Cluster Compatibility

You cannot create and manage switch clusters through the device manager. To create and manage switch clusters, use the command-line interface (CLI) or the Network Assistant application.

When creating a switch cluster or adding a switch to a cluster, follow these guidelines:

When you create a switch cluster, we recommend configuring the highest-end switch in your cluster as the command switch.

If you are managing the cluster through Network Assistant, the switch with the latest software should be the command switch.

The standby command switch must be the same type as the command switch. For example, if the command switch is a Cisco IE 3000 switch, all standby command switches must be Cisco IE 3000 switches.

For additional information about clustering, see Getting Started with Cisco Network Assistant and Release Notes for Cisco Network Assistant (not orderable but available on Cisco.com), the software configuration guide, and the command reference.

CNA Compatibility

Cisco IOS 12.2(44)EX and later is only compatible with Cisco Network Assistant (CNA) 5.4 and later. You can download Cisco Network Assistant from this URL:

http://www.cisco.com/pcgi-bin/tablebuild.pl/NetworkAssistant

For more information about Cisco Network Assistant, see the Release Notes for Cisco Network Assistant on Cisco.com.

Upgrading the Switch Software

These are the procedures for downloading software. Before downloading software, read this section for important information:

Archiving Software Images

Upgrading a Switch by Using the Device Manager or Network Assistant

Upgrading a Switch by Using the CLI

Recovering from a Software Failure

Finding the Software Version and Feature Set

The Cisco IOS image is stored as a bin file in a directory that is named with the Cisco IOS release. A subdirectory contains the files needed for web management. The image is stored on the compact flash memory card.

You can use the show version privileged EXEC command to see the software version that is running on your switch. The second line of the display shows the version.

You can also use the dir filesystem: privileged EXEC command to see the directory names of other software images that you might have stored in flash memory.

Deciding Which Files to Use

The upgrade procedures in these release notes describe how to perform the upgrade by using a combined tar file. This file contains the Cisco IOS image file and the files needed for the embedded device manager. You must use the combined tar file to upgrade the switch through the device manager. To upgrade the switch through the command-line interface (CLI), use the tar file and the archive download-sw privileged EXEC command.

Table 5 lists the filenames for this software release.

Table 5 Cisco IOS Software Image Files 

Filename

Description

ies-lanbase-tar.122-44.EX1.tar

Catalyst IE 3000 image file and device manager files.
This image has Layer 2+ features.

ies-lanbasek9-tar.122-44.EX1.tar

Catalyst IE 3000 cryptographic image file and device manager files. This image has the Kerberos and SSH features.


Archiving Software Images

Before upgrading your switch software, make sure that you have archived copies of the current Cisco IOS release and the Cisco IOS release to which you are upgrading. You should keep these archived images until you have upgraded all devices in the network to the new Cisco IOS image and until you have verified that the new Cisco IOS image works properly in your network.

Cisco routinely removes old Cisco IOS versions from Cisco.com. See Product Bulletin 2863 for more information:

http://www.cisco.com/en/US/products/sw/iosswrel/ps5187/prod_bulletin0900aecd80281c0e.html

You can copy the bin software image file on the flash memory to the appropriate TFTP directory on a host by using the copy flash: tftp: privileged EXEC command.


Note Although you can copy any file on the flash memory to the TFTP server, it is time consuming to copy all of the HTML files in the tar file. We recommend that you download the tar file from Cisco.com and archive it on an internal host in your network.


You can also configure the switch as a TFTP server to copy files from one switch to another without using an external TFTP server by using the tftp-server global configuration command. For more information about the tftp-server command, see the "Basic File Transfer Services Commands" section of the Cisco IOS Configuration Fundamentals Command Reference, Release 12.2 at this URL:

http://www.cisco.com/en/US/products/sw/iosswrel/ps1835/products_command_reference_chapter09186a00800ca744.html

Upgrading a Switch by Using the Device Manager or Network Assistant

You can upgrade switch software by using the device manager or Network Assistant. For detailed instructions, click Help.


Note When using the device manager to upgrade your switch, do not use or close your browser session after the upgrade process begins. Wait until after the upgrade process completes.


Upgrading a Switch by Using the CLI

This procedure is for copying the combined tar file to the switch. You copy the file to the switch from a TFTP server and extract the files. You can download an image file and replace or keep the current image.


