Brocade Communications Systems NetIron MLXe Series, Hardware Installation Manual

Page: 89 / 305

CAUTION
Ensure that the device does not overload the power circuits, wiring, and over-current protection. To determine the
possibility of overloading the supply circuits, add the ampere (amp) ratings of all devices installed on the same circuit as the
device. Compare this total with the rating limit for the circuit. The maximum ampere ratings are usually printed on the
devices near the input power connectors.
CAUTION
All devices with DC power supplies are intended for installation in restricted access areas only. A restricted access area is
where access can be gained only by service personnel through the use of a special tool, lock and key, or other means of
security, and is controlled by the authority responsible for the location.
CAUTION
All devices with AC power sources are intended for installation in restricted access areas only. A restricted access area is a
location where access can be gained only by service personnel through the use of a special tool, lock and key, or other
means of security.
CAUTION
For the DC input circuit to the system of Brocade MLXe Series-4, Brocade MLXe Series-8, and Brocade MLXe Series-16
routers (1800W supply), make sure there is a 60 amp circuit breaker, minimum -48VDC, double pole, on the input lugs to
the power supply. The input wiring for connection to the product should be copper wire, 6 AWG, marked VW-1, and rated
minimum 90° C.
CAUTION
For the DC input circuit to the system of Brocade MLXe Series-4, Brocade MLXe Series-8, and Brocade MLXe Series-16
routers (1200W supply), make sure there is a 40 amp circuit breaker, minimum -48VDC, double pole, on the input lugs to
the power supply. The input wiring for connection to the product should be copper wire, 6 AWG, marked VW-1, and rated
minimum 90° C.
CAUTION
For the DC input circuit to the system of a Brocade MLXe Series-32 (3000W supply) make sure there is a 80 amp circuit
breaker, minimum -48Vdc, double pole, on the input lugs to the power supply. The input wiring for connection to the
product should be Listed copper wire, 2 AWG, marked VW-1, and rated minimum 90° C.
For the NEBS-compliant installation of Brocade MLXe Series-4, Brocade MLXe Series-8, and Brocade MLXe Series-16 routers with a
DC system:
CAUTION
For a DC system, use a grounding wire of at least 6 American Wire Gauge (AWG). The 6 AWG wire should be attached to an
agency-approved crimp connector crimped with the proper tool. The crimp connector should allow for securement to both
ground screws on the enclosure. For the Ground lug, use UL listed Panduit crimp connector, P/N LCD6-10A, and two
10-32, PPH, screws to secure crimp connector to chassis. Grounding position is located on the side of the chassis
adjacent ground symbol.
For the NEBS-compliant installation of Brocade MLXe Series-4, Brocade MLXe Series-8, and Brocade MLXe Series-16 routers with an
AC system:
CAUTION
For a Brocade AC system, use a ground wire of at least 6 American Wire Gauge (AWG). The ground wire should have an
agency-approved crimped connector (provided with the chassis) attached to one end, with the other end attached to
building ground. The connector must be crimped with the proper tool, allowing it to be connected to both ground screws on
the enclosure.
