Figure 22 Connecting a power cord for the built-in power module on an S5130-28PS-EI
switch (2)
Connecting a DC power cord for the built-in DC power
module (other switch models than S5130-28PS-EI)
CAUTION:
•
No DC power cord is provided with the switch that has a built-in DC power module. To use a –48
VDC power source for power supply, purchase an H3C recommended DC power cord yourself.
To use an RPS for power supply, purchase a power cord compatible with the RPS yourself.
•
The DC-input power receptacle on the S5130-52S-EI or S5130-52TP-EI switch requires a DC
power cord with a JD5-A connector.
•
The DC-input power receptacle on the S5130-28S-HPWR-EI, S5130-28TP-PWR-EI,
S5130-52S-PWR-EI, or S5130-52TP-PWR-EI switch requires a DC power cord with a JD5
connector.
•
To connect a DC power cord to a –48 VDC power source, identify the positive (+) and negative (-)
marks on the two wires of the power cord to avoid connection mistakes.
To connect a DC power cord for the built-in DC power module on other switch models than
S5130-28PS-EI:
1.
Correctly orient the power cord connector and insert the connector into the DC-input power
receptacle on the switch. See callout 1 in
Figure 23 .
The DC-input power receptacle and the power cord connector have disorientation rejection
designs. If you cannot insert the connector into the receptacle, re-orient the connector rather
than use excessive force to push it in.
2.
Use a flat-blade screwdriver to fasten the screws on the connector to secure the connector to
the DC-input receptacle. See callout 2 in
Figure 23 .
3.
Connect the other end of the power cord to a –48 VDC power source or an RPS.
