8683POSM module 57
To operate, each module requires at least one of the following MDAs:
• 1-port OC-12c/STM-4: SMF or MMF using SONET media
• 2-port OC-3c/STM-1: SMF or MMF using SONET media
The 8683POSM module supports a mixture of OC-3c/STM-1 and
OC-12c/STM-4 lines. For example, you can install an OC-12c/STM-4
MDA in the first bay and OC-3c/STM-1 MDAs in the two remaining bays.
This module supports up to six I/O OC-3c/STM-1 lines and up to three I/O
OC-12c/STM-4 lines.
The 8683POSM module has an online LED that indicates overall status for
the module.
"8683POSM module LED" (page 57) describes the online LED.

See Using the 8683POSM Module (209564-C) for a description of how to
configure the 8683POSM module using the command line interface (CLI)
or Device Manager.
The 8683POSM module is an M module and supports up to 128 000 table
entries in its forwarding engine, allowing for large Layer 2 and Layer 3
configurations, including Internet routing tables. For information about table
entry characteristics, see Network Design Guidelines (313197-E).
The Metro Ethernet Routing Switch 8600 system has three hardware
operating modes:
• Default mode (32 000 table entries) supports up to 32 000 hardware
records. This mode supports all modules.
• M mode (128 000 table entries) supports up to 128 000 hardware
records. This mode supports M modules only.
• R mode supports up to:
— 256 000 IP routes
— 64 000 MAC entries
— 32 000 ARP entries
This mode supports R modules only.
