Es2 4G Lm Combination; Table 16: Average Data Rate For One Es2-S1 Ge-8 Ioa Installed With An Es2 4G - Juniper JUNOSE 11.2.X PHYSICAL LAYER Configuration Manual

Copyright © 2010, Juniper Networks, Inc.
The ES2-S1 GE-8 IOA is offered in a halfheight size that enables you to configure it in
either of the two IOA bays that are available for each slot. You can install the ES2-S1
GE-8 IOA in both IOA bays. For more information about installing IOAs, see the E120 and
E320 Hardware Guide.
The ES2-S1 GE-8 IOA has eight ports. 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. Alternatively, the IOA supports up to eight
pairs of copper SFPs.
NOTE: The ES2-S1 GE-8 IOA has a logical port, numbered port 8, that is reserved for
the hardware multicast packet replication feature. For more information, see JunosE
Multicast Routing Configuration Guide .
The ES2-S1 GE-8 IOA pairs with either the ES2 4G line module (LM), ES2 10G LM, and
the ES2 10G ADV LM to provide access services.

ES2 4G LM Combination

For more information about the ES2 4G LM, see "ES2 4G Line Module" on page 78.
When paired with the ES2 4G LM, you can combine the ES2-S1 GE-8 IOA in a slot with
one of the following IOA types:
ES2-S1 OC3-8 ATM IOA
ES2-S1 OC12-2 ATM IOA
ES2-S1 OC12-2 POS IOA
Bandwidth and Line Rate Considerations
Table 16 on page 175 lists the average data rate on the ES2-S1 GE-8 IOA when installed
in E120 and E320 routers with one ES2 4G LM installed.