Note Make sure that the compact flash card is inserted into the switch before downloading the software.


To download software, follow these steps:


Step 1 Use Table 5 to identify the file that you want to download.

Step 2 Download the software image file. If you have a SmartNet support contract, go to this URL, and log in to download the appropriate files:

http://www.cisco.com/kobayashi/sw-center/sw-lan.shtml

To download the image for a Cisco IE 3000 switch, click Cisco IE 3000 software. To obtain authorization and to download the cryptographic software files, click Cisco IE 3000 3DES Cryptographic Software.

Step 3 Copy the image to the appropriate TFTP directory on the workstation, and make sure that the TFTP server is properly configured.

For more information, see the Cisco IE 3000 Switch Software Configuration Guide.

Step 4 Log into the switch through the console port or a Telnet session.

Step 5 (Optional) Ensure that you have IP connectivity to the TFTP server by entering this privileged EXEC command:

Switch# ping tftp-server-address

For more information about assigning an IP address and default gateway to the switch, see the software configuration guide for this release.

Step 6 Download the image file from the TFTP server to the switch. If you are installing the same version of software that is currently on the switch, overwrite the current image by entering this privileged EXEC command:

Switch# archive download-sw /overwrite /reload 
tftp:[[//location]/directory]/image-name.tar

The /overwrite option overwrites the software image in flash memory with the downloaded one.

The /reload option reloads the system after downloading the image unless the configuration has been changed and not saved.

For //location, specify the IP address of the TFTP server.

For /directory/image-name.tar, specify the directory (optional) and the image to download. Directory and image names are case sensitive.

This example shows how to download an image from a TFTP server at 198.30.20.19 and to overwrite the image on the switch:

Switch# archive download-sw /overwrite tftp://198.30.20.19/ies-lanbase-tar.122-44.EX.tar

You can also download the image file from the TFTP server to the switch and keep the current image by replacing the /overwrite option with the /leave-old-sw option.


Recovering from a Software Failure

For additional recovery procedures, see the "Troubleshooting" chapter in the software configuration guide for this release.

Installation Notes

You can assign IP information to your switch by using these methods:

The Express Setup program, as described in the switch getting started guide.

The CLI-based setup program, as described in the switch hardware installation guide.

The DHCP-based autoconfiguration, as described in the switch software configuration guide.

Manually assigning an IP address, as described in the switch software configuration guide.

Limitations and Restrictions

You should review this section before you begin working with the switch. These are known limitations that will not be fixed, and there is not always a workaround. Some features might not work as documented, and some features could be affected by recent changes to the switch hardware or software.

This section contains these limitations:

Cisco IOS Limitations

Device Manager Limitations

Cisco IOS Limitations

These limitations apply to the Cisco IE 3000 switches:

Configuration

Ethernet

IP

Multicasting

QoS

SPAN and RSPAN

Trunking

VLAN

Configuration

These are the configuration limitations:

A static IP address might be removed when the previously acquired DHCP IP address lease expires.

This problem occurs under these conditions:

When the switch is booted up without a configuration (no config.text file in flash memory).

When the switch is connected to a DHCP server that is configured to give an address to it (the dynamic IP address is assigned to VLAN 1).

When an IP address is configured on VLAN 1 before the dynamic address lease assigned to VLAN 1 expires.

The workaround is to reconfigure the static IP address. (CSCea71176 and CSCdz11708)

When connected to some third-party devices that send early preambles, a switch port operating at 100 Mb/s full duplex or 100 Mb/s half duplex might bounce the line protocol up and down. The problem is observed only when the switch is receiving frames.

The workaround is to configure the port for 10 Mb/s and half duplex or to connect a hub or a nonaffected device to the switch. (CSCed39091)

When port security is enabled on an interface in restricted mode and the switchport block unicast interface command has been entered on that interface, MAC addresses are incorrectly forwarded when they should be blocked

The workaround is to enter the no switchport block unicast interface configuration command on that specific interface. (CSCee93822)

A traceback error occurs if a crypto key is generated after an SSL client session.

There is no workaround. This is a cosmetic error and does not affect the functionality of the switch. (CSCef59331)

When the logging event-spanning-tree interface configuration command is configured and logging to the console is enabled, a topology change might generate a large number of logging messages, causing high CPU utilization. CPU utilization can increase with the number of spanning-tree instances and the number of interfaces configured with the logging event-spanning-tree interface configuration command. This condition adversely affects how the switch operates and could cause problems such as STP convergence delay.

