MX2008 DC Power System

 

MX2008 Seven-Feed DC Power Distribution Module Description

Note

The MX2008, MX2010, and MX2020 routers support the same power modules AC, DC, 240 V China, and universal PSMs and PDM.

In the DC power configuration, the router contains up to two DC PDMs located at the rear of the chassis in slots PDM0/Input0 and PDM1/Input1 (bottom to top). A minimum of one PDM is required per system (two PDMs per MX2008 chassis) for nonredundant power. The DC PDMs provides power interface to nine PSMs.

Four PDMs provide full redundancy.

Note

Power backplane distributes regulated 52 VDC to all boards supplied by that system.

Each DC PDM has seven DC inputs (–48 VDC and return terminals for each input) (see Figure 1). Select 60 A or 80 A input feed capacity on the DC PDM by setting the switch to the rated amperage of DC power input feeds.

Note

This switch applies to all inputs of this PDM. Selecting 60 A reduces the available power output capacity of the PSMs supplied by this PDM.

Figure 1: DC Power Distribution Module

Module
Note

The type of feed that you use on the DC PDM (60 A or 80 A) depends on the distribution scheme and distribution equipment. With a 60-A feed, the maximum power supply output power is limited to 2100 W while the maximum power supply input power is limited to 2400 W. With an 80-A feed, the maximum power supply output is limited to 2500 W while maximum power supply input power is limited to 2800 W. The system power management software calculates the available and used power based on DIP switch positions in the PDM.

Note

The MX2008, MX2010, and MX2020 routers support the same power modules AC, DC, 240 V China, and universal PSMs and PDMs.

In the DC power configuration, the router contains up to two DC power distribution modules (PDMs) located at the rear of the chassis in slots PDM0/Input0 and PDM1/Input1 (bottom to top). A minimum of one PDM is required per system (two PDMs per chassis) for nonredundant power. The DC PDM provides a power interface to nine power supply modules (PSMs).

Two PDMs provide full redundancy. In a redundant configuration, a total of fourteen 60-A or 80-A input feeds (7-feed DC PDMs), and a total of eighteen 60-A or 80-A input feeds (9-feed DC PDMs) are supported.

Note

The power backplane for a subsystem distributes regulated 52 VDC to all boards supplied by that subsystem.

Each DC PDM has seven or nine DC inputs (–48 VDC and return terminals for each input). You can select 60-A or 80-A input feed capacity on the DC PDM by setting the DIP switch on the PDM to the rated amperage of the DC power input feeds.

Note

The selected input capacity applies to all inputs of this PDM. Selecting 60 A reduces the available power output capacity of the PSMs supplied by this PDM.

MX2008 DC Power Supply Module (-48 V) Description

Note

The MX2008, MX2010, and MX2020 routers support the same power modules AC, DC, 240 V China, and universal PSMs and PDMs.

The MX2008 supports a DC power system. The DC power system operates with feeds of 60 A or 80 A current limited. A total of nine feeds are required to fully power the MX2008. Another nine feeds are required to provide feed redundancy (a total of 18 60-A or 80-A feeds). In the DC power configuration, the router contains up to nine DC PSMs located at the rear of the chassis in slots PSM0 through PSM8, (left to right). The DC PSMs in slots PSM0 through PSM8 provide power to the all router components including MPCs in slot 0 through 9, RCBs in slot 0 and 1, SFBs in slot 0 through 7, and fan trays 0 and 1.

Note

The MX2008 systems configured for DC input power must use only DC PDMs and DC PSMs. You cannot mix AC and DC PSMs or PDMs within a single system.

Up to nine PSMs may be connected in parallel to increase available system power across MPCs as needed and provide redundancy. Figure 7 shows the DC PSM.

