Section 1 — Introduction
Materials Supplied
This product includes:
Equipment Required
TRX-PSFRM-TER-1RU installations:
• 1.75 in. (1 RU) rack space in Trinix or adjacent rack
• AC power outlets, 1200 W each (matching the number of TRX-PSU-
1200W power supplies installed in chassis)
For DV-33512 ONLY:
• TRX-PS-33500 chassis with ORing diodes installed.
Note Early versions of the TRX-PS33500 chassis did not include ORing diodes for
the redundant DC inputs. The installation of this back-up power supply
requires the TRX-PS-33500 chassis with the ORing diodes. To verify that
your TRX-PS-33500 chassis has the required ORing diodes, see
Figure 2 and
compare to your TRX-PS33500. The ORing diodes can be viewed through the
rear panel grill work of the TRX-33500 chassis. The diode covers about 1
square inches and is clearly visible from the rear. Contact Grass Valley if your
power supply does not have the ORing diode installed.