High CPU utilization can also occur with other conditions, such as when debug messages are logged at a high rate to the console.

Use one of these workarounds:

Disable logging to the console.

Rate-limit logging messages to the console.

Remove the logging event spanning-tree interface configuration command from the interfaces. (CSCsg91027)

The far-end fault optional facility is not supported on the GLC-GE-100FX SFP module.

The workaround is to configure aggressive UDLD. (CSCsh70244).

Ethernet

These is the Ethernet limitation:

Traffic on EtherChannel ports is not perfectly load-balanced. Egress traffic on EtherChannel ports are distributed to member ports on load balance configuration and traffic characteristics like MAC or IP address. More than one traffic stream may map to same member ports based on hashing results calculated by the ASIC.

If this happens, uneven traffic distribution will happen on EtherChannel ports.

Changing the load balance distribution method or changing the number of ports in the EtherChannel can resolve this problem. Use any of these workarounds to improve EtherChannel load balancing:

for random source-ip and dest-ip traffic, configure load balance method as src-dst-ip

for incrementing source-ip traffic, configure load balance method as src-ip

for incrementing dest-ip traffic, configure load balance method as dst-ip

Configure the number of ports in the EtherChannel so that the number is equal to a power of 2 (i.e. 2, 4, or 8)

For example, with load balance configured as dst-ip with 150 distinct incrementing destination IP addresses, and the number of ports in the EtherChannel set to either 2, 4, or 8, load distribution is optimal.(CSCeh81991)

IP

This is the IP limitation:

When the rate of received DHCP requests exceeds 2,000 packets per minute for a long time, the response time might be slow when you are using the console. The workaround is to use rate limiting on DHCP traffic to prevent a denial of service attack from occurring. (CSCeb59166)

Multicasting

These are the multicasting limitations:

If the number of multicast routes and Internet Group Management Protocol (IGMP) groups are more than the maximum number specified by the show sdm prefer global configuration command, the traffic received on unknown groups is flooded in the received VLAN even though the show ip igmp snooping multicast-table privileged EXEC command output shows otherwise. The workaround is to reduce the number of multicast routes and IGMP snooping groups to less than the maximum supported value. (CSCdy09008)

IGMP filtering is applied to packets that are forwarded through hardware. It is not applied to packets that are forwarded through software. Hence, with multicast routing enabled, the first few packets are sent from a port even when IGMP filtering is set to deny those groups on that port. There is no workaround. (CSCdy82818)

If an IG MP report packet has two multicast group records, the switch removes or adds interfaces depending on the order of the records in the packet:

If the ALLOW_NEW_SOURCE record is before the BLOCK_OLD_SOURCE record, the switch removes the port from the group.

If the BLOCK_OLD_SOURCE record is before the ALLOW_NEW_SOURCE record, the switch adds the port to the group.

There is no workaround. (CSCec20128)

When IGMP snooping is disabled and you enter the switchport block multicast interface configuration command, IP multicast traffic is not blocked.

The switchport block multicast interface configuration command is only applicable to non-IP multicast traffic.

There is no workaround. (CSCee16865)

Incomplete multicast traffic can be seen under either of these conditions:

You disable IP multicast routing or re-enable it globally on an interface.

A switch mroute table temporarily runs out of resources and recovers later.

The workaround is to enter the clear ip mroute privileged EXEC command on the interface. (CSCef42436)

After you configure a switch to join a multicast group by entering the ip igmp join-group group-address interface configuration command, the switch does not receive join packets from the client, and the switch port connected to the client is removed from the IGMP snooping forwarding table.

Use one of these workarounds:

Cancel membership in the multicast group by using the no ip igmp join-group group-address interface configuration command on an SVI.

Disable IGMP snooping on the VLAN interface by using the no ip igmp snooping vlan vlan-id global configuration command. (CSCeh90425)

Entering the shutdown and the no shutdown interface configuration commands on the internal link can disrupt the PoE operation. If a new IP phone is added while the internal link is in shutdown state, the IP phone does not get inline power if the internal link is brought up within 5 minutes.

