By default, outlets are sequentially powered on in the ascending order from outlet 1 to the final when turning ON or power cycling all outlets on the PDU. You can change the order in which the outlets power ON. This is useful when there is a specific order in which equipment should be powered up first.

In addition, you can make a delay occur between two outlets that are turned on consecutively. For example, if the power-on sequence is Outlet 1 through Outlet 8, and you want the PDU to wait for 5 seconds after turning on Outlet 3 before turning on Outlet 4, assign a delay of 5 seconds to Outlet 3.

alarmed State sensors enter the abnormal state.

The more thresholds are enabled for a sensor, the more sensor states are available for it. The "normal' state is always available regardless of whether any threshold is enabled.

For example:

• When a sensor only has the Upper Critical threshold enabled, it has two sensor states: normal and above upper

critical.

• When a sensor has both the Upper Critical and Upper Warning thresholds enabled, it has three sensor states: normal,

States of "above upper warning" and "below lower warning" are warning states to call for your attention.

States of "above upper critical" and "below lower critical" are critical states that require you to immediately handle.

Configuring An Assertion Timeout

Assertion Timeout:

The value of each enabled threshold determines the reading range of each available sensor state. For details, refer to

(on page 50).

If multiple sensor states are available for a specific sensor, the PDU asserts a state for it whenever a bad state change occurs.

To assert a state is to announce a new, "worse" state.

Below are bad state changes that cause the PDU to assert.

1. above upper warning --> above upper critical

2. normal --> above upper warning

3. normal --> below lower warning

4. below lower warning --> below lower critical

1. Click the Thresholds tab or title bar as shown.

Chapter 3: Using the Web Interface

How "Assertion Timeout" is helpful:

2. Click the desired sensor

(required), and then click Edit Thresholds.

The Edit Thresholds page appears.

3. Modify the Assertion Timeout field as desired.

In the threshold settings, the Assertion Timeout field postpones or even cancels the "assertion" action. It determines how long a sensor must be in the "worse" new state before the PDU triggers the "assertion" action. If that sensor changes its state again within the specified wait time, the PDU does NOT assert the worse state.

Note:

•

To disable the assertion timeout, set it to 0 (zero).

•

For most sensors, the measurement unit in the "Assertion Timeout" field is sample. Sensors are measured every second, so the timing of a sample is equal to a second. BCM2 is an exception to this, with a sample of 3 seconds.

4. Click Save.

If you have created an event rule that instructs the PDU to send notifications for assertion events, setting the "Assertion Timeout" is helpful for eliminating a number of notifications that you may receive in case the sensor's readings fluctuate around a certain threshold.

Assertion Timeout Example for Temperature Sensors

Assertion Timeout = 5 samples (that is, 5 seconds)

"To De-assert" and Deassertion Hysteresis

To de-assert a state:

above upper critical

above upper warning

normal

below lower warning

below lower critical

2 3 4

Chapter 3: Using the Web Interface

Assumption:

Upper Warning threshold is enabled. Upper Warning = 25 (degrees Celsius)

When a temperature sensor's reading exceeds 25 degrees Celsius, moving from the "normal" range to the "above upper warning" range, the PDU does NOT immediately announce this warning state. Instead it waits for 5 seconds, and then does either of the following:

• If the temperature remains above 25 degrees Celsius in the "above upper warning" range for 5 seconds, the PDU

performs the "assertion" action to announce the "above upper warning" state.

• If the temperature drops below 25 degrees Celsius within 5 seconds, the PDU does NOT perform the "assertion"

action.

After the PDU asserts a worse state for a sensor, it may de-assert that state later on if the readings improve.

To de-assert a state is to announce the end of the previously asserted worse state.

Below are good state changes that cause the PDU to de-assert the previous state.

1. above upper critical --> above upper warning

2. above upper warning --> normal

3. below lower warning --> normal

4. below lower critical --> below lower warning

Chapter 3: Using the Web Interface

Deassertion Hysteresis:

How "Deassertion Hysteresis" is helpful:

"Deassertion" level = 20-3 = 17 (degrees Celsius)

In the threshold settings, the Deassertion Hysteresis field determines a new level to trigger the "deassertion" action.

This function is similar to a thermostat, which instructs the air conditioner to turn on the cooling system when the temperature exceeds a pre-determined level. "Deassertion Hysteresis" instructs the PDU to de-assert the worse state for a sensor only when that sensor's reading reaches the pre-determined "deassertion" level.

For upper thresholds, this "deassertion" level is a decrease against each threshold. For lower thresholds, this level is an increase to each threshold. The absolute value of the decrease/increase is exactly the hysteresis value.

For example, if Deassertion Hysteresis = 2, then:

• Upper Critical = 33, so its "deassertion" level = 33 - 2 = 31.

• Upper Warning = 25, so its "deassertion" level = 25 - 2 = 23.

• Lower Critical = 10, so its "deassertion" level = 10 + 2 = 12.

• Lower Warning = 18, so its "deassertion" level = 18 + 2 = 20.

To use each threshold as the "deassertion" level instead of determining a new level, set the Deassertion Hysteresis to 0 (zero).

If you have created an event rule that instructs the PDU to send notifications for deassertion events, setting the "Deassertion Hysteresis" is helpful for eliminating a number of notifications that you may receive in case a sensor's readings fluctuate around a certain threshold.

