100G-LR4-S are the supported optics for 2X100GE IM for the release 16.11.1.
Note
2-Port 40 Gigabit Ethernet QSFP Interface Module (2x40GE) (A900-IMA2F)
The dual port 40 Gigabit Ethernet interface module supports the 40 Gigabit Ethernet port. The 40GE interface
is supported using QSFP+ optics. The figure below shows the interface module.

8/16-Port 1 Gigabit Ethernet (SFP / SFP) + 1-port 10 Gigabit Ethernet (SFP+) / 2-port 1 Gigabit Ethernet
(CSFP) Interface Module (A900-IMA8CS1Z-M)
The A900-IMA8CS1Z-M interface module has the flexibility to support SFP+/SFP/CSFP on the modules as
mentioned below:
• The 8-port 1 Gigabit Ethernet ports can also be used as 16-port 1 Gigabit Ethernet ports Small Form-Factor
Pluggable (SFP) .
• The 1-port 10 Gigabit Ethernet port can also be used as 2-port 1 Gigabit Ethernet ports with Small
Form-Factor Pluggable (SFP+).
