Which supervisor engines does C9404R support, and does it support two?

C9404R supports C9400-SUP-1, C9400-SUP-1XL, C9400-SUP-1XL-Y, C9400X-SUP-2 and C9400X-SUP-2XL, and it supports a redundant pair. The two dedicated supervisor slots are 2 and 3, and dual supervisors run 1+1 with NSF/SSO and ISSU under 200 msec. Line cards are not supported in those slots.

Which power supply redundancy modes does C9404R support?

C9404R supports redundant N+N, redundant N+1 and combined mode, with AC or DC supplies in every mode. Its 4 bays take C9400-PWR-3200ACT, C9400-PWR-3200AC, C9400-PWR-2100AC or C9400-PWR-3200DC, ordered as separate line items. N+N halves usable output and N+1 reserves one supply.

How many fans are in the C9404-FAN tray of C9404R and what happens if two fail?

The C9404-FAN tray holds 8 fans. If one fan fails, the other fans in the same row speed up. If two or more fail, the whole tray runs at full speed after one minute and must be replaced. The tray is nonredundant as a unit and can be serviced from the front or the rear, per the Catalyst 9400 hardware installation guide.

How many 90W UPOE+ ports can C9404R supply with C9400-LC-48HX or C9400-LC-48HN cards?

C9404R can supply 90W on 96 ports when both line-card slots hold these cards. The C9400-LC-48HX count assumes C9400X-SUP-2 or C9400X-SUP-2XL and fully loaded 3200W supplies in combined mode. The C9400-LC-48HN count is quoted at maximum power. Size the power supplies for fully loaded cards before ordering.

Does C9400-LC-48P run at full line rate in C9404R with C9400-SUP-1?

Yes. The 48-port 1G cards such as C9400-LC-48P need only 48G per slot, and C9400-SUP-1 gives 80 Gbps per line-card slot in C9404R. These cards run at line rate on every supervisor, so a newer engine does not raise their speed.

Which supervisor does the C9404R configurator select by default?

The configurator makes the supervisor mandatory and defaults to C9400-SUP-1XL, which includes StackWise Virtual and a 240 GB SSD. A second supervisor is optional. The power supplies need a power cord selection or CAB-OPTOUT, and C9404R takes at most 2 line cards, per the Catalyst 9400 ordering guide.

Which line card types can be ordered for C9404R?

C9404R takes up to 2 line cards. Copper cards come as multigigabit or 1G with UPOE+, UPOE, PoE+ or data-only power. 1G fiber and 10G fiber cards are also available. Add C9400-S-BLANK= for each slot left empty, per the Catalyst 9400 ordering guide.

Maximum Access Ports

Key Features

Two Line-Card Slots, 96 Access Ports

Slots 1 and 4 take line cards, so the chassis tops out at 96 access ports with any supervisor. Port counts above that need a larger chassis, not a newer supervisor.

240 Gbps Per Slot On Supervisor 1XL

C9400-SUP-1XL and C9400-SUP-1XL-Y give each line-card slot 240 Gbps here, the same rate as C9400X-SUP-2. In the 7-slot and 10-slot chassis the same supervisors fall to 120 and 80 Gbps.

Four Power Supply Bays For Two Slots

Four bays serve only two line cards. N+N redundancy can run on two supplies with two bays left free, or combined mode can add headroom for fully loaded UPOE+ cards.

Dedicated Supervisor Slots

Slots 2 and 3 accept supervisors only, so a single-supervisor build leaves one slot empty. A second supervisor adds 1+1 redundancy with NSF/SSO and ISSU in under 200 msec.

6 RU Front-Mount Chassis

The chassis measures 10.47 x 17.30 x 16.30 in. and weighs 39.0 lb (17.2 kg) with its fan tray. It mounts in a 19-in rack from the front, and no shelf install kit is listed for it.

Software Baseline By Supervisor Generation

Cisco IOS XE 16.9.1 runs the chassis with the C9400-SUP-1 class. Installing C9400X-SUP-2 or C9400X-SUP-2XL raises the minimum to Cisco IOS XE 17.7.1, which also unlocks 25G, 40G and 100G ports.

Application Scenarios

Small Campus Collapsed Core

In a single-building or small multi-tenant campus, the chassis acts as a collapsed core, terminating up to 96 fiber or copper links on two line cards while a redundant supervisor pair carries the routing.

Shared Communications Rooms

Wiring cabinets with limited height can take the 6 RU chassis, including sites where network gear shares an enclosure with other equipment.

Redundant Branch Aggregation

A large branch or remote site that needs dual supervisors and multiple power feeds can aggregate its access layer on the chassis, which operates from -5 to +45 degrees C up to 6,000 feet.

Product Comparison

Parameter	C9404R	C9407R	C9410R
Line-card slots	2	5	8
10/100/1000BASE-T (RJ-45) ports	96	240	384
100 Gigabit Ethernet ports (QSFP28)	8	20	32
PoE power budget per line-card slot	4320W	4320W	4320W
Per-slot bandwidth with C9400-SUP-1XL	240 Gbps	120 Gbps	80 Gbps
Number of power supply bays	4	8	8
Rack units	6 RU	10 RU	13 RU
Shelf install kit	None listed	C9407-SHELF-KIT=	C9410-SHELF-KIT=

C9404R is the smallest chassis in this group, with 2 line-card slots, up to 96 access ports and 8 100G QSFP28 ports in 6 RU, against 5 slots and 240 ports in C9407R and 8 slots and 384 ports in C9410R. A site that expects more than 96 access ports or more than two line cards moves to C9407R at 10 RU, or to C9410R at 13 RU when it needs up to 32 100G QSFP28 ports. Sites reusing C9400-SUP-1XL get 240 Gbps per line-card slot only in C9404R, because the same supervisor delivers 120 Gbps in C9407R and 80 Gbps in C9410R. Cisco lists a shelf install kit only for C9407R and C9410R.

