210-AFRR - Dell EMC S6100-ON Modular Switch, Reverse Airflow

Dell EMC Networking S6100-ON 2RU modular ToR switch, reverse-airflow AC base unit, 4 I/O slots, 2 SFP+ ports, supports 10/25/40/50/100GbE.

The Dell 210-AFRR is the manufacturer part number for the reverse-airflow AC base configuration of the Dell EMC (PowerSwitch) Networking S6100-ON, a high-performance 10/25/40/50/100GbE top-of-rack modular switch built for data center and high-performance computing environments. The chassis provides four empty I/O module bays that accept 16x40GbE QSFP+, 8x100GbE QSFP28, or mixed 100GbE CXP/QSFP28 modules, plus two fixed 1/10GbE SFP+ ports for uplinks or management traffic. It ships with two redundant, hot-swappable 1100W AC power supplies and fan modules configured for PSU-to-I/O (reverse) airflow, delivering a non-blocking 6.4Tbps switching fabric with up to 4400 Mpps forwarding and ultra-low L2/L3 latency, making it suitable for scalable, flexible network aggregation.

Per available Dell documentation, the 210-AFRR (S6100-ON) chassis is validated for use with the following components:

• 16x40GbE QSFP+ I/O module
• 8x100GbE QSFP28 I/O module
• 4x100GbE CXP + 4x100GbE QSFP28 combination I/O module
• 100GbE SR4 QSFP28 optical transceivers
• 100GbE LR4 QSFP28 optical transceivers
• 100GbE LR4Lite QSFP28 optical transceivers
• Dell 2RU Standard ReadyRails rack mounting kit (compatible with S6100-ON, Z9264F-ON, S5296-ON)
• MTP-to-LC breakout cable kits (1RU 64-port and 48-port variants)
• Matching reverse-airflow AC power supply and fan modules (must match chassis airflow direction)

Note: Airflow-direction components (fans and PSUs) must match the chassis build; the 210-AFRR is the reverse-airflow (PSU-to-I/O) variant and cannot be mixed with normal-airflow (210-AFRS) parts without a full, powered-down component swap.

• Dell EMC PowerSwitch S6100-ON chassis (empty I/O module slots)
• 2 x hot-swappable 1100W AC power supplies (reverse airflow)
• Fan modules (reverse airflow, matching PSU direction)
• Grounding accessory kit with UL-certified GND lug and mounting nuts
• Basic documentation/quick start reference (I/O modules, rail kits, and transceivers sold separately)

Q: What is the Dell 210-AFRR part number?

A: 210-AFRR is Dell's manufacturer part number for the reverse-airflow AC base configuration of the Dell EMC PowerSwitch S6100-ON modular switch, as confirmed by Dell's official spec sheet.

Q: Does the 210-AFRR include I/O modules or transceivers?

A: No. The 210-AFRR ships as an empty-slot base chassis with power supplies and fans installed; I/O modules (e.g., 40GbE QSFP+ or 100GbE QSFP28) and optical transceivers must be purchased separately.

Q: What is the difference between 210-AFRR and 210-AFRS?

A: Both are AC base units of the S6100-ON chassis; the difference is airflow direction — 210-AFRR is the reverse-airflow build (PSU to I/O panel), while 210-AFRS is the normal-airflow build (I/O to PSU panel).

Q: What is the switching capacity of the S6100-ON?

A: According to Dell and third-party specification sources, the S6100-ON delivers a non-blocking switching capacity of 6.4Tbps with a forwarding rate of up to 4400 Mpps in full duplex mode.

Q: Does the Dell 210-AFRR support Power over Ethernet (PoE)?

A: No. Multiple distributor listings confirm that PoE is not applicable to this switch model, as it is designed for high-speed data center aggregation rather than device power delivery.

Q: What operating systems does the S6100-ON support?

A: As an Open Networking (ON) platform, the S6100-ON supports Dell Networking OS9, with the option to run alternative networking operating systems available on Dell's ON hardware.

Q: What are the physical dimensions and weight of this switch?

A: Per third-party technical documentation, the chassis measures 2RU (17.08" W x 18" D x 3.5" H) and weighs approximately 34 lbs (15.42kg) with base PSUs and fans, or about 44 lbs (20kg) when fully populated with four I/O modules.

Q: Can the airflow direction of the 210-AFRR be changed later?

A: Yes, but only while the unit is powered down and all fan and power supply modules are replaced with parts matching the new uniform airflow direction, per Dell's official installation documentation.
