Preface
7
The Nortel Ethernet Routing Switch 8300 is a flexible and multifunctional
Layer 2/Layer 3 switch that supports diverse network architectures and
protocols. The Ethernet Routing Switch 8300 provides security and control
features such as Extensible Authentication Protocol over LAN (EAPoL),
Simple Network Management Protocol, Version 3 (SNMP3), and Secure
Shell (SSH). The Ethernet Routing Switch 8300 provides quality of service
(QoS) for a high number of attached devices and supports future network
requirements for QoS for critical applications, such as Voice over IP (VoIP).
This guide is intended for qualified service personnel who need to add or
replace an AC power supply in an Ethernet Routing Switch 8300 Series
chassis. A qualified service person should have appropriate technical
training and experience and be aware of the hazards involved in installing
and replacing customer-replaceable units.
This guide provides information about the AC power supply used in the
Ethernet Routing Switch 8300 Series chassis and instructions for adding
and replacing an AC power supply in the following Ethernet Routing Switch
8300 Series chassis models:
•
Ethernet Routing Switch 8306 chassis
•
Ethernet Routing Switch 8310 chassis
Command line interfaces
See the following sections for information about the CLI and the NNCLI.
NNCLI command modes
The NNCLI has four major command modes, listed in order of increasing
privileges:
•
User EXEC
•
Privileged EXEC
•
Global configuration
•
Interface configuration

8 Preface
Each mode provides a specific set of commands. The command set of
a higher-privilege mode is a superset of a lower-privilege mode. That
is, all lower-privilege mode commands are accessible when using a
higher-privilege mode.
The command modes are as follows:
•
User EXEC mode
This is the initial mode of access. By default, the User Access
Verification Password for this mode is empty, and password checking
is disabled. The password can be changed (and password checking
enabled) by the system administrator in Global configuration mode.
Once the password is changed, it is activated immediately.
•
Privileged EXEC mode
This mode is accessed from the User EXEC mode. When accessing
this mode, you are prompted to provide a login name and password.
The login name and password combination determines your access
level in the Privileged EXEC mode and other higher modes.
•
Global configuration mode
This mode allows you to make changes to the running configuration. If
the configuration is saved, these settings survive reboots of the switch.
•
Interface configuration mode
This mode allows you to modify either a logical interface, such as a
VLAN, or a physical interface, such as a port/slot.
From either the Global configuration mode or the Interface configuration
mode, all the configuration parameters (both global and interface) can be
saved to a file. The default name for the configuration parameters file is
config.cfg. Alternative filenames can also be used.
Table 1 "NNCLI command modes" (page 9) lists the NNCLI command
modes, the prompts for each mode, the abbreviated name for each mode,
and how to enter and exit each mode.
Prompts are expressed in this table using the format ERS-8300:5; however,
prompts returned from your switch typically reflect the specific chassis you
use. For example, if you use the 8310 chassis, the prompts use the format
ERS-8310:5. Prompts can be customized, also, using the NNCLI command
snmp-server name <prompt>.

Accessing the NNCLI
When you first power up the Ethernet Routing Switch 8300, the default
interface is the Ethernet Routing Switch 8300 CLI. To switch from the CLI
to the NNCLI, you must change the NNCLI boot flag to true and save the
boot configuration file using the following commands:
ERS-8310:5# config boot flags nncli true
ERS-8310:5# save boot
You must reboot the switch for this change to take effect. After you reboot
the switch, access the NNCLI using Telnet, rlogin, or the local console port.
You can log in to the switch using your password and the default privilege
password nortel.
Use the following commands to:
•
log in to the software using the default user name and password
•
access Global Configuration mode
Login: xxxxx
Password: xxxxx

Returning to the CLI
The config.cfg file for the CLI and the config.cfg file for the NNCLI are not
compatible. If you decide to change the CLI mode to NNCLI, or the reverse,
you must use the config.cfg file for the selected mode.
To switch from the NNCLI to the CLI, enter the following commands:
ERS-8310:5(config)# no boot flags nncli
ERS-8310:5(config)# exit
ERS-8310:5(config)# save boot
You must reboot the switch for this change to take effect.

