WS-CBS3110G-S-I is an IBM BladeCenter switch module with 14 internal Gigabit server downlinks and four fixed Gigabit copper uplinks, combining chassis-integrated connectivity with IP Base software. The managed Layer 2+ module belongs to the Catalyst Switch Module 3110 family and is not a standalone desktop or rack-mount switch. Cisco Catalyst Switch Module 3110 for IBM BladeCenter uses Virtual Blade Switch technology to present interconnected modules as one logical switch. Its fixed uplink design requires no removable uplink card, and the external connections use copper rather than SFP cages. WS-CBS3110X-S-I differs by providing a 10 Gigabit Ethernet X2 uplink slot. The Gigabit configuration connects blade servers inside the enclosure to external network equipment through its front-panel Ethernet interfaces.

128 Gbps maximum switching fabric capacity serves the module's internal and external Ethernet interfaces without changing individual port speeds. 35.5 Mpps maximum forwarding applies to 64-byte packets, so retain that frame-size condition when comparing performance figures. Static routing and RIPv1/v2 handle basic IPv4 forwarding under IP Base; full OSPF, EIGRP, and BGPv4 routing is not included in that image. STP, RSTP, and MSTP provide spanning-tree options, while LACP supports EtherChannel connections. WS-CBS3110G-S-I includes 256 MB DRAM and 64 MB flash for running Cisco IOS and storing software and configuration. SDM templates allocate hardware resources differently between MAC learning and unicast routing, so the largest scale figures belong to different profiles. The module uses BladeCenter power and cooling rather than a separate switch power supply. 45W maximum consumption establishes the module's contribution to enclosure power sizing; account separately for the remaining installed chassis components.
WS-CBS3110G-S-I is available new sealed or certified refurbished from ORM Systems, with up to 3-year extended warranty for new units and up to 1 year for certified refurbished units; returns are available for 30 days on every condition, terms apply. Certified refurbished modules are inspected and bench-tested for power-on and POST, every port linking at rated speed, clean boot, and stack adapter negotiation, with firmware verified and configuration wiped to factory default. Specify condition, quantity, and the required licensed configuration when ordering this switch. Purchase orders are accepted, government buyers can use Net-30, and enterprise or volume orders can include RMA with advance replacement across the UK, EU, US, and MEA.

A replacement module for an existing IBM BladeCenter estate must match the enclosure, not just the Cisco family name. The 3110G supports BladeCenter E, T, H, and HT; MSIM installations require Advanced Management Module firmware 1.42i or later. Record each enclosure type and management firmware revision before ordering a common spare pool.
Adding WS-CBS3110G-S-I to an established stack requires a membership-change plan. Merging powered-on stacks triggers a master election, and switches outside the elected master's existing group reload and adopt that master's configuration. Identify the configuration that must remain authoritative, then specify the addition procedure and maintenance window before placing the PO.
An IBM BladeCenter staging program needs management access before production uplinks are enabled. The module includes one internal 100BASE-T management interface, separate from its server downlinks. Establish enclosure management connectivity, credentials, and the intended software feature set before acceptance testing, then specify the accepted configuration on the purchase order.
Native 10G external uplinks
WS-CBS3110G-S-I has fixed 1G copper uplinks and no 10G uplink slot. Its external interfaces cannot become 10G connections by fitting an optical transceiver.
Installation in BladeCenter S
WS-CBS3110G-S-I is not supported in the IBM BladeCenter S enclosure. Compatibility with BladeCenter E, T, H, and HT does not extend to BladeCenter S.
OSPF without a license upgrade
WS-CBS3110G-S-I includes IP Base rather than IP Services. OSPF requires the 3110-IPS-LIC-I upgrade; specify that license when OSPF must be enabled at delivery.