Deassertion Hysteresis Example for Temperature Sensors

Upper Warning threshold is enabled. Upper Warning = 20 (degrees Celsius) Deassertion Hysteresis = 3 (degrees Celsius)

Managed vs. Unmanaged Sensors/Dry Contacts

How the Automatic Management Function Works

When the PDU detects that a temperature sensor's reading drops below 20 degrees Celsius, moving from the "above upper warning" range to the "normal" range, either of the following may occur:

• If the temperature falls between 20 and 17 degrees Celsius, the PDU does NOT perform the "deassertion" action.

• If the temperature drops to 17 degrees Celsius or lower, the PDU performs the "deassertion" action to announce the

end of the "above upper warning" state.

If there are environmental sensor packages connected to the PDU, they are listed on the Peripherals page. For more information, refer to the Premium+ PDU with RackLink Environmental Sensors User Manual at

An environmental sensor package comprises one or some of the following sensors/dry contacts:

• Numeric sensors: Detectors that show both readings and states, such as temperature sensors.

• State sensors: Detectors that show states only, such as contact closure sensors.

• Dry contacts: A dry contact controls a system or mechanism so it shows states only.

The PDU communicates with unmanaged ones. See

When the number of "managed" sensors/dry contacts has not reached the maximum, the PDU automatically brings newly detected sensors/dry contacts under management by default.

One PDU can manage a maximum of 32 sensors/dry contacts.

Note: To disable the automatic management function, see

Creating IP Access Control Rules

To configure IPv4 access control rules:

Chapter 3: Using the Web Interface

Tip: To force all HTTP accesses to the PDU to be redirected to HTTPS, see

(on page 90).

IP access control rules (firewall rules) determine whether to accept or discard traffic to/from the PDU, based on the IP address of the host sending or receiving the traffic. When creating rules, keep these principles in mind:

• Rule order is important.

When traffic reaches or is sent from the PDU, the rules are executed in numerical order. Only the first rule that matches the IP address determines whether the traffic is accepted or discarded. Any subsequent rules matching the IP address are ignored.

• Subnet mask is required.

When typing the IP address, you must specify BOTH the address and a subnet mask. For example, to specify a single address in a Class C network, use this format:

x.x.x.x/24

where

/24

= a subnet mask of 255.255.255.0.

To specify an entire subnet or range of addresses, change the subnet mask accordingly.

Note: Valid IPv4 addresses range from 0.0.0.0 through 255.255.255.255.

1. Choose Device Settings > Security > IP Access Control.

2. Select the Enable IPv4 Access Control checkbox to enable IPv4 access control rules.

3. Go to the Inbound Rules section or the Outbound Rules section according to your needs.

• Accept: Accepts traffic from all IPv4 addresses.

• Drop: Discards traffic from all IPv4 addresses, without sending any failure notification to the source host.

• Reject: Discards traffic from all IPv4 addresses, and an ICMP message is sent to the source host for failure

notification.

5. Create rules. See the tables for different operations.

• Click Append.

• Type an IP address and subnet mask in the IP/Mask field.

• Select an option in the Policy field.

 Accept: Accepts traffic from/to the specified IP address(es).  Drop: Discards traffic from/to the specified IP address(es), without sending any failure notification to the source or

destination host.

 Reject: Discards traffic from/to the specified IP address(es), and an ICMP message is sent to the source or

destination host for failure notification.

Role-based access control rules are similar to IP access control rules, except they are applied to members of a specific role. This enables you to grant system permissions to a specific role, based on their IP addresses.

Same as IP access control rules, the order of role-based access control rules is important, since the rules are executed in numerical order.

• Deny: Drops traffic from all IPv4 addresses regardless of the user's role.

4. Create rules. See the tables for different operations.

• Click Append.

• Type a starting IP address in the Start IP field.

• Type an ending IP address in the End IP field.

• Select a role in the Role field. This rule applies to members of this role only.

• Select an option in the Policy field.

 Accept: Accepts traffic from the specified IP address range when the user is a member of the specified role  Deny: Drops traffic from the specified IP address range when the user is a member of the specified role

• Select the rule above where you want to insert a new rule. For example, to insert a rule between rules #3 and #4, select

#4.

Setting Up an SSL/TLS Certificate

Important: The PDU uses TLS instead of SSL 3.0 due to published security vulnerabilities in SSL 3.0. Make sure your network infrastructure, such as mail services, uses TLS rather than SSL 3.0.

7. The rules are applied.

1. On the same page, select the "Enable Role Based Access Control for IPv6" checkbox to enable IPv6 access control

rules.

2. Follow the same procedure as the above IPv4 rule setup to create IPv6 rules.

3. Make sure you click the Save button in the IPv6 section, or the changes made to IPv6 rules are not saved.

You can modify existing rules to update their roles/IP addresses, or or delete them when they are no longer needed.

1. Choose Device Settings > Security > Role Based Access Control.

2. Go to the IPv4 or IPv6 section.

3. Select the desired rule in the list.

• Ensure the IPv4 or IPv6 checkbox has been selected, or you cannot select any rule.

4. Perform the desired action.

• Make changes to the selected rule, and then click Save. For information on each field, see

Rules (on page 98).

• Use the and buttons to arrange the order of the rules.

• Click to delete a created rule.

5. Click Save.

• IPv4 rules: Make sure you click the Save button in the IPv4 section, or the changes made to IPv4 rules are not

saved.

• IPv6 rules: Make sure you click the Save button in the IPv6 section, or the changes made to IPv6 rules are not

saved.

Having an X.509 digital certificate ensures that both parties in an SSL/TLS connection are who they say they are.
