Virtual Chassis

EX4100-H switches have dedicated Virtual Chassis ports (VCPs) that you can use to interconnect member switches of a Virtual Chassis (VC). EX4100-H switches can interoperate with EX4100 and EX4100-H switches in a VC. You can interconnect a maximum of 10 switches to form a VC. There are two ways to form VC on EX4100-H switches - HiGig Mode and HiGig over Ethernet (HGoE) Mode. Refer Understanding HiGig and HGoE Modes in a Virtual Chassis.

HGoE is the default VC mode for all EX4100-H switches. To form VC between EX4100-H and EX4100 and/or EX4100-F switches, VC mode needs to be changed to HiGig on EX4100-H or HGoE on EX4100 and/or EX4100-F. In HiGig mode, you can operate the interconnected switches as a single device, and use all the Virtual Chassis ports as Virtual Chassis ports or use all of them as network ports. You cannot mix multiple types of ports within a single, logical device. But in HGoE mode, mixed-mode is supported - some ports can be Virtual Chassis ports and some ports can be network ports.

On EX4100-H switches, Virtual Chassis is supported only Virtual Chassis ports and uplink ports and not on access ports.

Note:

On EX4100-H-12MP switches, the two 10G SFP+ dedicated virtual chassis ports on PIC 1 support both methods - HiGig and HGoE (but one at a time). Whereas, the two 10G SFP+ uplink ports on PIC 2 support only HGoE method.

Note:

When VC is in HiGiG mode uplink ports will not function.

For more information about Virtual Chassis, see Understanding EX Series Virtual Chassis.

Dry Contact Alarm

EX4100-H-12MP has a dry contact connector on the front panel for dry-contact alarms support. The alarm input contact ports can be used to generate LED alarms on the switch and the alarm output contact ports can be used to connect to external devices.

Table 2: Components of the Dry Contact Alarm

LEDs	Alarm input ports	Alarm relay ports
IN0 – LED for IN0 alarm input IN1 – LED for IN1 alarm input OUT – LED for alarm relay ports (NO, COM, NC)	GND – Grounding port to connect grounding wire IN0 – Alarm input IN1 – Alarm input	NO - Normally open alarm relay port COM - Common alarm relay port NC - Normally closed alarm relay port

Alarm input ports

Alarm input ports are dry contact input ports to connect to security sensors such as door or window monitors. When the alarm input ports receive a signal, the alarm input is sensed and reported to the management software to take further action. If the alarm input signal exceeds the threshold value, the LEDs (IN0, IN1) for the alarm inputs glow to indicate an alarm condition. There are two input alarm input ports. You can configure up to two input alarm ports (0, 1) to operate and trigger an alarm condition. Remember to mandatorily connect wire to the GND port when configuring an input alarm port or ports.

CAUTION:

alarm input signal threshold is 5v.

Alarm relay ports

The relay on the switch has three alarm relay ports, NO, COM, and NC. Alarm relay ports provide dry contacts to connect to external equipment, such as an audible or visual alarm that switches on or off, for example, a bell or a light. You can configure the alarm relay ports to trigger/activate based on an alarm condition in an input alarm port or a chassis alarm. An alarm condition is indicated by the LED (OUT). The alarm relay ports operate on the principles of a relay.

• NO (Normally open alarm relay port): No electric voltage in normal condition. Under abnormal condition, this port will have electric voltage; the COM will attach to it forming a circuit.

• COM (Common alarm relay port): Attached to the NC port in normal condition. Under abnormal condition, this port will attach to the NO port.

• NC (Normally closed alarm relay port): Electric voltage present in normal condition. Under abnormal condition, this port will not have electric voltage because the COM port will detach from it.

Configuring chassis alarm relays

The following is an example configuration of chassis relay alarms involving a VC with two EX4100-H-12MP switches.

• In line 1, on FPC 0 of the VC, the alarm input port (IN0) is set to trigger a major alarm (red) if input signal is detected that exceeds the threshold.

• In line 2, on FPC 0 of the VC, the alarm input port (IN1) is set to trigger a minor alarm (yellow) if input signal is detected that exceeds the threshold.

• In line 3, on FPC 1 of the VC, the alarm input port (IN0) is set to trigger a major alarm (red) if input signal is detected that exceeds the threshold.

• In line 4, on FPC 1 of the VC, if a major alarm is triggered by the alarm input port (IN0) of FPC1, then trigger the first alarm relay port (NO - Normally open alarm relay port).

After setting this configuration, assume you have connected the NO alarm relay port to a buzzer. When an alarm is triggered, the buzzer produces a sound. The OUT LED indicates this alarm in the continuously glowing red pattern. This is one of the use-cases of a dry contact alarm. Another use case is when IN1 of FPC 0 senses an alarm signal. Because IN1 of FPC 0 is set to trigger a minor alarm, this alarm condition is indicated by the IN1 LED in the continuously glowing red color pattern. You can issue show chassis alarms to view this alarm on the CLI.

Note:

• You can configure the alarm relay to detect alarm conditions under normally open or normally closed configuration – but not both.

• You cannot start using the alarm inputs and alarm relay outputs without initial configuration. Issue the show chassis craft-interface command to view the alarm inputs and alarm relay outputs’ statuses. If not configured, configure the alarm inputs and alarm relay outputs – see relay

• Issue show chassis alarms to view all alarms including any alarms generated by the alarm inputs and/or alarm relay outputs.

• Use show chassis in edit mode to check the configured dry contact alarms.

• When configurations are applied for dry contact alarm ports, it takes around 10 to 15 seconds for dry contact alarm LEDs to change their states. Refer Dry Contact Alarm LEDs.

Power over Ethernet Ports

EX4100-H switches are available with Power over Ethernet Plus (PoE+/PoE++) capability. The switch models provide perpetual and fast PoE functionality. PoE, PoE+, and PoE++ ports provide electrical power to devices—such as IP phones, wireless access points, and security cameras—through network cables. Because the network cables provide electrical current, you do not need separate power cords for those devices.

1. The EX4100-H-12MP switch models support PoE++ (90 W) by default.

For more information about PoE support on EX series switches, see Understanding PoE on EX Series Switches.

Note:

IEEE 802.3bt class 4 powered devices require category 5 or higher Ethernet cables.

EX4100-H Power System

EX4100-H-12MP supports a mix of AC and DC PSUs. The following are the EX4100-H switch models with their compatible power systems:

• EX4100-H-12MP uses the external 340W AC and/or 340W DC PSU.