The workaround is to enter the shutdown and the no shutdown interface configuration commands on the Fast Ethernet interface of a new IP phone that is attached to the service module port after the internal link is brought up. (CSCeh45465)

QoS

These are the quality of service (QoS) limitations:

Some switch queues are disabled if the buffer size or threshold level is set too low with the mls qos queue-set output global configuration command. The ratio of buffer size to threshold level should be greater than 10 to avoid disabling the queue. The workaround is to choose compatible buffer sizes and threshold levels. (CSCea76893)

When auto-QoS is enabled on the switch, priority queuing is not enabled. Instead, the switch uses shaped round robin (SRR) as the queuing mechanism. The auto-QoS feature is designed on each platform based on the feature set and hardware limitations, and the queuing mechanism supported on each platform might be different. There is no workaround. (CSCee22591)

SPAN and RSPAN

These are the SPAN and Remote SPAN (RSPAN) limitations.

Cisco Discovery Protocol (CDP), VLAN Trunking Protocol (VTP), and Port Aggregation Protocol (PAgP) packets received from a SPAN source are not sent to the destination interfaces of a local SPAN session. The workaround is to use the monitor session session_number destination {interface interface-id encapsulation replicate} global configuration command for local SPAN. (CSCed24036)

Trunking

These are the trunking limitations:

The switch treats frames received with mixed encapsulation (IEEE 802.1Q and Inter-Switch Link [ISL]) as frames with FCS errors, increments the error counters, and the port LED blinks amber. This happens when an ISL-unaware device receives an ISL-encapsulated packet and forwards the frame to an IEEE 802.1Q trunk interface. There is no workaround. (CSCdz33708)

IP traffic with IP options set is sometimes leaked on a trunk port. For example, a trunk port is a member of an IP multicast group in VLAN X but is not a member in VLAN Y. If VLAN Y is the output interface for the multicast route entry assigned to the multicast group and an interface in VLAN Y belongs to the same multicast group, the IP-option traffic received on an input VLAN interface other than one in VLAN Y is sent on the trunk port in VLAN Y because the trunk port is forwarding in VLAN Y, even though the port has no group membership in VLAN Y. There is no workaround. (CSCdz42909).

For trunk ports or access ports configured with IEEE 802.1Q tagging, inconsistent statistics might appear in the show interfaces counters privileged EXEC command output. Valid IEEE 802.1Q frames of 64 to 66 bytes are correctly forwarded even though the port LED blinks amber, and the frames are not counted on the interface statistics. There is no workaround. (CSCec35100).

VLAN

These are the VLAN limitations:

If the number of VLANs times the number of trunk ports exceeds the recommended limit of 13,000, the switch can fail.

The workaround is to reduce the number of VLANs or trunks. (CSCeb31087)

When line rate traffic is passing through a dynamic port, and you enter the switchport access vlan dynamic interface configuration command for a range of ports, the VLANs might not be assigned correctly. One or more VLANs with a null ID appears in the MAC address table instead.

The workaround is to enter the switchport access vlan dynamic interface configuration command separately on each port. (CSCsi26392)

Device Manager Limitations

This is the device manager limitation:

When you are prompted to accept the security certificate and you click No, you only see a blank screen, and the device manager does not launch.

The workaround is to click Yes when you are prompted to accept the certificate. (CSCef45718)

Important Notes

This section describe the important notes related to this software release for the Cisco IE 3000 switches.

Device Manager Notes

These notes apply to the device manager:

You cannot create and manage switch clusters through the device manager. To create and manage switch clusters, use the CLI or Cisco Network Assistant.

We recommend this browser setting to speed up the time needed to display the device manager from Microsoft Internet Explorer.

From Microsoft Internet Explorer:

1. Choose Tools > Internet Options.

2. Click Settings in the "Temporary Internet files" area.

3. From the Settings window, choose Automatically.

4. Click OK.

5. Click OK to exit the Internet Options window.

The HTTP server interface must be enabled to display the device manager. By default, the HTTP server is enabled on the switch. Use the show running-config privileged EXEC command to see if the HTTP server is enabled or disabled.

Beginning in privileged EXEC mode, follow these steps to configure the HTTP server interface:

 
Command
Purpose

Step 1 

configure terminal

Enter global configuration mode.

