WS-C4503-E-S2+48 is the Cisco Catalyst 4503-E data bundle with one 1000AC supply, one Supervisor II-Plus and one WS-X4148-RJ module. The E chassis suffix distinguishes it from WS-C4503-S2+48.

WS-C4503-E-S2+48V is the Cisco Catalyst 4503-E PoE bundle recorded with one 1300AC supply, one Supervisor II-Plus and one WS-X4248-RJ45V module. It is not the S2+48 data bundle.

WS-C4503E-S6L-1300 is a Cisco Catalyst 4503-E bundle with a Supervisor 6L-E, one WS-X4648-RJ45V+E line card and a 1300W power supply. Confirm the fitted parts against the quotation.

WS-C4507R-E is a seven-slot Cisco Catalyst E-Series chassis with supervisor positions 3 and 4 and five switching-module positions. Supervisor 8-E/8L-E requires chassis hardware revision 2.0 or higher.

WS-C4503-E is a Cisco Catalyst 4500 E-Series three-slot chassis. Slot 1 is for one supervisor; slots 2 and 3 accept switching modules. It does not support a redundant supervisor pair.

WS-C4503-S2+48 is a legacy Cisco Catalyst 4503 bundle: one 1000AC supply, one Supervisor II-Plus and one WS-X4148-RJ 48-port 10/100 module. The access module is not a 48-port Gigabit card.

C9400-S-BLANK= is Cisco’s slot blank cover for the Catalyst 9400 Series. Cisco lists C9400-PWR-BLANK= separately as the power-supply blank cover, so the two blanking components are not interchangeable order identities.

Cisco IE-4000-8T4G-E is an industrial Ethernet switch with eight Fast Ethernet copper downlinks and four Gigabit combo uplinks. It is not the 8GT Gigabit-downlink variant.
CISCO buyers should validate software and license tier, PoE budget and uplink module, airflow, power supply and stacking compatibility. Use the active catalog below to compare exact part numbers and open each product page for specification, condition, price and official-source details.
Start with the exact manufacturer part number rather than the marketing family name. Then compare the technical configuration, included licenses and accessories, product condition, warranty responsibility, lead time and destination-specific requirements. For replacements, validate interoperability with the installed software, optics, power and management platform.
YYST Global product pages provide model-level specifications and official manufacturer references where available. Procurement teams can use these pages to prepare a bill of materials and then request confirmation of quantity, serial-number availability, shipping and acceptance terms.
