WS-C4006-S2

Identify the S2 order before comparing replacement hardware

WS-C4006-S2 belongs to the modular Catalyst 4000 family. Cisco’s December 2002 product guide distinguishes this six-slot Supervisor II order from the bare WS-C4006 spare chassis and the WS-C4006-S3 Supervisor III order. Its historical order description lists two AC power supplies, a fan tray and rack-mount kit. Those catalog contents identify the order code; they are not a current packing list or stock photograph. Ask for the actual chassis and supervisor labels plus an itemized quotation. A similar chassis name does not establish the installed control engine or included accessories.

Separate Supervisor II from II-Plus and inventory the line cards

The same official guide associates WS-X4013 with Catalyst 4006 Supervisor II. It is a different identifier from WS-X4013+; an II-Plus module must not be assumed from the S2 suffix. The chassis has six module positions, one reserved for the supervisor, leaving five for other modules. The populated line cards determine the access-port count and media. Obtain the module part numbers and installed software output before choosing replacement cards or optics. The family catalog lists multiple card types, so a six-slot chassis alone does not establish a fixed Ethernet port count, PoE budget or a ready-to-use Layer 3 configuration.

Match two-supply operation to the configured power budget

Cisco’s Catalyst 4006 administration guide describes three power-supply bays. A fully loaded chassis needs two primary supplies. Under the default 2+1 mode, two fitted supplies provide no spare-supply redundancy; a third supplies the redundant role. The alternative 1+1 mode can use two supplies for redundancy only when the complete module load fits within one supply’s capacity. It does not support every populated configuration. Review the actual supply labels, module load and configured budget together. Do not infer redundancy, a 1000 W replacement rating or current-unit power consumption from the historical S2 order description.

Use the historical software table as a compatibility starting point

Cisco’s Release 5.x hardware table explicitly lists WS-C4006-S2 as a six-slot modular chassis and gives 5.4(2) as its minimum supported supervisor software in that historical table. This is a legacy compatibility reference, not a recommendation to run that image today, proof of the installed version or a current maintenance commitment. Cisco’s Supervisor I/II troubleshooting guide uses show version, show module and show system to establish the actual software, module state and power information. Request these readouts and a successful diagnostic record before accepting an installed-base replacement.

Define the offered condition and scope in the quotation

Confirm that the seller’s condition description matches the actual unit, seals, serial labels and test evidence. Record the supervisor, line cards, power supplies, fan tray, rack hardware and any optics separately; include software rights and current support eligibility in the quotation review. The official series photograph shows Catalyst 4003 on the left and Catalyst 4006 on the right. It illustrates the historical family only, not this offer’s equipment or configuration. No exact lifecycle date, available quantity, delivery date or manufacturer warranty is inferred from the catalog. Compare the final inventory with the existing installation before authorizing a replacement.
