Juniper SRX 5800, Hardware Manual

Page: 56 / 536

WARNING: The AC power cord for the services gateway is intended for use with the
services gateway only and not for any other use.
WARNING: To meet safety and electromagnetic interference (EMI) requirements and
to ensure proper operation, you must properly ground the services gateway chassis
before connecting power. See “Grounding the SRX5800 Services Gateway” on page 239
for instructions.
CAUTION: Power cords and cables must not block access to services gateway
components or drape where people could trip on them.
NOTE: In North America, AC power cords must not exceed 4.5 m (approximately 14.75 ft) in
length, to comply with National Electrical Code (NEC) Sections 400-8 (NFPA 75, 5-2.2) and
210-52, and Canadian Electrical Code (CEC) Section 4-010(3). The cords listed in
Table 19 on page 56 are in compliance.
AC Power Circuit Breaker Requirements for the SRX5800 Services Gateway
Each AC power supply has a single AC appliance inlet located in the chassis directly above the power
supply that requires a dedicated AC power feed. We recommend that you use a dedicated customer site
circuit breaker rated for 15 A (250 VAC) minimum for each AC power supply, or as required by local code.
SRX5800 Services Gateway Standard-Capacity DC Power Supply
In the DC power configuration, the services gateway contains either two or four DC power supplies (see
Figure 19 on page 58 ), located at the lower rear of the chassis in slots PEM0 through PEM3 (left to right).
You can upgrade your DC power system from two to four power supplies.
Four power supplies provide full redundancy. If a DC power supply fails, its redundant power supply takes
over without interruption.
