vaya Ethernet Routing Switch 4500 Series Power over Ethernet (PoE) switches, Avaya
Ethernet Routing Switch 4548GT-PWR, and Avaya Ethernet Routing Switch 4550T-PWR, can
use an optional 470-Watt (W) Avaya Ethernet Routing Switch RPS 15 redundant power supply.
The RPS 15 power supply chassis is two units high and can accommodate up to three RPS
modules, each supporting up to four devices, to provide redundant power and uninterrupted
operation in power failure. One RPS module connected to a PoE switch can provide up to 15.4
W for each port on all 48 ports. The RPS modules fit into the rear of the RPS 15 chassis. The
UPS and associated battery pack module fit into the front of the chassis.
The non-PoE switches, Avaya Ethernet Routing Switch 4548GT, 4550T, and 4526FX, can use
an optional 150W Avaya Ethernet Switch Power Supply Unit 10 and require the DC-DC
Converter Module. The Avaya Ethernet Switch Power Supply Unit 10 provides scalable power
redundancy and protection to low-wattage networking equipment. The PSU modules slide into
the front of the Avaya Ethernet Routing Switch RPS 15 chassis.

Auto Unit Replacement
You can use the
retaining the configuration of the unit. This feature requires the stack power to be on during
the unit replacement.
The main feature of the AUR is the ability to retain the configuration (CFG) image of a unit in
a stack during a unit replacement. The retained CFG image from the old unit is restored to the
new unit. Because retained CFG images are kept in the DRAM of the stack, the stack power
must be on during the procedure.
Important:
For Auto Unit Replacement to function properly, the new unit and the existing units in the
stack must all run the same version of software and diagnostic. In case of a two high stack,
only replacing a non-base-unit is currently supported.
You can manually restore an associated configuration (same unit number) of a unit in a stack
including base unit (if the stack is of 3 units or bigger).
Important:
If the
base unit is reset before you restore the configuration, the base unit erases the saved
configuration information for non-base units.
The following information also relates to this feature:
• The new unit must be the same hardware configuration as the old, including the same
number of ports.

Auto Unit Replacement
Important:
Restore a CFG image to a new unit happens only if you meet the following conditions.
• The AUR feature is enabled.
• At least one INACTIVE CFG mirror image exists in the stack.
• The MAC Address of the new unit is different from all the AMA of the INACTIVE CFG
mirror images in the stack.
The image restore process consists of the following steps.
Add a new unit to a stack:
a. If more than one INACTIVE CFG mirror image is in the stack, select the one
with the smallest unit ID for restoration.
b. Send the INACTIVE CFG mirror image in the stack to the new unit. The
INACTIVE CFG mirror image becomes ACTIVE.
c. The new unit saves the received CFG image to the flash drive.
d. The new unit resets itself.
For example, if you add a unit 5 (MAC Address 5) to the stack shown in Figure 4: CFG mirror
images in the stack after removing the BU (unit 1) on
page 24, the following occurs (see
Figure
5: CFG mirror images in the stack after adding unit 5 on page 26):
• The INACTIVE CFG 1 mirror image is copied to the CFG 5 image. Unit5 now has the
configuration of unit 1, which is no longer in the stack.
•
The INACTIVE CFG 1 mirror image in unit 2 becomes ACTIVE.
• The INACTIVE CFG 1 mirror image in unit 3 is removed.
• The MAC Address 5 of the unit 5 becomes the new AMA of the CFG1 mirror image.

Agent Auto Unit Replacement
Use the enhancement to the
Replacement (AAUR), to ensure that all units in a stack have the same software image by
inspecting units joining a stack and downloading the stack software image to any unit that has
a dissimilar image. AAUR is enabled by default.

1. When a stand-alone switch joins an AAUR-enabled stack, the switch software
image is inspected.
2. If the switch software image differs from the stack software image, the AAUR
functionality downloads the stack software image to the joining unit.
3. The joining unit is then reset and becomes a member of the stack upon a reboot.
The log file displays the following messages when AAUR completes successfully:

of the non-base unit with the diagnostic image saved in the base unit of a stack. You must
enable AAUR on the stack first.
Release 5.2 and up support DAUR. Previous software releases do not support DAUR.
Diagnostic AUR updates the diagnostic image on inserted units in the same way that AAUR
performs this function for agent code.
The DAUR process starts when you enable AAUR if there is a stand-alone unit with a different
diagnostic image connected to the stack. This process updates all the units in the stack.
When you enable or disable AAUR, you also enable or disable DAUR. The default for AAUR
is enabled, so DAUR is also enabled by default.
There are no commands to separately enable or disable DAUR.
The log file displays the following messages when DAUR completes successfully:
I 2 00:02:01:20 18 DAUR - Info: Receive request for diag image, start
transfer
I 2 00:02:01:22 19 DAUR - Info: Diag transfer finished
Add a unit to a stack
Unit Replacement (DAUR) enables the switch to update the diagnostic image
When you enable AAUR on stack and then add another unit with different software image, this
unit does not join the stack immediately. The unit is now in stand-alone mode.
The new unit sends an AAUR request to the up stream port. If the unit does not receive an
answer, it sends a request to the down stream port. After the image transfers successfully, the
switch reboots.
If you add a unit with the base unit select switch set to off to a unit with base unit select switch
set, the non-base unit gets the diagnostic image from the base unit.
Configuration — System April 2011 27
System configuration fundamentals
When the switch finishes the diagnostic image version update, the switch performs an AAUR
check. If the new unit has the same agent image as the stack, the unit reboots. If the new unit
has a different agent image, the switch performs an AAUR.
Note:
The new unit added on a stack must have an agent image with software release 5.1.0 or
higher or AAUR and DAUR cannot upgrade the new unit.

