Table 22 on page 180 lists the average data rate of two ES2-S1 GE-8 IOAs when installed
in E120 and E320 routers with one ES2 10G ADV LM installed.

Managing High-Density Ethernet
When installed in an E120 or E320 router with any SRP module combination, the overall
data rate for the ES2 10G ADV LM with one ES2-S1 GE-8 IOA is limited to 5 Gbps. The
overall data rate for the ES2 10G ADV LM with two ES2-S1 GE-8 IOAs is limited to 10 Gbps.
In all configurations, the line module can become oversubscribed because of the IOA
available wire rate (8 Gbps).
Currently, flow control using MAC pause frames is disabled on the ES2-S1 GE-8 IOA. The
IOA does not transmit or receive pause frames.
For more information about high-density Ethernet on E Series routers, see “High-Density
Ethernet” on page 187
.
ES2-S3 GE-20 IOA
The E120 and E320 routers support the ES2-S3 GE-20 IOA. Other E Series routers do not
support the ES2-S3 GE-20 IOA.
The ES2-S3 GE-20 IOA pairs with the ES2 10G LM or the ES2 10G ADV LM to provide
Gigabit Ethernet operation through 20 line interfaces.
The ES2-S3 GE-20 IOA is offered in a full-height size that uses both adapter bays. The
IOA is identified by the software as adapter bay 0. For more information about installing
IOAs, see the
E120 and E320 Hardware Guide .
The IOA can use either fiber-optic or copper SFPs. The IOA accepts up to four pairs
(Tx/Rx) of LC-style fiber-optic connectors that support different optical modes and
cabling distances.
The ES2-S3 GE-20 IOA does not support port redundancy.
ES2 10G LM Combination
With a 100 Gbps fabric configuration, the E320 router can accommodate up to 2
combinations of ES2 10G LMs and ES2-S3 GE-20 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.
