Figure 28-4 Connecting Cisco High-Density Extension Modules (EVM-HD-8FXS/DID) to a Main
Distribution Frame or Patch Panel
Distribution panels are generally available from multiple cable and network adapter vendors. Customers
may, at their sole discretion, consider using a patch panel from Black Box Corporation (JPM2194A—see
Figure 28-5
).
(Mention of products or services other than Cisco products or services is for information
purposes only and constitutes neither an endorsement nor a recommendation.)
The Black Box patch
panel accommodates RJ-11 and RJ-45 combinations possible on Cisco high-density expansion modules,
and offers flexibility for expansion module upgrades (either analog or digital). For ordering information,
see the Cisco High-Density Extension Module data sheet.
