Install the Subracks and PSU in an Equipment Rack
Rack-Mount the Subracks and PSU (WCS-2, WCS-4)
When installing ERA Subracks and PSUs, adhere to the rules listed below and as shown in Figure 7 on page 50 :
The PSU must be installed above the WCS Subrack to support its weight and to ensure that the DC terminals
on the rear of the unit do not come into contact with another subrack or other metal surface. There must be
1 RU of air space above the subrack.
Figure 7 on page 50 shows two configurations for mounting Subracks and PSUs in an equipment rack.
As with any piece of IT equipment, placing the ERA system connection behind a secure firewall is highly
recommended.
There must be 1 RU of air space above the PSU.
Support rails are always required for WCS-2 and WCS-4 Subracks and e-POI Subracks. Support rails should
never be used for PSU subracks to prevent contact with the DC power terminals on the rear of the units.
Support rails must not block airflow.
Disconnect all input to the PSU before adding it to or removing it from an equipment rack. If you are
removing the PSU from an equipment rack, unlatch any installed 12 Vdc or 57 Vdc Rectifier Modules from
the PSU chassis before you disconnect the DC Power and Rectifier Control cables on the rear of the
chassis.
Connect the PSU to a high leakage current ground (earth) before making any other connections to the
PSU.
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).
