Upgrading The Switch Software; Limitations And Restrictions - Cisco Catalyst Express 520-24LC Release Note

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.

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.