Power supplies
The Ethernet Routing Switch 8306 and 8310 chassis have three bays for
power supplies. Use the AC power supply for AC input power. The following
figure shows an Ethernet Routing Switch 8301AC power supply. The
nominal input voltage range for the 8301AC power supply is 100-120 VAC
and 200-240VAC, however, the output power is limited to 1140 W maximum
at 100-120 VAC nominal input voltage conditions. To obtain full output
power (1770 W), you must connect the 8301AC power supply to a 200-240
VAC nominal input voltage source.

The Ethernet Routing Switch 8300 chassis ships with no installed power
supplies. Install the first power supply in the leftmost bay. Power supply
bays are logically numbered 1, 2, and 3 left to right as viewed from the front
of the chassis for the 8306 and 8310.
Do not install the 8301AC power supply and the 8302AC power supply
within the same chassis. This configuration is not supported.
For the 8306 and 8310 chassis, the number of power supplies that you need
to install—1, 2, or 3—depends on the following:
•
the number of modules installed in the chassis
• PoE requirements
•
whether you want an optional redundant power supply or not
Table 3 "Recommended 8301AC/8302AC power supplies" (page 15) lists
the number of 8301AC or 8302AC power supplies to install based on the
number of installed modules and your power supply redundancy choice.
To provide the required PoE for powered devices (PDs), use Table 4
"8306/8310 chassis available system power" (page 16) to determine the
source input power (100-120 VAC or 200-240 VAC) and the number
of power supplies. For the input power specifications for each of the
modules, see Nortel Ethernet Routing Switch 8300 Installation — Modules
(NN46200-305).

configuration
Page 16
16 Power supply installation
Note the following information:
•
If a power supply fails when you have a redundant power supply
installed, the Ethernet Routing Switch 8300 continues to operate with
no interruption of service. The chassis will continue to supply the same
module and PoE output power with the remaining power supplies. A trap
and syslog message will indicate that the configuration is non-redundant.
• Nortel recommends that you operate the Ethernet Routing Switch 8300
in a redundant configuration at all times to ensure maximum network
up time.
•
Nortel recommends that you install each power supply on its own
dedicated branch circuit. When you plug the power cord for each power
supply into a separate AC circuit, the redundant power supply also
provides protection against the disconnection or failure of an individual
branch circuit or power supply failure.
•
If you have installed a redundant power supply, power available for PoE
is always determined on an N+1 redundancy. If you have 1 or 2 power
supplies in the chassis, you will be allocated PoE power equivalent to
one power supply. If you have 3 power supplies in the chassis, you will
be allocated PoE power equivalent to 2 power supplies.

Removing and installing a power filler panel 17
Removing and installing a power filler panel
A power filler panel maintains the proper cooling airflow in the Ethernet
Routing Switch 8300 Series chassis. If you remove a power supply from the
Ethernet Routing Switch 8300 Series chassis without replacing it, you must
install a power filler panel. When you install a power supply, you must first
remove the power filler panel from the power bay.
To remove a filler panel:
Step Action
1
Using a Phillips screwdriver, loosen the two captive screws that
fasten the power filler panel to the chassis until the screws are free
of the threads in the chassis frame.
2
Pull the power filler panel out of the Ethernet Routing Switch 8300
Series chassis.
Save the power filler panel in case you need to operate the Ethernet
Routing Switch 8300 Series chassis with a power supply removed.
To install a power filler panel:

Installing the AC power supply
Install the AC power supply to provide AC power for components.
—End—
Do not install the 8301AC power supply and the 8302AC power supply
within the same chassis. This configuration is not supported.
When you first install a 8000 Series chassis that requires two power
supplies, you must turn on both power supply units within 2 seconds of
each other. If you wait longer to turn on the second power supply, both
power supplies shut down. To correct this condition, turn off both power
supplies, wait at least 30 seconds, and then turn on both power supplies
again within 2 seconds.
DANGER
Due to high-energy hazards of working with components of greater
than 240 VA, only qualified service personnel are permitted to
install and replace Ethernet Routing Switch 8300 components.
To install an AC power supply:
