C9400-SUP-1XL-Y Description
C9400-SUP-1XL-Y elevates the Catalyst 9400 platform with up to 240 Gbps per slot in a 4-slot chassis, plus on-board 8×10 G SFP+ or 2×40 G QSFP+ uplinks—software-selectable. The “-Y” variant enables up to 90 W per port when paired with Cisco UPOE+ line-cards. Built on Cisco’s programmable UADP 2.0 ASIC, it delivers wire-rate MACsec-256 on every access port, flexible SDM templates, and supports on-box analytics with optional NVMe SSD. Ideal for high-power PoE deployments in smart buildings and secure campus aggregation. Keywords: C9400 SUP 1XL-Y, Catalyst 9400 90W supervisor, C9400-SUP-1XL-Y.

Key Features
High-power PoE supervisor
Supports up to 90 W per port with Cisco UPOE+ line-cards, consolidating power and data in one module for IP cameras, Wi-Fi 6 APs, and LED lighting.
Up to 240 Gbps per slot
True line-rate for all 1 / 2.5 / 5 / 10 Gbps access cards in a 4-slot chassis, eliminating hidden bottlenecks under bursty IoT or video traffic.
Flexible uplink modes
Software-selectable mix of 8×10 G SFP+ or 2×40 G QSFP+ uplinks future-proofs aggregation without extra modules.
Wire-rate MACsec-256
Encrypts sensitive east-west and access-edge traffic in hardware, ensuring PCI-DSS, HIPAA and GDPR compliance with zero packet-loss.
Programmable UADP 2.0 ASIC
Enables model-driven telemetry, on-box Python, NETCONF/RESTCONF, and customizable SDM templates for agile network operations.
Carrier-grade resiliency
Stateful SSO/NSF (< 200 ms) and ISSU keep critical services online during upgrades, ideal for 24×7 environments.
Applications Scenarios
Smart-building PoE aggregation
90 W per port powers high-end cameras, digital signage and APs over single cable.
Secure campus distribution
240 Gbps fabric eliminates congestion for multigig uplinks; MACsec secures data.
IoT and sensor networks
Combines high PoE budget with on-box analytics for real-time health and usage monitoring.

Feature |
Description |
|---|---|---|
|
1 |
USB Type A Host Port |
This USB port is a host port for an external USB disk drive. It supports USB versions 3.0, 2.0, 1.1, and 1.0.See USB Type A Host Port |
|
2 |
USB mini Type B Console Port |
This USB port can be used as a console port, allowing attachment to PCs that are not equipped with an RS-232 interface.See Console Ports |
|
3 |
10/100/1000 Ethernet Management Port (RJ-45 connector) |
The Ethernet management port is a Layer 3 host port to which you can connect a PC. By default, the Ethernet management port is enabled. You can use the Ethernet management port instead of the switch console port for network management. This port is not active while the switch is operating normally.Note When connecting a PC to the Ethernet management port, you must assign an IP address.See Ethernet Management Port |
|
4 |
Console port (RJ-45 connector) |
This is an RS-232 serial or console port for system management.See Console Ports |
|
5 |
RESET switch (recessed) |
The RESET switch is used to reset and restart the switch.Note The reset switch is recessed into the front panel. Use a paper clip or a small, pointed object to press the RESET switch. |
|
6 |
1-GigabitEthernet (GE) or 10-GE, or 25-GE uplink ports |
The supervisor module has eight small form-factor pluggable (SFP) or SFP+ transceivers which support 1-GE or 10-GE modules. These ports are numbered 1 to 8.Ports 1 and 5 use SFP28 transceivers in 25G mode.Note In the accompanying figure, the ejector lever is not displayed in the redundant supervisor module only for the purpose of displaying the LEDs behind it.See Uplink Ports |
|
7 |
RFID |
Supervisor module Radio Frequency Identifier (RFID).Has a built-in, front-facing, non-removable, passive RFID tag that uses Ultra High Frequency (UHF) RFID technology and requires an RFID reader with compatible software. For more information, see Radio Frequency Identification (RFID) on Cisco Catalyst 9000 Family Switches. |
|
8 |
40-GE uplink ports |
The supervisor module has two 40-GE ports. These ports use QSFP transceivers. Ports are numbered 9 and 10.Note In the accompanying figure, the ejector lever is not displayed in the redundant supervisor module only for the purpose of displaying the LEDs behind it.See Uplink Ports |

What is “Line-rate” and 1 : 1?
|
Term |
Definition |
Design Impact |
|---|---|---|
|
Line-rate |
Fabric bandwidth equals the sum of all port speeds. |
Zero internal bottlenecks – every port can run at full speed. |
|
Oversubscription |
Fabric bandwidth less than total port speed. Expressed as 2 : 1, 4 : 1… |
Occasional congestion if many ports burst at once. |
|
1 : 1 |
No oversubscription (pure line-rate). |
Ideal for high-density Wi-Fi 6/6E, 100 G aggregation, low-latency apps. |
