Honeywell 900ES1-0100 Ethernet Switch Module 8-Port

Description

Key Technical Specifications

Product Introduction & Supply Chain Strategy

The Honeywell 900ES1-0100 is an 8-port unmanaged industrial Ethernet switch module engineered specifically for integration within the HC900 ControlEdge process controller chassis. It routes high-speed data communications between local controller processors, expansion I/O racks, and plant SCADA or HMI networks.

Securing this module as New Surplus provides significant Total Cost of Ownership (TCO) benefits over third-party hardware or used components. Unplanned network downtime on an HC900 rack halts critical loops in water treatment, chemical batch processing, or boiler controls. Buying verified New Surplus avoids the high failure rates of aged electrolytic capacitors found in refurbished modules while eliminating OEM lead times.

Installation & Configuration Guide

Stage 1: Pre-Installation (Prep & Safety)

1. Perform Lock-Out/Tag-Out (LOTO) procedures on the target HC900 rack power supply.
2. Put on a grounded ESD wrist strap connected to the chassis frame ground terminal.
3. Inspect the replacement 900ES1-0100 backplane connector pins for transport damage or debris.
4. Label all incoming Ethernet cables matching their assigned port numbers (Ports 1–8).

Stage 2: Removal

1. Disconnect all RJ45 network cables from the front of the active 900ES1-0100 module.
2. Unfasten the top and bottom retaining screws securing the module to the rack frame.
3. Pull the module retention levers outward simultaneously to disengage the backplane connection.
4. Slide the module straight out along the chassis guide rails.

Stage 3: Installation (Clone & Seat)

1. Verify that no mechanical obstruction exists within the empty rack slot.
2. Align the new 900ES1-0100 module top and bottom printed circuit board edges with the chassis guide rails.
3. Slide the module firmly into the rack until the backplane connectors seat completely.
4. Tighten the top and bottom retaining screws to 0.4 Nm (3.5 in-lbs) to ensure proper ground continuity.

Stage 4: Power-On & Testing

1. Reattach all labeled RJ45 Ethernet cables into their corresponding ports.
2. Restore 24 V DC power to the HC900 rack chassis.
3. Observe the module Power LED to verify solid green status upon initialization.
4. Confirm that the Link/Activity LEDs for all connected ports flash green to indicate active network handshake and data traffic.

Firmware/Software Versions & Upgrade Notes

The 900ES1-0100 functions as a layer-2 unmanaged switch module. It operates independent of specific CPU firmware versions and does not require IP address allocation or software configuration files.

• Firmware Dependencies: None. Operating system software (HC Designer or Process Control Designer) routes traffic transparently through the 900ES1-0100 hardware layer.
• Compatibility Notes: Drop-in compatible across all CPU controllers (including C30, C50, C70, and C75 redundant models) and expansion chassis.
• Hardware Revision Advisory: When replacing legacy hardware revisions, ensure that physical cable strain reliefs are re-installed. The module requires no DIP switch settings or memory chip transfers.

Frequently Asked Questions (FAQ)

Q: Is this 900ES1-0100 module brand new or has it been pulled from a working panel?

A: This product is a Brand New Surplus unit. It is not used, not pulled from a decommissioned plant, and not refurbished. All modules undergo rigorous quality verification to ensure OEM-level reliability.

Q: Why is your price lower than Honeywell list price, but higher than pulled or used units?

A: Our pricing reflects the cost of securing genuine New Surplus inventory globally. It may be 20–30% higher than a refurbished gamble, but it is substantially less than OEM list prices, and it buys you 100% peace of mind. Refurbished network cards often carry hidden silicon degradation that leads to random dropouts under heavy network load.

Q: Can I hot-swap the 900ES1-0100 module while the controller is running?

A: While the system supports module replacement under specific conditions, powering down the local rack slot during physical insertion prevents transient voltage spikes on the backplane power rail. If operating a non-redundant system, pulling the switch breaks communication to connected expansion racks, causing a controller fault.

Q: Does this switch require an IP address setup via HC Designer software?

A: No. The 900ES1-0100 is an unmanaged layer-2 switch. It handles MAC address learning automatically at the hardware level. No network configuration, bootp setup, or software parameter assignment is required.

Q: What warranty coverage applies to this New Surplus module?

A: We provide a full 1-year functional warranty from the date of delivery. If the module fails operational parameters during normal plant use within this window, we provide an immediate advance replacement from stock.