WS-CBS3110G-S-I identifies the Cisco Catalyst Switch Module 3110G for IBM BladeCenter with IP Base software. The 3110G hardware name identifies the Gigabit-uplink configuration; the complete ordering identity ties that module to IBM BladeCenter and IP Base. Specify the full part number rather than a shortened family name when matching an existing module.
WS-CBS3110G-S-I supports the browser-based device manager, Cisco IOS CLI through console, SSH or Telnet, Cisco Network Assistant, CiscoWorks LMS, and SNMP management. SSH requires the cryptographic software image. VBS members are managed as one logical switch with a single management IP address rather than separate management identities for each member.
Cisco has not announced an end-of-sale date for Catalyst Switch Module 3110 for IBM BladeCenter. WS-CBS3110G-S-I is the IP Base Gigabit variant for that enclosure family. For procurement, specify hardware condition separately from any requested Cisco support coverage; the part number alone does not establish an active service contract.
ORM Systems offers WS-CBS3110G-S-I new sealed or certified refurbished, with up to 3-year extended warranty for new units and up to 1 year for certified refurbished units. Cisco's platform hardware warranty is 90 days, separate from ORM coverage. Returns are available for 30 days in every condition; terms apply.
WS-CBS3110G-S-I includes IP Base, with 3110-IPS-LIC-I for IP Services or 3110-AISK9-LIC-I for Advanced IP Services. IP Services adds advanced IPv4 routing; Advanced IP Services adds IPv6 routing. Cisco IOS software activation enables the feature set matching the module's license file. Specify the upgrade PID and required feature set separately on the purchase order.
WS-CBS3110G-S-I has four fixed external 10/100/1000BASE-T uplinks and does not provide a 10G uplink slot or SFP cages. These are copper connections, separate from the internal server downlinks. Specify external copper cabling and upstream port settings before ordering; an optical transceiver cannot convert this fixed-uplink model into a 10G module.
WS-CBS3110G-S-I supports a nine-member Catalyst Switch Module 3110 stack through its two StackWise Plus ports. VBS presents the stack as one logical switch. Other blade-switch types cannot join this stack. Confirm member compatibility before ordering an expansion module, and plan membership changes around the existing master configuration and the intended maintenance procedure.
No, WS-CBS3110G-S-I does not include OSPF in its supplied IP Base feature set; OSPF requires IP Services. Static routing and RIPv1/v2 are included in the base configuration. Request 3110-IPS-LIC-I when advanced IPv4 routing is required, and distinguish the installed software license from the hardware part number during acceptance testing.
WS-CBS3110G-S-I supports IBM BladeCenter E, T, H, and HT, but not BladeCenter S. Installation through the BladeCenter Multi-switch Interconnect Module requires Advanced Management Module firmware 1.42i or later. Match the enclosure and management firmware before ordering; a module fitting another BladeCenter configuration is not sufficient evidence of compatibility.
Catalyst Switch Module 3110 for IBM BladeCenter provides 128 Gbps maximum switching fabric capacity and 35.5 Mpps maximum forwarding for 64-byte packets. These are hardware performance figures rather than external uplink speeds. Keep the packet-size condition beside the forwarding rate when comparing quotations, and distinguish module capacity from the speed of individual connections.
WS-CBS3110G-S-I has four 1G copper external uplinks, whereas WS-CBS3110X-S-I has a 10 Gigabit Ethernet X2 slot. Both are IBM BladeCenter modules in the 3110 family, but their external connection types differ. The G model suits an existing copper Gigabit uplink requirement; the X model addresses a BladeCenter installation requiring a 10G connection.
Catalyst Switch Module 3110 for IBM BladeCenter supports 12000 MAC entries with the VLAN template or 11000 IPv4 unicast routes with the routing template. These are different resource allocations, not simultaneous maxima. Specify the intended SDM template before acceptance testing so MAC learning and routing requirements are assessed against the same configuration.
WS-CBS3110G-S-I uses 12V chassis power, consumes a maximum of 45W, and relies on BladeCenter cooling rather than a separate switch power supply. Include that module consumption when sizing the enclosure power allocation. The module is not a standalone AC switch, so the supporting enclosure must be available for installation and bench testing.
