NOTE: This upgrade only applies to Lab kits with 1921/1941 Routers & HWIC-1DSU-T1 Cards
Lab kits with 1921/1941 Routers include 2 Serial Ports that are normally implemented with HWIC-1DSU-T1 Cards (with RJ-48 Sockets)
And these Cards require the use of T1 Serial Cables with RJ-48 Connectors.
Therefore, our Premium Lab kits also include 3 x T1 Serial Cables
But when adding this upgrade, the Serial Cards and the Serial Cables will be replaced with:
- 3 x HWIC-2A/S Serial Cards (replace all HWIC-1DSU-T1 cards in the Routers)
- 3 x Smart-Serial Cables (replace all T1 Serial Cables with RJ-48 connectors)
Please notice that ISR G2 Routers like the 1921 & 1941 don't support older WIC Serial Cards
like WIC-1DSU-T1, WIC-2A/S, WIC-1T or WIC-2T.
They only support the newer Cards, known as High-Speed WAN Interface Cards or HWIC.
Therefore, HWIC-1DSU-T1's can only be upgraded to another HWIC card like the HWIC-2A/S
