Better Than Standard UPS systemsBetter Than Standard UPS systems
• Longer battery life– unique charging scheme
• DC power output– instead of ac
– better for communications applications
• UPS can be unreliable
• No specialized wiring required
All at about the same price

BPS12 and the MXBPS12 and the MX
• Provides battery backup for MX systems
• Provides PoE for MX1200
• No software installation required
• MX will shut down gracefully– when dc voltage drops to a certain level

Reliability and LongevityReliability and Longevity
• High quality lead acid batteries
• Sophisticated charging scheme
• BPS12 disconnects outputs – if equipment continues to draw power when the
batteries are discharged
– prolongs battery life
• Fans activate only when required
• 3 year warranty standard

Simple to InstallSimple to Install
• Front, mid, or rear mount in a 19" rack
• Uses standard ac power in the network room– no specialized wiring
• Inhibit switch on the BPS12– allows outputs to be disconnected
– safely connect to your network devices

BPS12 ConcatenationBPS12 Concatenation
• Concatenate multiple BPS12 systems– to obtain longer backup time
• Two systems provide 24 Ah– maximum current remains unchanged

BPS12 Status and AlarmBPS12 Status and Alarm
• 3 LEDs– Power shows charging or discharging
– Load indicates the overall power draw on the system.
– Status shows multiple conditions• such as when the inhibit switch is active
• Buzzer provides – audible alarm to indicate critical events

Why you should not use a UPS, 1Why you should not use a UPS, 1
• UPS provides ac output– not appropriate for telecommunications equipment– unnecessary complexity
• MX250 can detect 48 V is discharged– automatically shuts down safely– not possible with a UPS
• Comparable UPS requires 30 A @ 110 Vac– maybe costly install– BPS uses standard ac outlet
• BPS12 can be concatenated for longer backup– not possible with UPS

• Comparable UPS weighs twice BPS12– difficult to transport and install
• BPS12 has three year warranty– comparable UPS has one year or two year warranty
Standard UPS is heavyLook how easy it is with the BPS12

BPS12 SummaryBPS12 Summary
• Reliable and industrial unit– compatible with any device requiring –48 Vdc
• Simple to install
• Essential part of communications system– maintains phone operation during ac outage
– should be sold with every MX system
