Install the Subracks and PSU in an Equipment Rack
Rack-Mount the Subracks (-48Vdc WCS-2, WCS-4)
When installing ERA Subracks adhere to the rules listed below:
Figure 11 on Page 53 shows two configurations for mounting -48Vdc WCS and e-POI Subracks in an
equipment rack.
Figure 11. -48Vdc WCS Subrack Installation Requirements
As with any piece of IT equipment, placing the ERA system connection behind a secure firewall is highly
recommended.
Support rails are always required for -48Vdc WCS-2 and WCS-4 Subracks and e-POI Subracks.
Support rails must not block airflow.
To maximize airflow through the WCS and e-POI chassis, blank panels must be installed in all empty slots.
If additional blank panels are required, contact your local CommScope sales representative to order the
appropriate panel:
• Blank Panel Universal (PN 7688866-xx)
• Blank Panel SUI (PN 7688868-xx)
• Blank Panel AUT (PN 7688867-xx)
• e-POI Blank Module (PN 7673474-xx)
• Power Supply Filler Panel (PN 7694140-xx).
