Installation Guide

External compact ash
MR2 management modules do not contain an auxiliary ash slot. Instead, they contain a 2 GB internal compact ash card and an
external compact ash drive. MR2 management modules come with a factory installed compact ash card in the external compact ash
slot. The internal compact ash provides greater storage space for image retention, improving the upgrade process.
NOTE
Do not use compact ash cards over 2 GB; they will render the system unstable.The internal compact ash card cannot be
accessed for removal or replacement.
The external compact ash slot allows you to insert a 2 GB compact ash card. If you need to replace or add an additional compact ash
card, contact Extreme technical support.
Console port
The console port is a standard DB-9 serial connector through which you can attach a PC or terminal to
congure the router using the
CLI.
NOTE
The console port interfaces the control plane only. It does not interface the data plane.
10/100/1000 Ethernet port
Management modules contain a 10BaseT, 100BaseTX, or 1000BaseTX auto-sensing, auto-negotiating Ethernet port. This port has an
RJ-45 unshielded twisted pair (UTP) connector.
Typical uses of this port include, but are not limited to, the following:
• Connecting a PC to congure, monitor, and manage the system through a Telnet or SSHv2 connection.
• Connecting to the 10BaseT, 100BaseTX, or 1000BaseTX port for connectivity to your existing management network. You can
then access the router and congure, monitor, and manage the system from a management station.
NOTE
The existing management network into which you can connect the 10/100/1000 Ethernet port must be separate and isolated
from the network over which user packets are switched and routed. For information about the functionality of the management
port, refer to Understanding management port functions on page 196.
For information about connecting a PC to the 10/100/1000 Ethernet port, refer to Attaching a management station on page 171.
The out-of-band management port provides access to a separate system management network, and allows the ability to perform the
following tasks:
• Access the router through SSH, Telnet, the Web management interface, or Extreme Network management software.
• Access a TFTP server to perform system upgrade tasks.
• Congure SNMP polling access.
• Send SNMP traps.
• Send Syslog packets.
• Access the system through RADIUS AAA.
Management module LEDs
The LEDs on all management module models are the same. The following table describes the LEDs on the management module.
