1 Gbps 1000Base-SX SFP transceiver

This HP 453151-B21 transceiver provides a single 1000Base-SX port operating at 1 Gbps. It is built for HP BladeSystem c-Class Virtual Connect environments. The module uses a small form-factor pluggable design for hot-swap installation.

Virtual Connect environments

The part suits administrators expanding or repairing HP BladeSystem c-Class Virtual Connect modules that require 1 Gbps multimode fibre connectivity. It is not for networks needing 10 Gbps speeds, single-mode fibre reach, copper RJ-45 interfaces, or compatibility with non-HP switching platforms.

1000Base-SX multimode fibre interface

The decisive specification is the 1000Base-SX interface, which limits the link to multimode fibre at 1 Gbps. Verify that the target Virtual Connect module accepts this SFP type before purchase.

Questions about this item

What slot type does the 453151-B21 SFP transceiver require?

The module uses the standard Small Form Factor Pluggable interface and fits any SFP-compatible port on HP BladeSystem c-Class Virtual Connect modules or switches.

How is the transceiver installed and what step is often missed?

Insert the transceiver into the SFP cage until it clicks, then connect the LC duplex fibre cable; the common mistake is leaving the dust caps on the optical ports.

When should the 453151-B21 module be replaced?

Replace the transceiver if link errors increase, the 1 Gbps 1000Base-SX connection drops intermittently, or the unit fails after a firmware update on the Virtual Connect enclosure.
