How-To: Paragon Essentials
xvii
Case 8. Creating Multiple Paths to the Same Server(s)
Purpose: To ensure that there is redundant access to specific servers. In
this example, we will create three available paths for access to specific
servers using the structure of multiple Base Units.
Note: A Base Unit is the “first-tier” Paragon switch.
1. Prepare six Paragon switches, such as P2-UMT1664M and/or
P2-UMT832M.
2. Choose three of them as Base Units, two as the 2
nd
tier, and one as
the 3
rd
tier. If these switches do not share the same firmware version,
make sure the versions of lower tiers are later than those of upper
tiers. For example, Base Unit is with firmware version 4.2 and 2
nd
Tier
with version 4.0.
3. Connect all of these Paragon switches with Category 5 (Cat5) UTP
cables from the channel ports of lower tiers to user ports of upper
tiers as illustrated below:
