·           Two vertically oriented, hot swappable fan trays at the rear. The fans draw air in from the left side and exhaust air out of the right side. For the ventilation direction inside the chassis, see "Preparing for installation."

 

NOTE: Intermixing of AC and DC power supplies is not allowed.

 

Backplane

The backplane of an S9500E switch is located inside the chassis. It provides high-speed data switching and exchanges management and control signals between MPUs and LPUs. The backplane provides the following capabilities:

·           Provides communication channels for signal exchange between cards.

·           Supports hot-swapping of cards.

·           Identifies card type.

·           Connects to the power frame, implements distributed power supply for MPUs, LPUs, switching fabric modules, fan trays and power supplies, and provides monitoring channels for MPUs to monitor power frame status.

Power supply system

The S9500E switches support both AC and DC power supply. If two power supplies are used, make sure they are the same type.

AC power supply

Each AC power supply comprises a power frame, and depending on your configuration, one or two sub power supplies installed in the power frame. The S9500E switches use the NEPS3500-A power frame and the NEPS1800-A sub power supplies.

Table 2 AC sub power supply specifications

Item	Description
Rated input voltage range	100 VAC to 120 VAC/200 VAC to 240 VAC @ 50 Hz or 60 Hz
Max input voltage range	90 VAC to 264 VAC @ 50 Hz or 60 Hz
Max input current	20 A
Max output power	1800 W @ 200 VAC to 240 VAC input 1200 W @ 100 VAC to 120 VAC input

 

NOTE: If two NEPS1800-A sub power supplies are used, the maximum output power of the NEPS3500-A power supply is 3500 W.

 

Table 3 AC power supply LED description

LED	Status	Description
Input	Steady on	Power is being correctly input.
	Off	The power supply is absent or has input voltage error.
Output	Steady on	The power supply is correctly outputting power.
	Off	The power supply has output voltage error or is absent.
Fault	Steady on	The power supply is experiencing an overvoltage, overcurrent, or over-temperature condition.
	Off	The power supply is operating properly or absent.

 

DC power supply

The S9500E switches support two DC power supply models: NEPS2000-D and NEPS3500-D.

Table 4 DC power supply specifications

Item	Description
	NEPS2000-D	NEPS3500-D
Rated input voltage range	–48 VDC to –60 VDC	–48 VDC to –60 VDC
Max input voltage range	–40 VDC to –72 VDC	–40 VDC to –72 VDC
Max input current	60 A	80 A
Max output power	2000 W	3500 W

 

NOTE: When the max input voltage of the NEPS3500-D is –40 VDC, the max output power is 3200 W.

FAIL (fault)	Steady on	The power supply is experiencing an overvoltage, overcurrent, or over-temperature condition.
	Off	The power supply is operating properly or absent.

 

Fan tray

S9500E fan trays provide the following functions:

·           Effective heat dissipation ensures long time operation of the switch.

·           Status monitoring, including fan rotation speed monitoring and fault alarming.

·           Automatic speed adjustment decreases noise and improves energy efficiency.

·           Each fan tray has two LEDs on the front panel to show its operating status.

·           The fan trays are hot swappable, and you can replace fan trays without powering off the switch.

 

IMPORTANT: The S9505E and the S9512E use the same type of fan trays. The S9508E and the S9508E-V have chassis-specific fan trays and cannot use the fan trays for any other S9500E switch models.
