SRX5K-MPC3-100G10G Specifications


The SRX5K-MPC3-100G10G (IOC3) is an interface card that provides 100 Gigabit Ethernet and 10 Gigabit Ethernet interfaces, with a Packet Forwarding Engine that provides a 240 Gbps line rate. This interface card is supported on SRX5400, SRX5600, and SRX5800 Services Gateways. See Figure 1.


These cards do not support plug-in Modular Interface Cards (MICs).

All ports on the interface card have dual-color LEDs for reporting link status.

The interface card also supports hot-pluggable optical modules.

If a slot in the SRX5400, SRX5600, or SRX5800 Services Gateway card cage is not occupied by a card, you must install a blank panel to shield the empty slot and to allow cooling air to circulate properly through the services gateway.
