7210 SAS-X Introduction and Features

SR72033A

7210 SAS-X Introduction and Features

7210 SAS-X supports line-rate switching and provides better service scale along with richer QoS
capabilities, useful for first level of access ethernet aggregation in small and medium access
networks.

The 7210 SAS-X has one 10/100BASE-TX management port for dedicated management access.

Figure 1: 7210 SAS-X Front Panel

The 7210 SAS-X includes the following features:

• 24 100/1000 SFP ports and 2 10G XFP ports

• One RJ-45 management port for firmware upgrade or system ma nagement

• One RJ-45 console (RS-232 interface) connector for device management

• Embedded SR OS

• Compact size: 2.0RU height, 19-inch rack-mountable metal enclosure, 11-inch depth
(ETSI)

Page 12 7210 SAS-X Installation Guide

Switch Architecture

The 7210 SAS-X employs a wire-speed, non-blocking switching fabric. This permits simultaneous
wire-speed transport of multiple packets at low latency on all ports. The switch also features full­duplex capability on all ports, that effectively doubles the bandwidth of each connection.

Network Management Options

This switch contains a comprehensive array of LEDs for at-a-glance monitoring of network and
port status. It also includes a management agent that enables you to configure or monitor your
switch using its CLI, or by using SNMP applications.

To manage the switch, you can make a direct connection to the console port (out-of-band Ethernet
management port) or you can manage it by using a network connection (in-band SFP or XFP
ports) using Telnet/SSH or SNMP-based network management software.

7210 SAS-X Overview

The management port provides a dedicated management channe l that operates outside of the data
transport network. This makes it possible to reconfigure or troubleshoot the switch over either a
local or remote connection to the management port when access using the data channel is not
possible or deemed insecure.

Hardware Description

Ethernet Interfaces

The 7210 SAS-X provides 24 100/1000 SFP ports. Each port can be used for a direct connection to
a subscriber’s Customer Premises Equipment (CPE), or as an uplink to another aggregation node.
The 7210 SAS-X supports 10/100/1000 Base-T copper SFPs. In addition, the 7210 SAS-X
supports 2 x 10G XFP ports. This port can serve as a network uplink to another aggregation node
or as an access port to a subscriber's CPE.

Management Port

The management port provides a dedicated management interface that is segregated from data
traffic crossing the other ports.

Console Port

The console port uses an RJ-45 connector with serial pinouts (see Table 10) that ena ble s a
connection to a terminal for performing switch monitoring and configuration operations. The
terminal may be a PC or workstation that is running terminal emulation software, or a terminal
configured as a Data Terminal Equipment (DTE) connection. A null-modem wired serial cable is
supplied with the switch for connecting to this interface.

The serial port configuration requirements are as follows:

• Default Baud rate – 115200 bps

• Character Size – 8 Characters

• Parity – None

• Stop bit – One

• Data bits – 8

• Flow control – none

Hardware Description

Alarm Interface Port

The alarm interface port is a D-type 15-pin connector that supports a critical alarm output, a major
alarm output, a minor alarm output, and three alarm inputs. When your system has an alarm, the
CPU will drive the alarm relay to issue the alarm output and turn on the associated alarm LED. If
you push the alarm cut off (ACO) button, the relay will be released but the LED will stay on until
the alarm is cleared.

The system signals the appropriate alarm output for the following events:

• Fan failure - Critical alarm is raised.

• One Power Supply Failure - Critical alarm is raised. The critical alarm is cleared and a
major alarm is raised if the failed power supply is removed).

• Chassis temperature threshold exceeded - Major alarm is raised.

The system also supports three alarm inputs. The input voltage range is from 24V to 48V. If an
alarm input is active, the CPU will process it, output it to the CLI, and issue an SNMP trap. An
alarm input can also be configured to drive the appropriate alarm output pin. Please refer the
System Basics user guide for more details on configuring the alarm inputs.

See Table 3 for the alarm interface port pinouts.

Power Modules

The 7210 SAS-X provides two power module options: -48V DC and universal AC. See Figure 3
for an illustration of the power modules.

For specifications on the power supply modules and external input power requirements, see
"Connecting to a Power Source" on page 36 and "Appendix A: Specifications" on page 65.

LED Condition Status

Input / Output Green DC or AC power is functioning normally.
Output Red AC or DC power is not functioning normally.
Input Off / Red External power not connected or has failed.

Note: When AC and DC power supply is used
simultaneously, and the AC power supply
functions normally while there is no DC input
provided, then the DC power supply input
status LED glows Red.

7210 SAS-X Overview

The Input LEDs on the left indicate the status of external power. The Output LED on the right
indicates the status of the internal power conversion process.

Note: You must use AC and/or DC power supplies with your 7210 SAS-X. AC and DC power

supplies can be used simultaneously.

USB Port

The USB port is reserved for future use.

Fan Tray

A hot-swappable fan tray on the right side of the front panel contains three fans that provide
cooling for the chassis. See Figure 4 for an illustration of the fan tray.

The fans are controlled by the system software, and their speed is set according to the
environmental temperature surrounding the switch. Allow at least three inches of clearance on the
sides of the rack to ensure proper airflow intake cooling system. The fan trays must be in place
before the chassis is powered on.