PoE Power Planning

Planning Item	Value or Check
PoE standards	IEEE 802.3af and IEEE 802.3at plus the Cisco pre-standard power implementation on every Catalyst 9400 chassis and PoE power supply
PoE budget per line-card slot	4320W with current shipping line cards; the chassis is capable of approximately 4800W per slot
Power supply bays	4 bays, populated with C9400-PWR-3200ACT, C9400-PWR-3200AC, C9400-PWR-2100AC or C9400-PWR-3200DC
Redundancy mode	Redundant N+N halves usable output, redundant N+1 reserves one supply, combined mode sums all supplies against the share ratio
3200W AC supply output	55V at 58.0A on the 230VAC range and 28.36A on the 115VAC range, 20 ms holdup, 950 BTU/hr heat dissipation per unit
2100W AC supply output	55V at 38.21A on the 230VAC range and 17.09A on the 115VAC range, 20 ms holdup, 460 BTU/hr heat dissipation per unit
3200W DC supply output	55V at 58.0A from a -48 to -60 VDC input drawing 36A per input, 8 ms holdup
Input line voltage effect	The 115VAC range caps the 3200W AC supply at 1560W and the 2100W AC supply at 940W per unit against 3190W and 2102W on the 230VAC range, which changes how many supplies a given PoE load needs
Powered-device count	Sum the per-port class draw of the installed PoE line cards against the active budget rather than the per-slot maximum

Ordering Checklist

Supervisor engines: Slots 2 and 3 take the supervisor: one of C9400-SUP-1, C9400-SUP-1XL, C9400-SUP-1XL-Y, C9400X-SUP-2 or C9400X-SUP-2XL, with a redundant /2 PID such as C9400-SUP-1XL/2 for the second. Line cards are not supported in these slots, and the chassis order does not choose the supervisor.
Line card and supervisor pairing: Pair C9400-LC-24XY, C9400-LC-12QC, C9400-LC-48HX, C9400-LC-48TX and C9400-LC-48XS with C9400X-SUP-2 or C9400X-SUP-2XL, because the C9400-SUP-1 supervisor class does not support them.
Power supplies: Fill the 4 bays with C9400-PWR-3200ACT, C9400-PWR-3200AC, C9400-PWR-2100AC or C9400-PWR-3200DC, with quantity set by the redundancy mode. The 115VAC range derates the 3200W AC supply to 1560W and the 2100W AC supply to 940W, so a PoE load can need more units.
Blank covers: Add C9400-S-BLANK= for each empty line-card slot and C9400-PWR-BLANK= for each empty power supply bay. Covers are separate order lines, not part of the chassis PID.
Chassis-specific kits: Add C9404-FAN=, C9404-ACC-KIT= and C9404-RACK-19-KIT=; no shelf install kit is listed for this chassis. The C9407 and C9410 kits are built for taller chassis, and the 4 slot chassis has no shelf kit to fall back on.

C9404R supports C9400-SUP-1, C9400-SUP-1XL, C9400-SUP-1XL-Y, C9400X-SUP-2 and C9400X-SUP-2XL, and it supports a redundant pair. The two dedicated supervisor slots are 2 and 3, and dual supervisors run 1+1 with NSF/SSO and ISSU under 200 msec. Line cards are not supported in those slots.
Which power supply redundancy modes does C9404R support?
C9404R supports redundant N+N, redundant N+1 and combined mode, with AC or DC supplies in every mode. Its 4 bays take C9400-PWR-3200ACT, C9400-PWR-3200AC, C9400-PWR-2100AC or C9400-PWR-3200DC, ordered as separate line items. N+N halves usable output and N+1 reserves one supply.
How many fans are in the C9404-FAN tray of C9404R and what happens if two fail?
The C9404-FAN tray holds 8 fans. If one fan fails, the other fans in the same row speed up. If two or more fail, the whole tray runs at full speed after one minute and must be replaced. The tray is nonredundant as a unit and can be serviced from the front or the rear, per the Catalyst 9400 hardware installation guide.
How many 90W UPOE+ ports can C9404R supply with C9400-LC-48HX or C9400-LC-48HN cards?
C9404R can supply 90W on 96 ports when both line-card slots hold these cards. The C9400-LC-48HX count assumes C9400X-SUP-2 or C9400X-SUP-2XL and fully loaded 3200W supplies in combined mode. The C9400-LC-48HN count is quoted at maximum power. Size the power supplies for fully loaded cards before ordering.
Does C9400-LC-48P run at full line rate in C9404R with C9400-SUP-1?
Yes. The 48-port 1G cards such as C9400-LC-48P need only 48G per slot, and C9400-SUP-1 gives 80 Gbps per line-card slot in C9404R. These cards run at line rate on every supervisor, so a newer engine does not raise their speed.
Which supervisor does the C9404R configurator select by default?
The configurator makes the supervisor mandatory and defaults to C9400-SUP-1XL, which includes StackWise Virtual and a 240 GB SSD. A second supervisor is optional. The power supplies need a power cord selection or CAB-OPTOUT, and C9404R takes at most 2 line cards, per the Catalyst 9400 ordering guide.
Which line card types can be ordered for C9404R?
C9404R takes up to 2 line cards. Copper cards come as multigigabit or 1G with UPOE+, UPOE, PoE+ or data-only power. 1G fiber and 10G fiber cards are also available. Add C9400-S-BLANK= for each slot left empty, per the Catalyst 9400 ordering guide.
