iPlex Installation and Hardware Specification Guide
The power sources must be correctly grounded and the power connections must
comply with the specifications listed in the following table.
Power Setup Requirements
Grounding the
Chassis
.
To ground the chassis, do the following:
1
On the front of the right rack rail, scrape off the paint around a pair of rail
holes to allow electrical contact for the ground lug, as shown in Figure that
follows.
2
Prepare a length of 12 green AWG stranded copper cable, rated at a minimum
of 10 Amps with a maximum length of 5 feet (1.5 meters).
3
Crimp the ring terminal provided in the chassis install kit to one end of the
cable.
4
Apply a thin layer of an anti-oxidant electrical paste such as “NoOx” to the
lug and the ground connector.
5
Insert the cable into the green terminal with the ground symbol. Tighten the
screw.
6
Attach the ground connector to the scraped hole on the rack rail according to
local practice as shown in Figure that follows.
Power The iPlex has a maximum power dissipation of 300 Watts.
The total power required per system depends on the number
of packs installed and the services delivered. Power specifi-
cations are provided in this manual.
Voltage - Minimum operating: -40 VDC
- Nominal operating: -48 VDC
- Maximum operating: - 60 VDC
Maximum
Current Input
10 Amps
Ground The grounding scheme is a common bonding network
(CBN) as defined by GR-1089-core Issue 4, Section 9.3.1.
• Each chassis must be grounded through the equipment
rack to a building/enclosure ground in accordance with
NEC and local practices.
• A minimum 12 AWG green stranded copper wire suitable
for 10 Amps with a maximum length of 5 feet (1.53 m) is
recommended.
Protection ISAMP UL Listed circuit breaker is recommended.
WARNING: DANGER!
A frame ground is required for secondary voltage protection; follow
local grounding practices to ensure a good frame ground connection
to the iPlex. Improper grounding may result in an electrical hazard.