Figure 7: DC (-48 V) Power Supply Module
DC (-48 V) Power Supply
Module

The DC power system is feed redundant. Each DC PSM can be connected to two separate feeds from different sources that are used to provide feed redundancy. If two feeds are connected, PSM input power is drawn from the feed with the higher voltage present. There are two PDMs per power system capable of carrying nine feeds each. Connect feeds from one source to one PDM and feeds from the other source to the second PDM of the power system. The primary input of the PSM is a dual redundant feed, INP0 and INP1. Both feeds are active during operation, but both feeds might or might not be providing current. Move the input mode DIP switch to the on or off position to determine the power supply feeds (see Table 3 and Figure 8). In addition, a PSM failure triggers the alarm LED on the craft interface. Each PDM has an LED per feed indicating whether the feed is active or not, or whether the feed is connected properly, see MX2008 DC Power (-48 V) System Electrical Specifications.

MX2008 DC Power Requirements

Note

The MX2008, MX2010, and MX2020 routers support the same power modules AC, DC, 240 V China, and universal PSMs and PDMs.

Table 6 lists the FRU power requirements for SFBs, RCBs, MPCs, and MICs. In addition, Table 6 lists the MPC power requirements with MICs and optics at various operating temperatures.

Typical power represents power under certain temperatures and normal operating conditions.

For PDMs with 60 A feeds, we recommend that you select the 60 A  @ –48 VDC switch for each input.

For PDMs with 80 A feeds, we recommend that you select the 80 A @ –48 VDC switch for each input.

Note

The 240 V China DC PDMs do not have a switch selection.

If you do not plan to provision as recommended above, you can use the information in Table 6 to calculate the power consumption for your hardware configuration.

Note

Unlike all the other MPCs, MPC6E, MPC8E, and MPC9E does not require an adapter card (ADC) to house the MPC in the MX2008 router.

MX2008 DC Power Distribution Description (-48 V)

Most sites distribute DC power through a main conduit that leads to frame-mounting DC power distribution panels, one of which might be located at a location near the rack that houses the router. A pair of cables (one input and one return) connects each set of PDM input terminal studs to the power distribution panel.

The PSMs can be connected to two separate feeds from different sources that are used for feed redundancy. There are two PDMs located in slots PDM0/Input0 and PDM1/Input1 that are capable of carrying seven to nine feeds each. Each feed is connected from one source to one PDM and feeds from the other source to the second PDM of the DC power system. This configuration balances power draw for the system by using the commonly deployed A/B feed redundancy.

Each system provides N+1 PSM redundancy along with N+N feed redundancy. If both DC feeds are available, operating power draws from the feed with higher voltage. These feeds are set by the input mode DIP switch located on the DC PSM (see MX2008 DC Power Supply Module (-48 V) Description). Each set of power cables powers a single DC PSM and is capable of delivering 2500 W of power if 80-A feeds are connected. If feeds that connect to one PDM fail in a redundant configuration, the other feed starts to provide full power.

Figure 11 shows a typical DC source cabling arrangement.

Figure 11: Typical DC Source Cabling to the Router
Typical DC Source Cabling
to the Router

All DC PSMs in a subsystem share the load. If one PSM fails in a redundant configuration, the remaining PSMs provide power to FRUs. Up to nine PSMs might be required to supply power to a fully configured router. A portion of power from each zone is reserved to power critical FRUs. These FRUs allow the system to operate even if power to a complete zone fails.

Caution

You must ensure that power connections maintain the proper polarity. The power source cables might be labeled (+) and (-) to indicate their polarity. There is no standard color coding for DC power cables. The color coding used by the external DC power source at your site determines the color coding for the leads on the power cables that attach to the terminal studs on each PDM.

Warning

For field-wiring connections, use copper conductors only.

Caution

Power cords and cables must not block access to device components or drape where people could trip on them.

Each set of power cables powers a single DC PSM and is capable of delivering 2500 W of power if 20 A 240 V source is connected. If feeds that connect to one PDM fail in a redundant configuration, the other feed starts to provide full power.

