Electrostatic discharge

This section provides information and procedures to prevent electrostatic discharge during
installation.

Preventing electrostatic discharge damage

Electrostatic discharge (ESD) is a discharge of stored static electricity that can damage
equipment and impair electrical circuitry. Electrostatic voltages can result from friction

Installation November 2010 17

Installing the Avaya Ethernet Routing Switch

including, pulling cabling through conduits, walking across carpeted areas, and building static
charge in clothing. When you improperly handle electronic components, ESD damage occurs
and can result in complete or intermittent failures. While networking equipment is commonly
designed and tested to withstand common mode ESD events, voltage can sometimes
discharge to some connector pins, which can potentially damage the networking equipment.

Caution:

To protect the Avaya Ethernet Routing Switch against ESD damage, take the following
measures before you connect data cables to the device:

• Always use antistatic wrist straps. Make sure you adjust the strap to provide good skin
contact.

• Ensure that you properly ground work surfaces and equipment racks for protection
against electrostatic discharge. You must connect the common point to the building
ground wire. In a properly wired building, the nearest reliable ground is typically at the
electrical outlet.

• Avoid contact between equipment and clothing. The wrist or ankle strap protects only
the equipment from ESD voltages on the body; ESD voltages on clothing can still cause
damage.

• Avoid touching any connector pins.

• Do not remove the wrist or ankle strap until the installation is complete.

Preventing electrostatic damage in new cable installations

With new cable installations, Avaya recommends that you use an ESD discharge cable to
reduce the potential for damage from static, that can build up in cables. The following figure
illustrates an ESD cable.

Figure 1: Job aid

To install the ESD discharge cable, perform this procedure.

18 Installation November 2010

1. Connect the ground lug on the ESD discharge cable to a safe and suitable earth
ground.

2. Connect all RJ-45 cable connectors to the female RJ-45 connector of the ESD
discharge cable for at least 5 seconds, and then connect each RJ-45 cable
connector to the switch.

3. Leave cables connected to the networking equipment. After you connect cables to
networking equipment, the cables do not build up charge.

Environmental requirements

The following table provides the environmental requirements for the individual switches in this
series. Ensure that the area where you install the switch and where it operates meets these
requirements.

Set IP parameters for the Avaya Ethernet Routing Switch
4500 Series

After an Avaya Ethernet Routing Switch 4500 Series switch starts up and initializes all software
modules, it begins switching operations.

To manage the switch using Telnet or SNMP, or to perform TFTP operations, you must set
certain IP parameters. Also, if you intend to connect the switch to a stack configuration, you
must assign additional parameters to ensure proper stack operation.

You must configure the following IP parameters for initial switch setup:

• IP address of the switch or stack

• subnet mask

• gateway address

the appropriate IP address.

<subnet_mask> The subnet mask to be used.

<gateway_address> The default gateway address to be used.

The IP configuration is now complete.

To continue configuration, use the appropriate CLI commands.

To disconnect from the switch, use the logout command.

Set IP parameters using IP.CFG file on a USB memory device

If the switch does not obtain an IP address through BootP, you can load the IP address and
optionally new switch software and configuration from the USB memory device using the ip.cfg
file.

Note:

The file name, ip.cfg, is case-insensitive.

See also Universal Serial Bus (USB) ports on page 31

If a properly formatted file exists on a USB port, the switch uses that ip.cfg as the first option,
rather than the last. You can specify one or more of the optional parameters in the ip.cfg file.
All of the parameters are optional.

The following table describes the ip.cfg file parameters:

48 Installation November 2010

Mask <xx.xx.xx.xx> Specifies the network mask. Example: 255.255.255.0

Gateway <xx.xx.xx.xx> Specifies the default gateway. Example:

181.30.30.254

SNMPread <string> Specifies the SNMP read community string.

Example: public

SNMPwrite <string> Specifies the SNMP write community string.

