Monitoring

Monitoring and remote management

Every reporting line on an IDCPDU rack PDU carries a meter, 10/100M Ethernet and RS485. Readings leave over SNMP or Modbus, on an embedded web page, and on the OLED at the rack.

The monitoring parameter set

One row per parameter, so a monitoring scope can be written into a design file from top to bottom. Every value below is a published figure for the series, not an option list.

Interface

Ethernet and RS485 on one board

Both ports publish the same meter data, so a DCIM poll and a local tool can read the rack at the same time.

Which path fits the rack

Choosing the monitoring path

The paths answer different questions. A rack that is already polled by a platform, a rack nobody watches on a dashboard, and a rack that has to be reconstructed after a fault do not need the same depth.

SNMP and Modbus integration

For a rack that is already polled: the meter values leave as traps and registers and land in the platform in use.

Ethernet × 1 · RS485 × 1
Traps · registers
Read-only on values

Open SNMP & Modbus

Embedded web server and OLED

For a technician standing at the rack: the address, current and switch state are on the display, and the page needs nothing installed on a host.

Threshold alerts and SMTP

For a hall with nobody on the dashboard: the line raises the message itself when a value crosses the set point.

Settable per line
Entry written at the crossing

Open threshold alerts

Event log and RTC

For a fault that has to be reconstructed: the entry carries a date from the RTC and survives the power cut that caused it.

Up to 20,000 entries
RTC held through power loss
Read over Ethernet or RS485

Open event log

Every path reads the same meter board on the same unit. Selection follows what the site already runs, not the depth of the meter behind it.

Metering depth

A feed total and the outlet totals, from one board

A feed total and the outlet totals are written by the same board, so a rack can be billed per feed and audited per outlet without a second device. Both read at ±1% plus one digit, and the energy total is kept at 1 grade.

Feed total: ±1% + 1 digit
Outlet total: per outlet, on switched builds
Energy total: 1 grade · 0.1 kWh
Voltage reading: 90V ~ 350V · 1V
Current reading: 0.1A scale

The same five figures reach the OLED, the web page, an SNMP trap and a Modbus register.

What the readout reports

Each cell is a reading on the reporting line: the item, the value it is published at, and where it can be read from.

Current0.1A Total per feed, ±1% plus one digit

Power±1% Active power per feed, at the same accuracy as current

Temperature1°C Optional sensor over -30°C to 100°C, at the inlet or the rack front

Humidity1% Optional sensor covering 1% to 99%, reported beside temperature

Main switchOn/off Shown on the local display, so a technician reads it without a browser

AddressIPv4 Current address on the display, which shortens a service visit

One reading, several surfaces

The display, the page, the trap and the register

A sample is written once and read in several places, so a screen standing at the rack, a dashboard on the network and a billing export carry the same number. Only the reading path changes.

Local displayOLED Address, current, voltage, power, energy and main switch state

Web pageNo agent Served from the monitoring board to a browser on the same network

SNMPTrap Sent when a value crosses the threshold set for that line

ModbusRegisters Read over RS485, or over TCP on the Ethernet port

One meter board, one set of values. The path a site selects changes where the number is read, not what is measured.