Step 2 

ip http authentication {aaa | enable | local}

Configure the HTTP server interface for the type of authentication that you want to use.

aaa—Enable the authentication, authorization, and accounting feature. You must enter the aaa new-model interface configuration command for the aaa keyword to appear.

enable—Enable password, which is the default method of HTTP server user authentication, is used.

local—Local user database, as defined on the Cisco router or access server, is used.

Step 3 

end

Return to privileged EXEC mode.

Step 4 

show running-config

Verify your entries.

The device manager uses the HTTP protocol (the default is port 80) and the default method of authentication (the enable password) to communicate with the switch through any of its Ethernet ports and to allow switch management from a standard web browser.

If you change the HTTP port, you must include the new port number when you enter the IP address in the browser Location or Address field (for example, http://10.1.126.45:184 where 184 is the new HTTP port number). You should write down the port number through which you are connected. Use care when changing the switch IP information.

If you are not using the default method of authentication (the enable password), you need to configure the HTTP server interface with the method of authentication used on the switch.

Beginning in privileged EXEC mode, follow these steps to configure the HTTP server interface:

 
Command
Purpose

Step 1 

configure terminal

Enter global configuration mode.

Step 2 

ip http authentication {enable | local | tacacs}

Configure the HTTP server interface for the type of authentication that you want to use.

enable—Enable password, which is the default method of HTTP server user authentication, is used.

local—Local user database, as defined on the Cisco router or access server, is used.

tacacs—TACACS server is used.

Step 3 

end

Return to privileged EXEC mode.

Step 4 

show running-config

Verify your entries.

Open Caveats

This section describes the open caveats in this software release:

CSCsc96474

The switch might display tracebacks similar to these examples when a large number of IEEE 802.1x supplicants try to repeatedly log in and log out.

Examples:

Jan 3 17:54:32 L3A3 307: Jan 3 18:04:13.459: %SM-4-BADEVENT: Event 'eapReq' is invalid for the current state 'auth_bend_idle': dot1x_auth_bend Fa9

Jan 3 17:54:32 L3A3 308: -Traceback= B37A84 18DAB0 2FF6C0 2FF260 8F2B64 8E912C Jan 3 19:06:13 L3A3 309: Jan 3 19:15:54.720: %SM-4-BADEVENT: Event 'eapReq_no_reAuthMax' is invalid for the current ate 'auth_restart': dot1x_auth Fa4

Jan 3 19:06:13 L3A3 310: -Traceback= B37A84 18DAB0 3046F4 302C80 303228 8F2B64 8E912C Jan 3 20:41:44 L3A3 315: .Jan 3 20:51:26.249: %SM-4-BADEVENT: Event 'eapSuccess' is invalid for the current state 'auth_restart': dot1x_auth Fa9

Jan 3 20:41:44 L3A3 316: -Traceback= B37A84 18DAB0 304648 302C80 303228 8F2B64 8E912C

There is no workaround.

CSCsd03580

When IEEE 802.1x is globally disabled on the switch by using the no dot1x system-auth-control global configuration command, some interface level configuration commands, including the dot1x timeout and dot1x mac-auth-bypass commands, become unavailable.

The workaround is to enable the dot1x system-auth-control global configuration command before attempting to configure interface level IEEE 802.1x parameters.

CSCsk65142

When you enter the boot host retry timeout global configuration command to specify the amount of time that the client should keep trying to download the configuration and you do not enter a timeout value, the default value is zero, which should mean that the client keeps trying indefinitely. However, the client does not keep trying to download the configuration.

The workaround is to always enter a non zero value for the timeout value when you enter the boot host retry timeout timeout-value command.

CSCsi70454

The configuration file used for the configuration replacement feature requires the character string end\n at the end of the file. The Windows Notepad text editor does not add the end\n string, and the configuration rollback does not work.

These are the workarounds. (You only need to do one of these.)

Do not use a configuration file that is stored by or edited with Windows Notepad.

Manually add the character string end\n to the end of the file.

CSCsj87991

A switch configured for Link Layer Discovery Protocol (LLDP) might not correctly report the enabled switch capabilities in the LLDP type, length, and value (TLV) attributes. System capabilities appear correctly, but the enabled capabilities are not identified if the switch is configured only as a Layer 2 switch.

There is no workaround.

CSCsj88169

When you successfully upgrade an image by using device manager and click No when prompted to reload the image, device manager becomes unusable.

The workaround is to manually reload the switch.