Example: private

VLAN <number> Specifies the management VLAN-ID. Example:

USBdiag <string> Specifies the filename of the diagnostic image to load

from the USB. Example: ers4500/
ers4500_5.1.0.4.bin

USBascii <string> Specifies the filename of the ASCII config file to load

from the USB. Example: customer1.cfg

USBagent <string> NEXTIP,
NEXTMask, and NEXTGateway

Specifies the filename of the agent image to load from
the USB and specifies IPs for next boot. Example:
ers4500/ers4500_5.2.0.0.img

Note:

If you download an ASCII file or diag/image with an Ip.cfg file, the specific ASCII file or diag/
image must be present on the usb device.

The ip.cfg file loads information from the ASCII configuration file in order of precedence. For
example, if you have an ip.cfg file with the following commands:

USBascii ip.txt
IP 181.30.30.113
Mask 255.255.255.0
Gateway 181.30.30.254

The stack IP becomes 181.30.30.113 no matter what IP address is in the ip.txt file.

If you have an ip.cfg file with the following commands:

IP 181.30.30.113
Mask 255.255.255.0
Gateway 181.30.30.254
USBascii ip.txt

The stack IP will be the IP address defined in the ip.txt file.

Installation November 2010 49

Installing the Avaya Ethernet Routing Switch

Note:

The ip.cfg file runs only on a base or stand-alone unit. The file cannot be more than 4096
bytes or contain more than 200 lines.

The following figure shows an example of an ip.cfg file.

Figure 15: ip.cfg file example

If the ip.cfg file specifies an image or agent code, the switch loads the software, even if the
same version is already installed on the switch. Ensuring that the appropriate software is
always upgraded on the units is the correct operation of ip.cfg.

Use the factory default command to reset the switch to the factory default after you insert the
USB memory device in the USB port. The USB memory device must contain the properly
formatted ip.cfg file in the root directory.

Resetting the switch to default settings

Perform this procedure to reset the switch to the factory default settings with the ACLI.

1. Enter boot default.

2. Enter y to confirm the reset.

The Avaya Ethernet Routing Switch 4500 restarts with factory default settings and
attempts to read the ip.cfg file from an installed USB drive within three minutes. The
Avaya Ethernet Routing Switch 4500 banner page appears while the switch
retrieves the ip.cfg file.

Important:

If you have a console connected to the switch / stack, then while the system retrieves the
ip.cfg file from the USB memory device, the Avaya banner page appears. If you use the
serial console while the system is restarting or within the first few minutes after booting, then
the switch will not load the IP.CFG file. If you want the switch to load the configuration using
IP.CFG, Avaya recommends not interact with the switch via the console port for a period
of 3 minutes after booting the switch or stack. This is necessary to give the switch sufficient
time to load the IP.CFG file and take appropriate actions. If the switch is also performing an

50 Installation November 2010

Set IP parameters for the Avaya Ethernet Routing Switch 4500 Series

automated update of the software, then this period of time will be increased as the switch
will need to perform an automatic reboot during the IP.CFG process to load the designated
software.

Checking the status of the download

Perform this procedure to check the status of the download three minutes after the Avaya
banner page appears.

Press CTRL and y keys together.

Two possible responses indicate a pass or fail status.

• Pass: The system opens the first page of menu.

• Fail: The system prompts you for an IP address.

You can confirm the successful download with the show ip command. If the USB ip.cfg file
download succeeded, all parameters read from the ip.cfg file show as present in the switch
and become part of the runtime configuration. If there is an error parsing the ip.cfg file, a log
entry provides an indication of the error encountered.

If you have disabled autosave, then save the configuration with the ACLI command, copy
config nvram. After the successful ip.cfg file download from the USB memory device, you
can manage the switch through Telnet and SNMP.

If you load any diagnostic or agent images with ip.cfg, the diagnostic or agent images need to
be on the same USB memory device. Restart the system after you download the ip.cfg files.
To ensure that diagnostic and agent image downloaded successfully, check in the system log or
audit log. If the operation is successful, restart the switch or stack to display the new diagnostic
and agent images.

If you download an ASCII file, you must enter the settings after the download. You do not need
to restart the switch or stack if you download an ASCII file.

Set IP parameters using bootp

The Avaya Ethernet Routing Switch 4500 Series switches are configured to obtain a
management IP address using BOOTP by default

If the switch is connected to the network and an appropriate bootp server is configured, then
the server assigns an IP address to the switch.

