16 Installing the Nortel Ethernet Routing Switch
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. These electrostatic
voltages can result from friction including, but not exclusive to, pulling
cabling through conduits, walking across carpeted areas, and building
static charge in clothing. ESD damage occurs when you improperly handle
electronic components 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 but not others, or to some pins before others, which can
potentially damage the networking equipment.
To protect the Nortel Ethernet Routing Switch against ESD damage, take
the following preventive measures before you connect any data cables to
the device:
•
Always use anti-static 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, Nortel 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.

Environmental requirements
17
To install the ESD discharge cable, perform the following procedure.
Step
Action
1
Connect the ground lug on the ESD discharge cable to a safe and
suitable earth ground.
2
Briefly connect all RJ-45 cable connectors to the female RJ-45
connector of the ESD discharge cable, 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.

provides a secondary power source for Nortel Ethernet Routing Switch
4500 Series devices. In addition, when connected to a Power over Ethernet
(PoE) switch, such as the 4548GT-PWR or the 4550T-PWR, the RPS 15
can supplement the amount of Direct to Ethernet (DTE) power to deliver up
to 740 watts of PoE.
Nortel DC to DC converter module
To use the Nortel Ethernet Routing Switch Redundant Power Supply Model
15 (RPS 15) with the Nortel Ethernet Routing Switch 4500 Series non-PoE
models, 4548GT, 4550T, and 4526FX requires a DC-DC converter module.
The DC–DC converter module plugs into the slot on the back of a non-PoE
switch and connects the RPS to the switch.
For information about connecting the converter module to the Nortel
Ethernet Routing Switch 4500 Series non-PoE models, 4548GT, 4550T, or
4526FX, see DC-DC Converter Module for the Baystack 5000 Series Switch
(215081-A).

Nortel Ethernet Routing Switch 4500 series stacking
The Nortel 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. The stack is
managed as a single unit.
Stack connector
The stack connector is a component of the Nortel 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 &quot;Stack connector&quot; (page 44) diagram.
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 is also displayed on the front panel
LED display (see &quot;Switch LED state indicators&quot; (page 36)).

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 &quot;Simplified
stacking diagram&quot; (page 45)&quot;Connecting cascade cables&quot; (page 46)).
Note: To create a stack connection, order the appropriate Nortel
Ethernet Routing Switch 4500 Series cascade cables to ensure fail-safe
stacking. A 1.5 foot stacking cable is included with the switch. For
stacking three or more units (maximum 8 units per stack), order the 5’,
10’, 14’ or 16.4’ 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 &quot;Simplified
stacking diagram&quot; (page 45) and &quot;Connecting cascade cables&quot; (page 46).
&quot;Simplified stacking diagram&quot; (page 45) illustrates a simple, two-switch
stack connection.

to Unit 2 Cascade Up connector)
3. Cascade Cable (connected from Unit 2 Cascade Down connector to
Base Unit Cascade Up Connector)
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, and so on, 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, a stack MAC address is
automatically assigned during stack initialization. The stack MAC address is
the base unit MAC address plus 1. If another unit in the stack is assigned

Nortel Ethernet Routing Switch 4500 series stacking
47
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.
Note: 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.
Redundant cascade stacking
The Nortel Ethernet Routing Switch 4500 Series allows a stack of up to
eight units into a dual-path 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.
&quot;Redundant cascade stacking&quot; (page 48) shows a typical example of a stack
configuration reacting to a failed connection in the stack configuration.

In the example, the following occur:
•
Unit 3 becomes non-operational 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.
Note: Automatic Unit Replacment (AUR) for both configuration and
software is enabled for all Nortel 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 to

replacement of a failed unit occurs, any port-specific configuration is
restored .
Step
Action
1
Remove the failed switch from the stack.
2
Obtain a like-for-like replacement switch.
3
With the new unit powered 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 may
automatically reboot 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.
—End—
If the base unit is being replaced, 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 non-base units.
Removing 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
Stacking 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. Nortel recommends
that you use Cascade Down configuration. (see &quot;Cascade down&quot; (page 50)

Cascade down
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 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.

2. Last Unit
3. Cascade Cable

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

52 Installing the Nortel Ethernet Routing Switch
Regardless of stack configuration, the following guidelines apply:
•
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.
•
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 (AL4518002-E6) to complete the link from the last
unit in the stack to the base unit.

dem Schacht montiert sein. Eine Entfernung der Abdeckung f&uuml;hrt zu einer
Verschlechterung der Luftzirkulation und damit zu einer nicht ausreichenden
K&uuml;hlung der Einheit.
ATTENTION
Si vous n’installez pas le module dans une baie, veillez &agrave; laisser la plaque
m&eacute;tallique sur la baie. Si vous la retirez, l’a&eacute;ration du module ne peut pas
s’effectuer correctement.
ATTENTION
Precaution:
Si no instala ning&uacute;n m&oacute;dulo en la ranura, aseg&uacute;rese de mantener la placa de la
cubierta de metal en la misma. Si la retira, impedir&aacute; que el aire circule y la unidad
se refrigere adecuadamente.
ATTENTION
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’unit&agrave;.

ATTENTION
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.
ATTENTION
Vorsicht:
Verwenden Sie nur Netzkabel mit Schutzerdung. Ohne ordnungsgem&auml;&szlig;e
Schutzerdung besteht f&uuml;r Personen, die den Switch ber&uuml;hren, die Gefahr eines
elektrischen Schlages. Eine nichtvorhandene Schutzerdung kann zu sehr starken
Abstrahlungen f&uuml;hren.
DANGER
N’utilisez que des cordons d’alimentation &eacute;quip&eacute;s de trajet de
mise &agrave; la terre. Sans mise &agrave; la terre adapt&eacute;e, vous risquez de
recevoir une d&eacute;charge &eacute;lectrique en touchant le commutateur.
Par ailleurs, l’absence de trajet de mise &agrave; la terre peut g&eacute;n&eacute;rer
des &eacute;missions excessives.
ATTENTION
Peligro:
Utilice &uacute;nicamente cables de alimentaci&oacute;n con toma de tierra. De lo contrario, al
tocar el interruptor puede recibir una descarga el&eacute;ctrica. Si no hay un circuito de
toma de tierra en el enchufe, puede producirse un exceso de emisiones.
ATTENTION
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 pu&ograve; comportare un eccesso di emissioni.
