The supported interface card models are:z Short-haul dual-port 10 GE CX4 interface card (LSPM1CX2P)z Dual-port 10 GE XFP interface card (LSPM1XP2P)z One-port 10 GE XFP interface card (LSPM1XP1P)Optional hotswappablepowermodules— PSR150-APSR150-DPowersupplysystemThe S5500-20TP-SI is delivered with a hot-swappable power module PSR150-A bydefault. You can install another PSR150-A or a PSR150-D for backup.The other six models of the S5500-SI series switches are designed with two fixedpower receptacles respectively. The two power inputs can be simultaneously used,acting as backup for each other. Alternatively, you can use either power input.Powersocket typesand quantity1 AC power socket and 1 RPS power socketPSR150-A: 1AC powersocketPSR150-D: 1-48V DC powersocketAC Rated voltage range: 100 VAC to 240 VAC, 50 Hz or 60 HzInput voltage range: 90 VAC to 264 VAC, 47 Hz to 63 Hz–48VDC(supportedbyPSR150-Donly)Rated voltage range: –48 VDC to –60 VDCInput voltage range: –36 VDC to –72 VDCYou can use the –48 VDC power supply in the equipment room directly or one of thefollowing two external RPS power supply units recommended by H3C to providepower supply.RPS500-A3 (–50 VDC/7.5 A, cable suite-0404A03V) or RPS1000-A3 (–54 VDC/8 A,cable suite-0404A054) for the PSR150-D power module installed on anS5500-20TP-SI.Use the external RPS power supply units recommended by H3Conly.InputvoltageRPS The rated voltage range: 10.8VDC to 13.2 VDC.Adopts RPS500-A3 using its 12VDC/10.5 A output and the cablesuite of 0404A03C.The rated voltage range: –55VDC to –52 VDC.Adopts RPS1000-A3 using its–54 VDC/25 A output and thecable suite of 0404A053.—
