Product Orientation

Note: The user can perform local and telnet configuration through this port. The console port supports asynchronous mode, 8 data bits, 1 stop bit, no parity bit. The default baud rate is 115200 bps.

Note: The USB port supports data transmission only. It does not supply power.

Status LEDs

The front panel of the DS2000 has 48 SFP28 and 8 QSFP28 port indicator LEDs. These LEDs are described in the following tables.

Table 1. Port Indicator LEDs of QSFP28
LED State	Meaning
1st LED: Green/Amber
Green on	Port link operating at max port speed
Green blinking	Port activity operating at max port speed
Amber on	Port link operating at lower speed
Amber blinking	Port activity operating at lower speed
Off	Port link down
All four LEDs are used when 4x25G or 4x10G mode is running on QSFP28 port
Green on	4x25G link on QSFP28 port
Green blinking	4x25G activity on QSFP28 port
Amber on	4x10G link on QSFP28 port
Amber on	4x10G activity on QSFP28 port
Off	Port link down

Table 2. Port Indicator LEDs of SFP28
LED State	Meaning
One Port Link/ Activity status Green/Amber bi-colored LED is provided for each front panel port
Green on	Port link operating at max port speed
Green blinking	Port activity operating at max port speed
Amber on	Port link operating at lower speed
Amber blinking	Port activity operating at lower speed
Off	Port link down

After powering on, all the port LEDs will self-check (all colors blink in sequence), and then turn green.

After Software Development Kit (SDK)/Network Operating System (NOS) runs, each port's LEDs will function as listed in the following table:

Alarm	ALM	Green On	No alarm
		Amber On	Critical alarm
		Amber 1Hz blinking	Minor alarm
		Amber 4Hz blinking	Major alarm
System	STAT	Green / Amber - Alternate blinking	Normal operation
System	STAT	Off	No power to system

Table 4. Rear Panel Status LEDs
Indicator LED	Rear Panel Sign	LED State	Meaning
Fan module	FAN1 / FAN2 / FAN3 / FAN4	Green	All fans operating normally
		Amber	Fan(s) operating abnormally
		Off	Fan absent
PSU module	P-1 / P-2	Green	All PSUs operating normally
		Red	PSU error(s) detected
		Off	PSU is off

Table 5. Management Port Indicator LEDs
Indicator LED	Status	Description
ETHERNET Port (left)	Green blinking	Port transmits data
ETHERNET Port (left)	Off	Port does not transmit data

Power Supply Unit (PSU)

The DS2000 switch contains two 550W PSUs with the support of two airflow options: front-to-back (F2B) and back-to-front (B2F).

Each PSU's maximum output power is 550W with an input voltage of 90VAC~264VAC and an output voltage of 12 VDC +/- 5%. The PSU includes a fan and a handle at the back of the power supply to support hot plug pull-out and insertion.

CAUTION: Different airflow power modules can not be mix used.

Fan Module

DS2000 switch contains four fan modules in the standard configuration. The rotation speed of the fan adjusts and adapts to the system temperature. It provides two airflow options: front-to-back (F2B) and back-to-front (B2F).
