1.3 MULTI-HOST SYSTEMS

ADC’s FlexWave Prism provides a Multi-Host feature that allows a Prism Remote to be

shared by multiple Host Units. To accomplish this:

•• One Host is designated as the IP Manager for a set of Remotes; this Host can serve

as IP manager for multiple Remotes. As the IP Manager, the managing Host

controls the exchange of management data with the Remote(s).

•• There is no Host to Host connectivity.

•• A Prism Remote can receive bands over multiple fibers that originate on different

Hosts. However, only one Host, the IP Manager, can manage the Remote. If a Host

attempts to manage a Remote already under the management of an IP Manager,

the second Host causes an IP Conflict fault (see “Viewing Host SeRF Optical Ports”

on page 224).

•• All the Hosts in a Multi-Host network can be configured to serve as clock master.

Each Host will be configured with a priority level in the range of

. The Host

with the priority level of

distributes the clock in the network. If the Host

designated as clock master fails or shuts down, the Host with the next highest

priority level takes over. (For information on setting the master clock, see “Set the

Clock Priority Level” on page 150.)

•• The FlexWave EMS provides a

Linking Mode

parameter that can be set to

Automated

Manual

for each Host. The

Linking Mode

is applicable for all Remotes connected

to the IP Manager. A Multi-Host system requires that the

Linking Mode

be set to

Manual

(see “(Optional) Configuring Multi-Host Systems for Manual Mode” on

page 168.

•• The Host that manages the Remote must be able to provision one or more

passbands on that Remote for which the Host does not have a DART card. Remote

DARTs are linked back to one or more Hosts in a Multi-Host system.