To view the assigned and in-use IP addresses, connect to the switch console and enter the
show ip command.

Setting IP parameters using the Web-based Management Interface

To set IP parameters using the Web-based Management Interface, perform the following
procedure.

Prerequisites Ensure that the switch has an IP address.

1. Connect a computer to the switch through a data port using a standard RJ-45

network cable.

2. Open a Web browser on the attached computer and enter the IP address of the

switch in the following format: http://<nnn.nnn.nnn.nnn>. The main screen of the
Web-based Management Interface appears.

3. Choose Configuration > IP from the menu. The following figure appears.

4. Use the fields on the IP configuration screen to configure the IP parameters. All

fields are divided into three columns: Configurable, In Use, and Last BootP. Use
the Configurable column to configure a new value for the field. The In Use column
represents the current value used by the switch, and the Last BootP column
supplies a value assigned to the field by a BootP request. The following table lists
and describes the fields on the IP configuration screen.

Avaya Ethernet Routing Switch 4500 series stacking

The Avaya Ethernet Routing Switch 4500 Series provides fail-safe stackability. You can
connect up to eight 4500 Series devices in a stack to provide uninterrupted connectivity for up
to 400 ports. You can manage the stack as a single unit.

Stack connector

The stack connector is a component of the Avaya Ethernet Routing Switch 4500 Series back
panel and consists of the Unit Select switch, Cascade Down connector, and Cascade Up
connector. The stack connector is illustrated in the
diagram.

Figure 16: Stack connector on page 54

Installation November 2010 53

Installing the Avaya Ethernet Routing Switch

Figure 16: Stack connector

Unit Select switch

Use the Unit Select switch to designate a switch in the stack as the base unit. Slide the Unit
Select switch to the right to designate a switch as the base unit. You can designate only one
switch in a stack as the base unit; that is, with the switch in the base unit position. For all other
switches in the stack, the Unit Select switch must be in the left position.

The base unit designation for a switch appears on the front panel LED display. See

Switch LED state indicators on page 42.

Cascade Down connector

Use the Cascade Down connector to connect a switch to the next unit in the stack through a
cascade cable. Connect the other end of the Cascade Down cable to the Cascade Up
connector of the next switch in the stack. A return cable from the Cascade Down connector of
another unit to the Cascade Up connector of the first unit completes the stack connection. See

Figure 17: Simplified stacking diagram on page 55 and Figure 18: Connecting cascade
cables on page 56.

Table 14:

Important:

To create a stack connection, order the appropriate Avaya Ethernet Routing Switch 4500
Series cascade cables to ensure fail-safe stacking. A 1.5 foot stacking cable is included with

54 Installation November 2010

the switch. For stacking three or more units (maximum eight units per stack), order the 5
ft, 10 ft, 14 ft or 16.4 ft. cables as applicable.

Cascade Up connector

The Cascade Up connector provides an attachment point that accepts a cascade cable
connection from another unit in the stack. A return cable from the Cascade Down connector
of one switch to the Cascade Up connector of an adjacent switch completes the stack
connection. See Figure 17: Simplified stacking diagram on page 55 and Figure 18:

Connecting cascade cables on page 56.

Figure 17: Simplified stacking diagram on page 55 illustrates a simple, two-switch stack

connection.

Initial installation unit number assignment

When you install the stack, the software automatically determines the physical order of all units
in the stack according to the position of the base unit within the stack. Thereafter, the individual
units maintain their original unit numbering, even if you change the position of one or more
units in the stack.

For example, when you initially power the stack, the base unit becomes unit 1 and the unit that
the base unit connects to (across the Cascade Down cable) becomes unit 2. The next unit is
designated as unit 3, this continues until the maximum stack configuration (up to eight units)
is reached. If another unit in the stack is designated as the base unit, the new base unit keeps its
originally designated unit number in the stack.

Stack MAC address

When a switch participates in a stack configuration, stack initialization automatically assigns
a stack MAC address. The stack MAC address is the base unit MAC address plus 1. If another

56 Installation November 2010

unit in the stack is assigned as the base unit, the new stack MAC address is the MAC address of
the new base unit plus 1. The original stack IP address still applies to the new base unit.

