ES2 10G LM Combination
When paired with the ES2 10G LM, you can only combine the ES2-S1 GE-8 IOA in a
slot with another ES2-S1 GE-8 IOA.
With a 100 Gbps fabric configuration, the E320 router can accommodate up to 2
combinations of ES2 10G LMs and ES2-S1 GE-8 IOAs. You must install a combination
in either of the turbo slots (slot 2 or slot 4). The 100 Gbps allocates 10 Gbps of overall
bandwidth to each of these slots.
With a 120 Gbps fabric configuration, the E120 router can accommodate up to 6
combinations of ES2 10G LMs and ES2-S1 GE-8 IOAs. You can install a combination
in any of the line module slots, each of which is allocated 10 Gbps of overall
bandwidth.
With a 320 Gbps fabric configuration, the E320 router can accommodate up to 12
combinations of ES2 10G LMs and ES2-S1 GE-8 IOAs. You can install a combination
in any of the line module slots, each of which is allocated 10 Gbps of overall
bandwidth.
Bandwidth and Line Rate Considerations
Each ES2-S1 GE-8 IOA is connected to the ES2 10G LM through a 5 Gbps bus.
Therefore, the aggregate bandwidth of any IOA is limited to 5 Gbps.
Table 19 on page 186 lists the average data rate on the ES2-S1 GE-8 IOA when installed
in E120 and E320 routers with one ES2 10G LM installed.

Table 20 on page 187 lists the average data rate of two ES2-S1 GE-8 IOAs when
installed in E120 and E320 routers with one ES2 10G LM installed.
