4-Port Fast Ethernet ePIM
You can install 4-Port Fast Ethernet ePIMs in any of the high-speed slots, as follows:
J4350—Install up to two 4-Port Fast Ethernet ePIMs in slots 3 and 6.
J6350—Install up to four 4-Port Fast Ethernet ePIMs in slots 2, 3, 5, and 6.
NOTE: For 4-port Fast Ethernet ePIMs, if you apply a CoS scheduler map on outgoing
(egress) traffic, the router does not divide the bandwidth appropriately among the
CoS queues. As a workaround, configure enforced CoS shaping on the ports.
The 4-Port 10/100-Mbps Fast Ethernet ePIM, shown in Figure 19, has
four physical Fast Ethernet ports.
