Table 5 Core Switch 2/64 Information
Core Switch 2/64 Description
Power supply
requirements
Customers reconfiguring SAN Director 2/128-only configurations by
adding Core Switch 2/64 blades must ensure that all three power supply
FRUs are installed, because Core Switch 2/64 blades have greater power
requirements.
Table 6 Fabric OS area information
Fabric OS Area Description
Compatibility Sometimes in a mixed fabric of Fabric OS 4.x, 3.x, and 2.x, fabric
reconfiguration is caused by link reset on 3.x or 2.x. This happens only in a
fabric containing Fabric OS 3.x versions released earlier than 3.1.0 or
Fabric OS 2.x versions released earlier than 2.6.1 that are under heavy
traffic or CPU-intensive operations, such as large (50 KB) zone database
propagation. Use the latest revision of code across all releases in a mixed
fabric.
Ethernet port IP
addresses
When a Core Switch 2/64 or SAN Director 2/128 fails over to its standby
CP for any reason, the IP addresses for the two logical switches move to
that CP blade’s Ethernet port. This might cause informational ARP address
reassignment messages to appear on other switches in the fabric. This is
normal behavior, because the association between the IP addresses and
the MAC addresses has changed.
Firmware download
During a firmware download, rebooting or power cycling the CPs could
corrupt the compact flash.
CAUTION: Do not attempt to power off the CP board during firmware
download, to avoid high risk of corrupting your flash.
Firmware download
Fabric OS 4.1.x, 4.2.x, and 4.4.0b non-disruptive firmware download
allows for firmware downgrades and upgrades; however, you might see
warning messages like the following:
0x239 (fabos): Switch: 0, Info PDM-NOTFOUND, 4, File
not found
(/etc/fabos/mii.0.cfg)
These warnings can be ignored.
