4. Insert the new fan tray, and push it firmly all the way to ensure contact at

11.2 Replacing an EFN324
The procedure to be followed for replacing an EFN324 depends on whether
the Ethernet access switch is a stand­alone node or an embedded node. A
stand­alone node is controlled directly by PEM. An embedded node is a node
controlled by an ECN. Replacing a stand­alone EFN324 is described in section
11.2.1 on page 82. Replacing an embedded EFN324 is described in section
11.2.2 on page 83.
11.2.1 Replacing a Stand­alone EFN324
PEM only accepts the replacement of EFN324 if the EFN324 is replaced with
exactly the same type of EFN324. For example, a stand­alone EFN324f cannot
be replaced by an EFN324df.
Stand­alone EFN324 Ethernet access switches are managed by PEM. The
EFN324 configuration data is stored in the PEM database, and so making a
back up of the configuration file before the replacement is not necessary.
To replace a stand­alone EFN324 with an EFN324 of the same type, do the
following:
1. Remove the power supply from the old EFN324.
2. Remove the EFN324 from the network.
3. Configure the new EFN324 using the same IP address, netmask, default
gateway, management VLAN and (optionally) multicast VLANs as the old
EFN324. The initial configuration for a stand­alone EFN324 is described in
detail in the
EFN324 Installation Guide .
