VIM-2x Ethernet Module Port Option Card
The VIM-2x Ethernet Module option card, shown in Figure 144, allows you to add up to two 10-gigabit
SFP+ optical ports to the VIM slot on the rear panel of the X460-G2 series switch. These ports support 1
GbE and 10 GbE SFP and SFP+ transceivers.
Caution
VIM modules are not hot swappable. You must power down the switch before installing any
VIM modules.

TM-CLK Clock Module
The TM-CLK Clock Module provides an Oven-controlled Crystal Oscillator (OCXO) for use as a reference
frequency for SyncE and 1588v2 precision time features. The OCXO is precise to +-2 nanoseconds (ns)
with time accuracy +50 to -65 ns. The ExtremeXOS configuration selects the input to the clock module
from a SyncE master port or a 1588v2 grandmaster clock. The TM-CLK module is required for SyncE on
the X460-G2. The 1588v2 Precision Time feature on the X460-G2 requires the TM-CLK module and the
Network Timing Feature Pack, and does not support stacking.
Two mini-BNC outputs deliver the following signals:
• 10MHz frequency reference
