XIOM modules are modules that are used in 7750 SR-1s/2s/7s/14s platforms. These can be installed into an XCM instead of installing an XMA module. The XIOMs have two slots that support MDA-s modules (see MDA-a, MDA-aXP, MDA, MDA-XP, MDA-e, and MDA-s modules).
The use of an XIOM introduces an additional index into the reference hierarchy. For example, a 7750 SR-14s with an XCM in card slot 1 can have an XMA in the first slot and an XIOM in the second slot. A possible configuration is shown in the following example:
#--------------------------------------------------
echo "Card Configuration"
#--------------------------------------------------
card 1
card-type xcm-14s
mda 1
mda-type s36-100gb-qsfp28 level cr1600g
no shutdown
exit
xiom x2
xiom-type iom-s-3.0t level cr1600g+
mda 1
mda-type ms2-400g-qsfpdd+2-100g-qsfp28
no shutdown
exit
mda 2
mda-type ms16-100g-sfpdd+4-100g-qsfp28
no shutdown
exit
no shutdown

no shutdown

On the 7750 SR-1s/2s/7s/14s, the MDA-s modules are supported when an XIOM is installed into a slot within an XCM. Up to two MDA-s can be installed in an XIOM. MDA-s names in CLI start with the letters "ms" (for example, ms16-100g-sfpdd+4-100g-qsfp28).
