Upgrading from a Previous Switch
Overview
This chapter describes how to upgrade to a CGESM from the following switches:
ProLiant BL p-Class GbE2 Interconnect Switch
ProLiant BL p-Class GbE Interconnect Switch
ProLiant BL p-Class RJ-45 Patch Panel 2
ProLiant BL p-Class RJ-45 Patch Panel
Upgrading from an Existing Switch or Patch Panel
CAUTION: Removing a switch from a powered enclosure will result in the loss of network
communications between the server blade network ports that are connected through this
switch and the segment of network infrastructure those ports need to communicate.
For continued blade server network communication and services availability, do the following
before you remove the switch. Redirect critical high-availability services or applications to use
the redundant network ports available on those blade servers that are connected through the
redundant switch in the enclosure.
IMPORTANT: If you are replacing an existing CGESM, or upgrading from a GbE2 Interconnect Switch,
a GbE Interconnect Switch, an RJ-45 Patch Panel 2, or an RJ-45 Patch Panel, and you have strict
security requirements:
Do not cable the switch until after configuration.
Or
Connect the switch to the optional Diagnostic Station. The Diagnostic Station enables you to power
up, configure, and diagnose a ProLiant p-Class server blade or a switch outside of the rack
environment.
NOTE: By default, the CGESM has port fast enabled for the downlink ports and STP enabled for the
uplink ports. During an upgrade, there will be a short STP convergence delay due to the topology
change.