CSCsm95883

When an unsuccessful forward open request message is returned on the switch, the response does not contain the connection serial number, vendor ID, or vendor serial number information. Only the general and extended error codes are returned.

This problem only applies to unsuccessful forward open response messages.

The workaround is to enable the CIP debug command to determine the cause of the forward open failure.

CSCso00078

When a 100FX-FE SFP module is connected to the switch, and you change the media-type from SFP to copper, the copper link does not come up. This problem only occurs when two IE3000 switches are connected with both copper and fiber connections on the same port.

These are the workarounds:

To bring the fiber link back up, set the media-type to SFP module mode.

To bring the copper link back up, reload the switch.

CSCsq19944

When configuring a switch management VLAN to be another VLAN during Express Setup, the PC loses the network connection to the switch if it remains connected to the same port.

These are the workarounds:

Unplug the PC that was running Express Setup, and plug it into a different port.

Change the management VLAN by using the device manager.

CSCsq52244

When a diagnostic or port mirroring role is defined on an interface and you change it to another port role, the port role icon in device manager shows as Unknown.

The workaround is to configure the port role on the interface to none before you configure the other port roles.

CSCsq76774

If you remove the secure MAC address from an interface through CIP (Common Industrial Protocol), the switchport port-security violation restrict CLI configuration remains on the interface.

The workaround is to use the CLI to remove any settings remaining on the port.

CSCsr13187

The show cip object tcp/ip interface privileged EXEC command displays an old value for the domain name after it has been unconfigured with the no ip domain-name global configuration command.

The workaround is to ignore the domain name output of the show cip object tcp/ip interface privileged EXEC command.

Resolved Caveats

These are the caveats resolved in Cisco IOS Release 12.2(44)EX1:

CSCsq03277

When you disable switch ports over CIP through the output assembly, the switch no longer fails to disable switch ports.

CSCsq77659

This version of the software contains the latest version of the EDS (Electronic Data Sheet) files.

CSCsq85207

The redundant power status in the CIP switch parameter is now consistent with the output from the show facility-alarm status user EXEC command.

CSCsq92092

During the ODVA (Open DeviceNet Vendors Association) encapsulation test, the switch no longer fails at the maximum-size NOP packet test. The switch no longer replies to the UnRegister session message.

The ODVA File object test no longer fails when the file size is a multiple of the transfer buffer size. After loading the EDS file, the EDS file now correctly changes to the FileLoaded state.

CSCsq92227

The switch no longer returns a success response for a request to set an invalid interface configuration attribute value at the CIP TCP/IP interface object.

CSCsq92438

The autonegotiation status is now set in the CIP InterfaceFlag attribute of the Ethernet link object.

CSCsr05262

The CIP get and set services no longer return invalid data or cause the switch to fail for invalid Ethernet link instances. Instead, the invalid destination error is returned.

The CIP response that is returned after you set the file type attribute is now formatted correctly.

When you use the CIP set service on read-only attributes, you now receive an error response. When you set read-only attributes of the vlan and config file instances you now receive correct error code.

When a CIP file download transfer is aborted, the file object now returns to the fileEmpty state.

CSCsr23823

The CIP Ethernet link object no longer returns a blank MAC address for the physical address attribute of instance 27. Instance 27 is the switch virtual interface over which CIP traffic passes.

Grounding the Switch

Step 6: Use a ratcheting torque screwdriver to tighten the ground screw and ring terminal lug to the switch front panel to 8.5 in-lb, the maximum recommended torque.

Wiring the DC Power Source

Step 6: Use a ratcheting torque flathead screwdriver to torque the power and relay connector captive screws (above the installed wire leads) to 2 in-lb, the maximum recommended torque.

Resetting the Switch

Follow these steps to return your switch to the factory default settings. These are reasons why you might want to reset the switch:

You installed the switch in your network and cannot connect to it because you assigned the wrong IP address.

You want to clear all configurations from the switch and assign a new IP address.

You want to reset the password on the switch.


Caution Resetting the switch deletes the configuration and reboots the switch.

To reset the password on the switch:

1. Power off the switch.

2. Power on the switch, and at the same time, press and hold down the Express Setup button until all the system LEDs turn red.

3. Release the Express Setup button, and the switch continues to boot.

After the switch restarts, continue to run Express Setup.