There is no standard color coding for DC power cables. The color coding used by the external DC power source at your site determines the color coding for the leads on the power cables that attach to the terminal studs on each PDM.

Caution

The two input sources must have similar grounding type because the PSM can see 480 V if one source has positive ground (-240 V), and the other source has negative ground (+240 V). This might damage the PSM.

Warning

For field-wiring connections, use copper conductors only.

Caution

Power cords and cables must not block access to device components or drape where people could trip on them.

DC Power (-48 V) Circuit Breaker Requirements for the MX2008 Router

Note

The MX2008, MX2010, and MX2020 routers support the same power modules AC, DC, 240 V China, and universal PSMs and PDMs.

For PDMs, if you plan to operate a maximally configured DC-powered router, we recommend that you provision at least 80 A  @ –48 VDC (nominal) for each DC input to the system. Use a customer-site circuit breaker rated according to respective National Electrical Code and customer site internal standards to maintain proper level of protection for the current specified above.

If you plan to operate a DC-powered router at less than the maximum configuration, we recommend that you provision a circuit breaker according to respective National Electrical Code and customer-site internal standards to maintain proper level of protection for the current specified above.

For PDMs, If you plan to operate a minimally configured DC-powered router, we recommend that you provision at least 60 A  @ –48 VDC (nominal) for each input to the system. Use a customer-site circuit breaker rated according to National Electrical Code and customer site internal standards to maintain proper level of protection for the current specified above.

If you plan to operate a DC-powered router at less than the maximum configuration, we recommend that you provision a circuit breaker according to respective National Electrical Code and customer-site internal standards to maintain proper level of protection for the current specified above or each DC power supply rated for at least 125% of the continuous current that the system draws at –48 VDC.

DC Power (240 V China) Circuit Breaker Requirements for the MX2000 Router

For PDMs, if you plan to operate a maximally configured DC-powered router, we recommend that you provision at least 20 A  @ 240 VDC (nominal) for each DC input to the system. Use a customer site 2 pole circuit breaker rated according to respective National Electrical Code and customer site internal standards to maintain proper level of protection for the current specified above.

If you plan to operate a DC-powered router at less than the maximum configuration, we recommend that you provision a 2 pole circuit breaker according to respective National Electrical Code and customer site internal standards to maintain proper level of protection for the current specified above or each DC power supply rated for at least 125% of the continuous current that the system draws at 240 VDC.

DC Power Cable Specifications for the MX2008 Router

Note

The MX2008, MX2010, and MX2020 routers support the same power modules AC, DC, 240 V China, and universal PSMs and PDMs.

The cable lugs attach to the terminal studs of each PDM (see Figure 13 and Figure 14).

Note

The MX2008 supports 4-AWG DC power cable lugs for 80-A input, and 6-AWG DC power cable lugs for 60-A input.

Caution

Before router installation begins, a licensed electrician must attach a cable lug to the grounding and power cables that you supply. A cable with an incorrectly attached lug can damage the router.

Caution

The router is a pluggable type A equipment installed in restricted access location. It has a separate protective earthing terminal (Metric [–M6] and English [–¼-20] screw ground lugs) provided on the chassis in addition to the grounding pin of the power supply cord. This separate protective earth terminal must be permanently connected to earth.

Table 11 summarizes the specifications for the DC power cables, which you must supply.

Table 11: DC Power Cable Specifications

Cable Type

Quantity and Specification

Power

Eighteen pairs of 4-AWG (21.2 mm2), used with 80-A PDM. Minimum 90°C wire, or as required by the local code.

Eighteen pairs of 6-AWG (13.3 mm2), used with 80-A PDM. Minimum 90°C wire, or as required by the local code.

Caution

You must ensure that power connections maintain the proper polarity. The power source cables might be labeled (+) and (–) to indicate their polarity. There is no standard color coding for DC power cables. The color coding used by the external DC power source at your site determines the color coding for the leads on the power cables that attach to the terminal studs on each PDM.
