Linking More Than Two Enclosures
Linking an Epica DGX 144 enclosure to multiple other types of enclosures (other than linking in a daisy
chain off an enclosure with a 10Base-2 / BNC connector) requires a Multi-Port Switch and RJ-45
straight-through patch cables. Depending on the other types of enclosures, a Media converter(s) and
RG-58 coax cable(s) may also be required. FIG. 12 below shows an Epica DGX 144 enclosure linked to
an Optima and to a Modula using a 5-Port Switch and a Media Converter.
Important: If the system has an RJ-45 connector labeled TCP/IP, do not use it for linking
enclosures. Do not use an RJ-45 enclosure linking connector for a TCP/IP connection.
Cable Length Requirements
Note: If you have questions regarding cabling or network related issues in conjunction with using a
Multi-Port Switch (or hub) for linking enclosures, contact your network administrator.
When attaching multiple enclosures to a Multi-Port Switch, one or more can be connected directly to
the Multi-Port Switch (see steps below) and/or one or more can use a Media Converter to connect to
the Multi-Port Switch (see steps on page 29). In a system with multiple 10Base-2 enclosures, only one
needs to be attached to the Multi-Port Switch with a Media Converter. The rest can be daisy-chained.
To link an Epica DGX 144 enclosure to a Multi-Port Switch:
1.
Insert one end of the RJ-45 straight-through patch cable into the Enc Link (RJ-45) Ethernet port on
the Epica DGX 144 enclosure.
2.
Insert the other end of the RJ-45 straight-through patch cable into the Multi-Port Switch.
3.
Repeat Steps 1 and 2 for enclosures with 10Base-T ports.* For 10Base-2 ports, go to page 29.
* Applies when linking an Optima, Optima SD, Precis SD, or Epica DGX 16/32 to a Multi-Port Switch .
Important: Attach 50-ohm termination connectors to the open ends of the T-connectors on the
Media Converter and on the last enclosure on the cable run.