Temporary base unit

If an assigned base unit fails, the next unit in the stack order automatically becomes the new
temporary base unit. The LED display on the front panel of the temporary base unit changes
to a steady amber state to indicate the change. When this happens, use the Unit Select switch
to designate the temporary base unit as the base unit until you repair or replace the failed base
unit.

You must designate a base unit because the automatic failover is only a temporary safeguard
and, if the original unit rejoins the stack, it does not resume base unit status. Also, if the stack
configuration loses power, the temporary base unit does not resume base unit status when
power is restored.

Important:

If the temporary base unit is not assigned as the new base unit, and the temporary base unit
fails, the next unit in the stack order becomes the temporary base unit. This process
continues after successive failures until only two units are left in the stack.

Avaya Ethernet Routing Switch 4500 series stacking

Redundant cascade stacking

The Avaya Ethernet Routing Switch 4500 Series allows a stack of up to eight units into a dual­path cascade stack. If any single unit fails, or if a cable is accidently disconnected, other units in
the stack remain operational.

In addition to increasing bandwidth, the software uses the cables to provide two paths between
units. If one path is interrupted, the data travels over the remaining path at half the normal
interswitch bandwidth.

Figure 19: Redundant cascade stacking on page 58 shows a typical example of a stack

configuration reacting to a failed connection in the stack configuration.

Installation November 2010 57

Installing the Avaya Ethernet Routing Switch

Figure 19: Redundant cascade stacking

4. Cascade Cable

In the example, the following occur:

• Unit 3 becomes nonoperational due to a unit failure, cable disconnection, or a loss of
power.

• Units 2 and 4, directly upstream and downstream from Unit 3, sense the loss of link signals
from unit 3. The software directs all the data to traverse the remaining path.

• The Cascade Down LED for Unit 2 and the Cascade Up LED for Unit 4 turn amber to
indicate an error.

• The remaining stack units remain connected and continue to operate.

Replacing or adding a stack unit

To replace a failed stack unit or insert a new unit into a stack, perform this procedure.

Important:

Automatic Unit Replacement (AUR) for both configuration and software is enabled for all
Avaya Ethernet Routing Switch 4500 Series platforms and software releases. This means
that the agent code image, on a replacement unit, is automatically upgraded or downgraded

58 Installation November 2010

Stack configurations

to match the software running on the stack. In addition, when a like-for-like replacement of
a failed unit occurs, any port-specific configuration is restored .

1. Remove the failed switch from the stack.

2. Obtain a like-for-like replacement switch.

3. With the new unit turned off, physically insert the new unit in the stack and reconnect
the stack cables.

4. Turn on the new unit. Depending on the software load on the replacement switch,
it can automatically restart one or two times before joining the stack as a fully
operational member.

5. Check the log file on the stack to ensure that the replacement unit correctly joined
the stack. The log file displays AUR information messages.

If you replace the base unit, remember that the stack has elected a temporary base unit and
the new unit does not automatically assume the base unit status. Configure the new unit as
the base unit, using the Unit Select switch, and reset the Unit Select switches of the other stack
members to nonbase units.

Remove a stack unit

If you remove a unit from the stack (to operate in stand-alone mode), the following switch
configuration settings revert to those configured before the unit became a member of the stack:

• IP address

• Web, Telnet, and SNMP passwords

• SNMP community strings

Stack configurations

Because stack parameters are associated with the base unit, the physical stack order depends
on the base unit position and whether you configure the stack cascade up (stack up) or cascade
down (stack down). This designation depends on the stack cabling arrangement. Avaya
recommends that you use Cascade Down configuration. See

Cascade down

Cascade down on page 59.

In a cascade down configuration, the base unit is located at the top of the stack. The system
automatically numbers the physical units based on the designated base unit (unit 1). The cable
connected to the Cascade Down connector of the base unit terminates in the Cascade Up
connector on the next unit in the stack, which is located below the base unit. This next unit is
designated unit 2. The stack is wired downward through the units and the system continues

Installation November 2010 59

Installing the Avaya Ethernet Routing Switch

to number in this manner throughout the stack. In this configuration, the base unit discovers
the stack in a cascade down (stack down) direction. The following illustration demonstrates a
typical cascade down (stack down) configuration.

Important:

Because many network management software packages assume a cascade down (stack

Cascade up

In a cascade up (stack up) configuration, the base unit is physically the top unit in the stack.
The cable connected to the Cascade Down connector of the base unit terminates in the
Cascade Up connector physically at the bottom of the stack. This next unit is designated unit

2. The stack is wired upward through the units and the system continues to number in this

Important:

Because many network management software packages use a cascade down (stack down)
configuration, Avaya recommends that you use a cascade down configuration. See Cascade

down on page 59.

The following guidelines apply for stack configuration:

• When you apply power to the stack, the base unit initializes, typically within 60 seconds,
and the entire stack powers up as a single logical unit.

• You can attach an RS-232 communications cable to the console port of any switch in the
stack to establish a console connection.

Installation November 2010 61

Installing the Avaya Ethernet Routing Switch

• You can perform a software upgrade on the stack from any switch using a Telnet session,
the Web-based Management Interface, or any SNMP-based management software.

• You can manage the stack using a Telnet session, Web-based Management Interface, or
any SNMP-based management software through any stack switch port.

• When you stack two or more switches, use the 3-foot cascade max-return cable

Caution:

If you are not installing a module in the slot, be sure to keep the metal cover plate in place over the slot.
Removing the cover plate impedes airflow and proper cooling of the unit.

Important:

Achtung:

Wenn Sie kein Modul im Schacht verwenden, muß die Metallabdeckung über dem Schacht montiert
sein. Eine Entfernung der Abdeckung führt zu einer Verschlechterung der Luftzirkulation und damit zu
einer nicht ausreichenden Kühlung der Einheit.

Important:

Si vous n'installez pas le module dans une baie, veillez à laisser la plaque métallique sur la baie. Si
vous la retirez, l'aération du module ne peut pas s'effectuer correctement.

Important:

Precaution:

Si no instala ningún módulo en la ranura, asegúrese de mantener la placa de la cubierta de metal en
la misma. Si la retira, impedirá que el aire circule y la unidad se refrigere adecuadamente.

Important:

Attenzione:

Se nello slot non vengono installati moduli, assicurarsi di mantenere la piastra di copertura metallica in
sede sopra lo slot. La rimozione della piastra impedisce la ventilazione e il corretto raffreddamento
dell'unità.

Important:

Avviso:

L'unico modo per disattivare questo dispositivo consiste nello scollegare il cavo di alimentazione.
Collegare sempre il cavo di alimentazione ad una presa che sia facilmente e rapidamente accessibile in
caso di emergenza.

Danger:

Use only power cords that have a grounding path. Without a proper ground, a person who touches the
switch is in danger of receiving an electrical shock. Lack of a grounding path to the switch can result in
excessive emissions.

Important:

Vorsicht:

Verwenden Sie nur Netzkabel mit Schutzerdung. Ohne ordnungsgemäße Schutzerdung besteht für
Personen, die den Switch berühren, die Gefahr eines elektrischen Schlages. Eine nichtvorhandene
Schutzerdung kann zu sehr starken Abstrahlungen führen.

Danger:

N'utilisez que des cordons d'alimentation équipés de trajet de mise à la terre. Sans mise à la terre
adaptée, vous risquez de recevoir une décharge électrique en touchant le commutateur. Par ailleurs,
l'absence de trajet de mise à la terre peut générer des émissions excessives.

Important:

Peligro:

Utilice únicamente cables de alimentación con toma de tierra. De lo contrario, al tocar el interruptor
puede recibir una descarga eléctrica. Si no hay un circuito de toma de tierra en el enchufe, puede
producirse un exceso de emisiones.

Important:

Pericolo:

Utilizzare esclusivamente cavi di alimentazione dotati di un percorso per la messa a terra. Senza
un'adeguata messa a terra, chiunque tocchi lo switch corre il rischio di ricevere una scossa elettrica.
L'assenza di un percorso per la messa a terra verso lo switch può comportare un eccesso di emissioni.