units breaks. The Stack Forced Mode allows you to manage one of the stand-alone devices
from a broken stack of two with the previous stack IP address.
If you enable Stack Forced Mode on a stack, you enable Stack Forced Mode on all units in the
stack. Stack Forced Mode becomes active only if the stack fails.
You can configure Stack Forced Mode through ACLI.
See
Setting Stack Forced Mode on page 109 for procedures to set the Stack Forced Mode
on a switch.
Stack Forced Mode applies to a stand-alone switch that is part of a stack of two units. When
functioning in this mode, the stand-alone switch keeps the previous stack IP settings (IP
address, netmask, gateway). That allows an administrator to reach the device through an IP
connection by telnet or EDM.
If one unit fails, the remaining unit ( base or non-base unit) keeps the previous stack IP settings.
The remaining unit issues a gratuitous ARP packet when it enters Stack Forced Mode, in order
for other devices on the network to update their ARP cache.
If the stack connection between the two units fails (a stack cable failure, for example), both
stand-alone units retain the IP settings. To detect if the other stack partner is also using the
previous stack IP settings, each device issues an ARP request on the IP address.
Mode allows one or both units to become stand-alone switches if a stack of two
When a failure occurs in a stack of 2 units when forced stack mode is enabled, the previous
non-base unit sends out a gratuitous ARP onto the management network. The purpose of
sending out this gratuitous ARP is so that the non-base unit of a failed 2 unit stack can
determine if the base unit is still operational and using the stack IP address. Such a failure
situation in which both the base unit and non-base unit were operational, but not part of a stack
could be possible if the 2 units in a stack were connected by a single stack cable and that stack
cable were then removed or failed. If the previous non-base unit receives a reply from the
previous base unit of the stack, the previous non-base unit knows that the previous base unit
is still operational and does not take over ownership of the stack IP address, but instead will
use the local switch IP address if configured. If on the other hand the previous non-base unit
does not receive a response from the previous base-unit; the previous non-base unit will now
take over ownership of the stack IP address and issue a gratuitous ARP with it's own MAC

address to ensure that all devices on the management VLAN have their ARP caches
appropriately updated.
Stack Forced Mode allows non-EAP clients connected to the device to still authenticate
themselves and maintain connectivity to the network. Non-EAP clients authenticate by the
device with RADIUS, which is based on the stack IP address. In Stack Forced Mode, the device
retains the IP settings of the stack of two.
The functional unit stays in Stack Forced Mode until either a reboot or it joins a stack.
A settlement timer prevents several stack failures that occur at an interval of a few seconds to
lead to a device entering Stack Forced Mode after it was part of a stack larger than two units.
A device enters Stack Forced Mode if and only if it was part of a stack of two for 30 seconds
or longer.
If the switch is in Stack Force mode and you want to set a switch IPv6 address, you must first
delete the active IPv6 interface and then configure the switch IPv6 address. If you use Telnet,
SSH or EDM to change the settings, the switch will lose IPv6 connectivity to the switch. Avaya
recommends that you change the settings with the Console Interface to switch or use an IPv4
address for management.
IPv6 management
This module provides information about the IPv6 management feature of the A
Routing Switch 4500 Series switch platform.
IPv6 Management allows the user to configure an IPv6 address on the management VLAN.
This enables IPv6 connectivity. The management VLAN can have both an IPv4 and an IPv6
address configured simultaneously (Avaya Ethernet Routing Switch 4500 functions as a dual
stack network node).
There is no IPv6 routing support in the current phase and therefore only one IPv6 interface is
associated to the management VLAN. You can only perform IPv6 interface configuration
(enabling, assigning IPv6 address and prefix, changing other parameters, querying interface
statistics) from ACLI or through SNMP (EDM).
IPv6 Management adds support for new standard MIBs (IP-MIB—RFC 4293, TCP-MIB—RFC
4022, UDP-MIB—RFC 4113) as well as the enterprise MIB rcIpv6.
If the switch is in Stack Force mode and you want to set a switch IPv6 address, you must first
delete the active IPv6 interface and then configure the switch IPv6 address. If you use Telnet,
SSH, or EDM to change the settings, the switch will lose IPv6 connectivity to the switch. Avaya
