Install SCU in MX2820 Shelf

INTRODUCTION

This procedure provides step-by-step instructions to unpack, inspect, and install the System
Controller Unit (SCU) in the MX2820 shelf. This procedure also includes steps to power up
and self-test the SCU.
The MX2820 SCU provides the focal point for all management functions carried out by the
MX2820 system, and the SCU has the greatest number of considerations when installing.
The Ethernet interface for the SCU allows Transaction Language 1 (TL1), Telnet, SSH, or
Simple Network Management Protocol (SNMP) management. The SCU can also be accessed
locally or remotely through the DB-25 connector (X.25 connection, RS-232 interface) located
on the MX2820 backplane.

Communication sessions

There is one session reserved for each of the following communication methods:
• Craft
• Telnet
• X.25
• RS-485
• SSH
Additionally, there are ten pool sessions that can connect to any of these entities.

PREREQUISITE PROCEDURES

Obtain all necessary local instructions before proceeding with the MX2820 shelf installation.
All backplane wiring to the MX2820 shelf should be completed before installing the SCU.
