Card provisioning and chassis modes

Overview

The behavior of the installed card depends on the chassis mode that has been configured on the device. The following table describes the behavior of the provisioned (configured) card types and installed cards in each chassis mode.

Table 15-1: Behavior of installed IOM cards

Provisioned card type	Installed card type	Behavior
2 x 10-Gig MDA IOM	2 x 10-Gig MDA IOM	The IOM card appears and behaves at the scaling limits of the 2 x 10-Gig MDA IOM.
	2 x 10-Gig MDA IOM Card, B	The IOM card appears and behaves as a 2 x 10-Gig MDA IOM. The 2 x 10-Gig MDA IOM Card, B is fully backward-compatible with the 10-Gig MDA IOM.
	2 x 10-Gig MDA IOM 2	The IOM card appears and behaves as a 2 x 10-Gig MDA IOM. The 2 x 10-Gig MDA IOM 2 is fully backward-compatible with the 10-Gig MDA IOM.
	2 × XP MDA IOM 3 ¹	The IOM card appears and behaves as a 2 x 10-Gig MDA IOM. The 2 x XP MDA IOM is fully backward-compatible with the 10-Gig MDA IOM.
2 x 10-Gig MDA IOM Card, B	2 x 10-Gig MDA IOM	The IOM card fails because the minimum card requirements are not met.
	2 x 10-Gig MDA IOM Card, B	The IOM card appears and behaves at the scaling limits of the 2 x 10-Gig MDA IOM Card, B.
	2 x 10-Gig MDA IOM 2	The IOM card appears and behaves as a 2 x 10-Gig MDA IOM Card, B. The 2 x 10-Gig MDA IOM 2 is fully backward-compatible with the 10-Gig MDA IOM Card, B.
	2 × XP MDA IOM 3 ¹	The IOM card appears and behaves as a 2 x 10-Gig MDA IOM Card, B. The 2 x XP MDA IOM 3 is fully backward-compatible with the 10-Gig MDA IOM Card, B.
2 x 10-Gig MDA IOM 2	2 x 10-Gig MDA IOM	The IOM card fails because the minimum card requirements are not met.
	2 x 10-Gig MDA IOM Card, B	The IOM card fails because the minimum card requirements are not met.
	2 x 10-Gig MDA IOM 2	The behavior of the card depends on the operational chassis mode: 2 x 10-Gig MDA IOM in chassis mode A 2 x 10-Gig MDA IOM Card, B in chassis mode B 2 x 10-Gig MDA IOM 2 in chassis mode C and D
	2 × XP MDA IOM 3 ¹	The behavior of the card depends on the operational chassis mode: 2 x 10-Gig MDA IOM in chassis mode A 2 x 10-Gig MDA IOM Card, B in chassis mode B 2 x 10-Gig MDA IOM 2 in chassis mode C and D
2 × XP MDA IOM 3 card ¹	2 x 10-Gig MDA IOM	The IOM card fails because the minimum card requirements are not met.
	2 x 10-Gig MDA IOM Card, B	The IOM card fails because the minimum card requirements are not met.
	2 x 10-Gig MDA IOM 2	The IOM card fails because the minimum card requirements are not met.
	2 × XP MDA IOM 3 ¹	The behavior of the card depends on the operational chassis mode: 2 x 10-Gig MDA IOM in chassis mode A 2 x 10-Gig MDA IOM Card, B in chassis mode B 2 x 10-Gig MDA IOM 2 in chassis mode C 2 x XP MDA IOM 3 in chassis mode D. With mixed mode enabled for 7750 SR, only the IPv6 features of the IOM3 card are enabled, but no other IOM3 features are available.
2 × XP MDA IOM 3, B card ¹	2 x 10-Gig MDA IOM	The IOM card fails because the minimum card requirements are not met.
	2 x 10-Gig MDA IOM Card, B	The IOM card fails because the minimum card requirements are not met.
	2 x 10-Gig MDA IOM 2	The IOM card fails because the minimum card requirements are not met.
	2 × XP MDA IOM 3 ¹	The behavior of the card depends on the operational chassis mode: 2 x 10-Gig MDA IOM in chassis mode A 2 x 10-Gig MDA IOM Card, B in chassis mode B 2 x 10-Gig MDA IOM 2 in chassis mode C 2 x XP MDA IOM 3 in chassis mode D. With mixed mode enabled for 7750 SR, only the IPv6 features of the IOM3 card are enabled, but no other IOM3 features are available.
