Power Supply Description

The router uses either AC or DC power (see Figure 1 and Figure 2). The power supplies are

internally connected to the midplane, which distributes the different output voltages they

produce throu

ghout the system and its components.

An enable control signal on the output connector ensures that the power supply is fully

seated into t

he router midplane before the power supply can be turned on. The enable pin

prevents a user-accessible energy hazard, so there is no interlocking mechanism. The

enable pin disables the voltage at the output connector if the power supply is not turned

off before re

moval.

M7i and M10i Internet Routers Power Supply Installation Instructions 1

Power Supply Desc

ription

On an M7i router, if two power supplies are installed, they are fully redundant and share the

load during normal operation. A single power supply can provide full power for as long as

the router is o

perational. Redundancy is necessary only if one of the power supplies fails.

On an M10i router, if three AC power supplies or four DC power supplies are installed, they

are fully redu

ndant and share the load during normal operation. Two power supplies can

provide full power for as long as the router is operational. Redundancy is necessary only if

one of the power supplies fails.

Power supplies are hot-removable and hot-insertable. Each power supply has a handle to

facilitate removal from the chassis. When one power supply fails or is switched off, the

remaining po

wer supplies immediately and automatically assume the entire electrical load.

Each power supply has an LED that indicates power supply status. Table 3 describes the

LED states.

AC Grounding and Power Cord Specifications

To ground an

AC-powered router, plug each power supply into a grounded AC power

receptacle. The receptacle provides the grounding for the router, so no additional grounding

is necessary. The receptacle must be within about 8 ft (2.5 m) of the router and must be

easily acce

ssible.

Detachable AC power cords, each 2.5 m (approximately 8 ft) long, are supplied with the

router. Th

eappliancecoupleratthefemaleendofthecordinsertsintotheapplianceinleton

the faceplate of the AC power supply. The coupler is type C13 as described by International

Electrotechnical Commission (IEC) standard 60320. The plug at the male end of the power

cord fits i

nto the power source receptacle that is standard for your geographical location.

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 supplied with the router are in compliance.

Table 4 provides specifications and Figure 3 depicts the plug on the AC power cord provided

Power cords and cables must not block access to router components or

drape where people could trip on them.

DC Grounding, Connection, and Cable Specifications

To ground a DC-powered router, connect a grounding cable to earth ground and then attach it

to one of the chassis grounding points on the rear of the chassis. To supply power to the

router, connect power cables to a separate, dedicated DC power source for each power supply

and attach the cables to the field-wiring terminals on each power supply. Most sites distribute

DC power through a main conduit that leads to frame-mounted DC power distribution panels,

one of which might be located at the top of the rack that houses the router. A pair of cables

(one input and one return) connects the field-wiring terminals to the power distribution panel.

Table 5 summarizes the specifications for the grounding and power cables, which you supply.

For field-wiring connections, use copper conductors only.

Figure 12 and Figure 13 show how to attach the grounding and power cables. The grounding

cable attach

es to the grounding points on the router above the power supplies. The power

cables insert into the field-wiring terminals located on each power supply— the input

terminal is labeled -48V and the return terminal is labeled RTN.

Before rout

er installation begins, a licensed electrician must attach a cable

lug to the grounding and power cables that you supply. A cable with an

incorrectl

y attached lug can damage the router (for example, by causing

ashortcircuit).

Power cords and cables must not block access to router components or

drape whe

re people could trip on them.

Tools and Parts Required

To replace a power supply, you need the following tools and parts:

• Electrostatic bag or antistatic mat

• Electro

static discharge (ESD) grounding wrist strap
