Upgrading the Switch Software
Upgrading the Switch Software
The software upgrade procedure is described in the Cisco Configuration Assistant online help. To
upgrade the switch, you must download and use Cisco Configuration Assistant.
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.
These are the device manager limitations:
•CSCei30778
When a PC is connected directly to a switch port, the username password dialog appears twice
before the device manager appears.
The workaround is to enter the username and the password in both dialogs.
•CSCsd48669
The PC must have a network interface card (NIC) driver that supports IEEE 802.1Q packet tagging
if either:
–
The PC is directly connected to a Catalyst Express 520 switch port that is configured with the Switch
port role
–
The PC is connected to a switch that is connected through an access port to a Catalyst
Express 520 switch port that is configured with the Switch port role.
•CSCsh93742
You cannot configure the copper interface of the dual-purpose port if an SFP module is installed in
it.
The workaround is to first remove the SFP module and then to connect the copper cable.
•CSCsi40050
You cannot set up the switch for the first time if the switch is connected to an upstream DHCP server
and to your management station at the same time. (You can set up the switch by using a PC
connected to one of the switch Ethernet ports or by connecting the switch to a DHCP server, but not
both.)
The workaround is to disconnect the switch from the uplink DHCP server, connect a PC to one of
the switch Ethernet ports, and configure the switch by using the Express Setup program.
•CSCsi70143
A port fails under these conditions:
–
The port speed is configured at either 10Mb/s or 100Mb/s (instead of auto), and it is connected
to another port that also has the speed configured as 10Mb/s or 100Mb/s.
–
The ports are connected by a straight-through cable.
The workaround is to use a crossover cable to connect the two ports, regardless of the speed settings.

Important Notes
•CSCsj52489
When you start the device manager from a Firefox browser session, an invalid certificate error
appears.
The workaround is to delete the certificate(s) in Firefox and then close and restart the browser.
Follow these steps to delete the certificate(s):
–
In Firefox version 1.5, select Tools > Options > Advanced > Security > View Certificates >
Web Sites. Select the certificate(s), and click Delete to delete the certificate(s).
–
In Firefox version 2.0, select Tools > Options > Advanced > Encryption > View
Certificates > Web Sites. Select the certificate(s), and click Delete to delete the certificate(s).
When you start the device manager from Internet Explorer 7.0, a certificate error page appears.
The workaround is to click the Continue to this website (not recommended) link and continue to start
the device manager.
Important Notes
When you start the device manager in secured mode from Internet Explorer 6.0 or from FireFox1.5,
several security certificates appear. Accept all of the certificates. The device manager then appears.
For a complete list of supported browsers and operating systems, see the User Guide for the Catalyst
Express 520 Switches.
Open Caveats
This section describes the open caveats with possible unexpected activity in this software release. Unless
otherwise noted, these severity 3 Cisco IOS configuration caveats apply to all of the Catalyst Express
switches:
•CSCsj60518 (Catalyst 520-24LC, 520-24PC, and 520-24TT switches)
The port configuration is lost if you press the Admin button repeatedly when the switch is entering
and exiting direct managed mode.
The workaround is to not repeatedly press the Admin button when entering and exiting direct
managed mode. Wait at least five seconds before each press of the Admin button.
•CSCsj77293
You might not be able to complete the switch initial setup if you interrupt the process by either
disconnecting your PC from the switch or by changing your PC IP address settings.
The workaround is to restart the entire initial setup procedure, as described in the switch user guide.
•CSCsk22971
If you end your browser session without saving changes to the setup parameters during initial setup
or in direct managed mode, and then open a new browser session, the Express Setup window or the
device manager page might not appear in the new browser session.
The workaround is to type in any URL (for example, www.cisco.com). The browser then displays
the Express Setup window or the device manager.
