Table 9 lists physical and logical density maximums for the E120 router and the
E320 router. The following notes are referred to in Table 9:
1. Wire rate indicates the port density that supports maximum (wire-rate)
performance. Oversubscribed indicates the port density possible if you are
willing to accept less than wire-rate performance by oversubscribing the
available fabric bandwidth.
2. With a 120 Gbps configuration on the E120 router, you can install up to 6
combinations of ES2 10G Uplink LMs or ES2 10G LMs in slots numbered 0-5.
You can install a maximum of 6 active ports and 6 redundant ports at any time.
With a 100 Gbps fabric configuration on the E320 router, you must install the
ES2 10G Uplink LM or the ES2 10G LM in either of the E320 router turbo slots (2
and 4). When the ES2 10G Uplink LM or the ES2 10G LM is installed in slot 2 or
slot 4, you cannot install another line module in slot 3 or slot 5. In this case, you
can only install the ES2 4G LM in slots 0–1 and 6–11; therefore, the maximum
number of ports and the forwarding performance per chassis is reduced for the
IOAs that pair with the ES2 4G LM.
With a 320 Gbps fabric configuration on the E320 router, you can install up to
12 combinations of ES2 10G Uplink LMs or ES2 10G LMs in slots numbered 0-5
and 11-16. You can install a maximum of 12 active ports and 12 redundant
ports at any time.
